Insomnia – I am making some progress on it, but not much, but when I woke up at 1:30 am this morning I at least could see stars. We have had a pretty steady dose of mostly cloudy, hazy, foggy, partly cloud and heavy rains lately – 7 inches one day, five inches more a few days later and about an  inch yesterday  – so clear skies have been unusual and don’t last long.

These clear skies lasted long enough for me to get the 66mm  WO scope out and after a false start – batteries are weak on the Celestron mount I suspect – I got it on the Desert Sky dual mount/Bogen tripod and had a good time with some old friends.

I actually have a little plan in mind – to establish a list of best objects for popular consumption on any given night – or more accurately, any given sidereal/star time – of the year.  My goal would be for these objects to be nice in any scope, so if they’re nice in the 66mm you can be pretty sure they’ll be nice in anything larger.  The 66mm thus establishes a base line. So my observations were made with this in mind.

Yes, I’m pretty sure I could make such a list from memory – but I would trust it more if I check each object with this in mind.

So – up for starters was, of course, Albireo. It did fine at 16X – was really pristine – but I think the newcomer would appreciate it more at 30X. Once they were certain what they were seeing, they could try backing off some.

I have a soft spot for Albireo, but I closed this session wilth Almach and I have to say that although it was pretty low in the east at this time, I still find its colors richer than Albireo. It does take significantly more power. I found it best at 78x, though it could certainly be split with less.

There’s no contest with the Dragon’s Eyes – they are a perfectly matched pair that’s pretty easy to split in binoculars and certainly split easily at 16X, but seem better framed at 30X.

Meanwhile the Dolphin presents more of a challenge. Gamma Delphini is a sort of pale version of Albireo – in fact I would have a sliding scale of intensity for blue and gold stars where I would rank Almach the most intense, then Albireo, and then Gamma Delphini. Needed about 50X to get a decent split and it was better at 79X.

I liked M13 at all powers from 16X to 79X – but it was best at 79X because at that point I could really see individual stars flashing across the main body of this star ball.

M31 was another object that did fine at all powers, though it was easier to pick out M32 at 79X.

As I think – and write – about this experience I basic process for visitors pops into my mind. I want to start them witht he naked eye view. From there, I’ll move them to low power binoculars on amount – just to let them know what they can expect to see with their own binoculars.  Next up would be the 66mm at 16X and on a tracking mount, tobe followed by the 5-inch SCT on tracking mount a with a 24-8 zoom. Finally they could go in the observatory and use the 8-inch SCT,

Last step? Show them a good image  – probably in the observatory and under red light –  of what they’ve been looking at and encourage them to go back and look again.

And in this process define a “glance” as one minute at the scope – a “look” as three minutes or more.

My last post here was almost a year ago – what the heck have I been doing?

Well, not much of what I would really call observing, though I had an hour and half this morning that felt right. For one thing for reasons I can’t explain I have been ignoring my best and easiest observing venue – the Observatory. So in thepast week I’ve made up my mind to get back to it.

Hey, the LX-200R is in “park” so all I have to do is open the shutter and turn on the scope. And I did about 2:20 am today and swung it to M11, the Wild Ducks – and found them hiding behind a tree! No problem – I swung over to M27 which I had taken a long look at a couple mornings ago. It was well placed and while the transparency was below par – I coud see a faint Milky Way, but nothing like I would like to – I did get a chance to really use the new (used) set of Meade Ultra-wide eyepieces I have acquired.

First, however, I looked with my inexpensive 30mmOwl “finder” eyepiece. This is an 82 degree AFOV and really quite good – especially considering it costs me $40 on the used market and that included a lens I can screw into it to bring it to 20X. Haven’t tried that yet, but I like it as a constant “finder” eyepiece for this scope and honestly, I don’t see much difference between it and the Meade UW 30mm except that the adjustable eye shield ont he Meade makes it easier for me to use.

I made a sketch – very rough – and a few notes of M27 and M57 observation, plus some notes on the Double Double. I closed up shop at 4 am as it was getting quite light.

Couple things I need to do –

Get oriented. I need to make it second nature what the directions and PA are when using this scope.

Get a better chair – my current stool doesn’t go low enough and it is difficult to observe object as high as M57 was when I was looking at it – 74 degrees – not all that high!

On M27 I noted some key field stars, so I should be able to figure the orientation from that.  I could see one star on the edge of – or just in the Nebulae and I believe from my reading this is a star to the southwest.

Best framing for this object came with the 18mm UWA. In fact, that also provided th ebest framing for M57.

I could just dig out the nearby 12th or 13th mag star on the edge of M57 that I have seen many times. That had to be an indicator of the poor transparency.

With the Double-Double I could split it starting with the 18mm and the 14mm probably gave th ebest split, though it was  hard to choose between that and the view in the 8.8mm.   However, I couldn’t get any of the views to reallys ettle downa nd give me the pristine, round stars I like with the  refractor. Masking the scope – bringing it down to 60mm – did give me nice round stars and again the best split came with the 14mm.  (The mask turns this into an F33 scope! The 14mm means I’m using 143X with a 60mm scope. Fifty times aperture should be the maximum power – about 112X – so I was luck to be getting a decent image with that 14mm.

Well, I really thought we were doomed to watching the historic transit of Venus – last one for 105 years – on the web.

I had been ready to drive any where in the Northeast to see it, but the whole Northeast was socked in tight. I saw some hope in the few hours before it when this cloud pattern appeared.

This was the local cloud pattern about an hour before the transit was slated to start.

That gave me a slight ray of hope, but half an hour before it was to start I went outside and we were 100% overcast, so I settled down to watching the web cast from NASA, though the car was loaded with scopes for a quick trip to Gooseberry should things improve. The web cast  was slated to start at 5:45pm EDT.  I picked it up and we slowly moved towards the start of the transit a few minutes after 6. Right about  6 I decided to check on the weather satellite once more and darned if it didn’t show a hole over us – something I would have seen if I had looked out! Bren and I rushed out and I set up the TV85 and little Ha solar scope on a dual mount at the end of the driveway, unpacking it from the car. ( I had been planning to go to Gooseberry.) I hastily sent out an email telling folks I would be observing here.

And we did! Bren and I got a wonderful view right at the start of the transit and off and on for the next 45 minutes. I also had put one of the cheap solar filters I had bought for binoculars over the Rebel’s 300mm lens and I took several shots with it. What I got wasn’t anything to write home about, but hell, it was a picture and pretty much captured what we had seen. What struck us both was the size of Venus – larger than expected – the crispness of the little dot, and the blackness of it – much blacker than the array of sunspots easily visible below it.

This one was taken at 6:22:38 pm EDT using the 300mm – ISO 200, shutter speed 100 F5.6.

This second shot was taken at 6:27:13 pm EDT at ISO 200, 1/300th second and F5.6. I took many shots between these two trying different shutter speed and tweeking the focus because I could not be sure when I had a sharp image.

Karen Davis came over with Mason from next door and they both got a good look at the event.  Then some guy came by in a car, saw us, and stopped. He was using apiece of smoked glass that he seemed to have confidence in and said he could see it with the naked eye. Judy Beavan showed up as well, the only one on my email list besides Karen. And a little later another newcomer – Susan Czernicka. Susan wrote me immediately upon getting home:

I’m your excited neighbor from 1414 down the road who is feeling fortunate beyond words to have happened upon you out on the road.  I can’t thank you enough for enabling me to see the the transit.  Please add me to your email list.

So all in all, it was a nice event.  John Nanson saw it through breaks in the clouds from Oregon, and Dom and Daphne got great views – again through holes – with telescopes at the Sydney Observatory. Checked in on some of the Web coverage from time to time as well. Here’s a typical screen shot.

Meanwhile, real science was done during this transit by observing light reflected from the Moon and getting a reading on that which will help with studying extra-solar planets. Plans are being made for similar observations of the transit as seen from Jupiter and from Saturn later this year when the alignment for those planets is correct.  For details, see this article.

Binoculars set up in Observing Shelter awaiting darkness for testing with doubles - and really testing me more than the binoculars. Unitron is there to check seeing conditions and acts as control of sorts - so to the Sparrow Hawk. (Click image for larger view.)

Until the past week I have never seen really sharp stars in binoculars – and what’s more, I assumed that was normal – that what I wasn’t seeing, others were not seeing.

Wrong!

Maybe decades worth of wrong. How many decades?  I’m not sure simply because it’s been relatively recently that I made a serious attempt to see double stars with binoculars and splitting close doubles is the most demanding resolution task of both the instrument and the observer.

From my experience I’ve developed some basic guidelines for splitting doubles with binoculars.  They are:

1. Wear your glasses if you have astigmatism – otherwise do without

2. Sit down – or better, lie back in a lawn chair – you must be comfortable

3. Hold the binoculars steady – even 7X50s will benefit from being on a tripod, or parallelogram mount unless, of course, they are image stabilized types

4. Focus carefully – very carefully –  first the left eye with center focus, then do the diopter adjustment for the right eye while keeping the left eye closed

5. Spend time on target – Look for at least one solid minute – don’t expect instant success.

6. Relax your eyes – let them focus at a distance and get used to it

7. And if all else fails, maybe you have a problem similar to mine – back off from the eyepieces an inch or two, move your head about some – find the correct head position – the one that works and yields sharp stars.

What follows is all about my own special case of “if all else fails” – because believe me, points one through six didn’t make a difference for me until I could settle the issue of point 7 and right now I’m not sure how many others have a similar problem, but I think it’s relatively few.

OK – the point is, I have been happily using binoculars for years without realizing I wasn’t getting the most out of these instruments – not even close to the most. Oh, I’ve seen galaxies out to  50 million light years or more – and I’ve gotten all sorts of expansive views of star clusters and nebulae. But I suspect what I discovered a few days ago may actually enhance  viewing of those objects as well.  What did I discover? That binoculars can, indeed, deliver “refractor-like” images of double stars. Let me be as clear as I can about this.

Double stars should look like the stars in the images to the right. That is, they should look like nice round discs with clean edges. Now any star that is low in the sky is  likely to throw out spikes of light, change colors, and dance about in any instrument just because in that instance you are looking through an awful lot of moving air.

But, if they are overhead or roughy 45 degrees or higher – and the air is average steady, then you should see nice sharp images when your instrument – binocular or telescope – is properly focused.

I do with telescopes – I don’t with binoculars – or didn’t up until recently and still don’t unless I am especially careful.  Is this my special problem? It may be. I have evidence there are some others who share it, but I suspect most people see the sharp stars they should, assuming their binoculars are held very steady – or are of the image stabilized variety – and they have been focused well.

Now let me emphasize that telescopes give me no problem – I can always see sharp, clean images with telescopes when seeing conditions are good. And while I am most likely to see the best images of doubles with either a long focal length refractor, or an apocromatic refractor, I get good, clean star images with any well-adjusted telescope of any design. Not so with binoculars. There the images have been consistently poor for me and I’m still not sure why. but lately I’ve come to suspect that my head simply isn’t screwed on straight – something critics have been telling me for years 😉

Determining what to expect with binoculars – that is, which doubles will split with binoculars  –  is much different than with telescopes. Double star fans know that all doubles aren’t created equal – and that the main problem is how far apart they are in angular measure – usually stated in seconds of arc.  A typical binocular has a field of view of between 2 and 8 degrees depending on how powerful it is. A typical binocular double is separated by less than one minute of arc. So when we are talking about stars separated by, say 30 seconds of arc, we’re talking about a distance that is just 1/120th of a degree. If your binoculars show a six degree field, then this pair of stars is taking up  about 1/700th of that field of view. Darned little.

So you also typically put the pair of stars in the middle of your field of view and the middle of the field of view is where even poor quality binoculars tend to perform quite well. Stars half way out to the edges may start to deform and stretch, but in the center they are sharp.  That’s why I say – and my experience confirms – that quite inexpensive binoculars can perform reasonably well when splitting doubles.

That is the first piece of big news I pulled out of my recent Eureka Moment.

The second was a handy rule of thumb I stumbled across when researching this subject trying to figure out what the heck was wrong with me. Telescope resolution – or expectations of resolution – are typically guided by something called the Dawes Limit which is entirely dependent upon the size of the objective  – a bigger objective creates smaller star images (in terms of angular size)  and will thus split stars that are closer together – it’s as simple as that. Now double star observers no it’s not really that simple – that frequently when the pair of stars have one that is much dimmer than the other, this rule crumbles because the dimmer star gets lost in the glare of the brighter one.

But if we are talking about stars that are within a couple of magnitudes of one another in brightness, the Dawes limit is a good starting point for determining how close stars can be and still be split.  The problem is, this rule assumes you are using fairly high magnification – say 30 times your objective diameter in inches. With binoculars you are almost always using much lower magnification. For example, my 10X30 image stabilized binoculars deliver only about eight times the objective diameter in inches. And my 25X100 binoculars have a power just four times the objective diameter in inches.

But Gary Seronik, in his small book “Binocular Highlights” suggests another rule of thumb that applies to binoculars – simply divide the power of your binoculars into 300. The answer is the separation, in seconds of arc, that those binoculars should be able to split. Thus my 10X30 binoculars – or 10X50 – should be able to split two stars that are separated by 30 seconds of arc. Albireo, a very popular double, is separated by 34 seconds of arc, so the 10X glasses should split it. My 25X100 should be able to split  stars that are 12 seconds of arc apart – that means the very popular double Mizar – which is separated by about 14 seconds – should split in the 25X binocular – and, indeed, it does. However, my 20X glasses will probably have problems with it  – 300/20=15 – and they do, though I have been able to split Mizar with those glasses, it’s difficult. So I think this is an excellent – though rough – guide. (The Dawes limit on those 25X100 binoculars, btw, is  barely a second  of arc – but that is a totally unrealistic expectation for binocular performance. Dawes limit = 4.56 Arc Seconds / Objective Diameter (inches) so 4.56/4 = 1.14. In fact, it is rare for a telescope to achieve this resolution on a double, but something like 1.8″ of arc is a reasonable expectation for a 4-inch t eleescope.)

But these numbers have not mattered much to me when using binoculars. I have only split the widest doubles. So, for example, over the years I really needed 15X binoculars to get a good, obvious split of the Dragon’s Eyes – Nu Draconis – a charming pair of 5th magnitude stars a wide 60 seconds of arc apart. Now, the new me finds them simple with just 10X30 binoculars.  Fifteen power glasses should, by this rule, be able to split stars just 20 seconds apart. The Dragon’s eyes should fall to binoculars as low as five power!  What’s more, in the past when I split this pair I didn’t get the kind of clean, “bullet hole”, stars shown in the image – I got dancing stars – bloated, jiggly stars throwing out spokes of light. It’s just that the 15 power binoculars – and the wide split – made it possible for me to see this pair as  two stars – and I assumed everyone was seeing the same thing.

But I was puzzled how observers I respect and admire like Seronik and Ed Zarenski, to mention just two, routinely split stars that were far, far closer together and instead of bragging about their amazing eyes and observing skills, seemed to think that others could routinely do the same. I know I couldn’t.

It must be my eyes. They must have problems I’m not aware of. That was my first train of thought and I’ve been pursuing that one for the better part of a year – without staisfaction. And a recent trip to the eye doctor confirms my practical experience – there’s nothing seriously wrong with my eyes. In fact, I have what the doctor describes as a “slight astigmatism” – so slight that they say that if I get corrective glasses I will barely notice the difference – and though this doctor worked with folks who sold glasses, she didn’t recommend them for me. (I ordered them anyway – there was  a special on where they’ll cost just $50 and this is something i have to see for myself because this whole business is driving me more than a little crazy.)

The Breakthrough

My breakthough came on a morning when I had decided to test five different binoculars –  10X30IS Canons, 15X70 Celestron Skymasters, 20X60 Pentax, 20X80 Celestrons,  and 25X100 Zhummels.  With the exception of the image stabilized Canons, all would be tested mounted on one of two parallogram mounts. The largest of these mounts was on a pier and really too tall for me to use sitting down, so I was using that one standing.  As a way to check the seeing and to make sure I could actually split these particular stars at low power, I had two small refractors set up as well – a 60mm Unitron using a 40mm Kellner eyepiece for roughly 24X and a 50mm Stellarvue Sparrow Hawk that was a lot like a single binocular in that it used a prism diagonal and was of very short focal ratio – F4.1. I used a 20mm eyepiece in this to get 10X, so it was, in many ways, a good match for the Canon 10X30IS.

My targets were the doubles Albireo (34.4″), Zeta  Lyra (44″), Nu Draconis -Dragon’s Eyes–  (62″), and Mizar (14.3″) – all were at a good altitude on this spring morning.

Initial tests

And the notes from my initial test showed nothing went particularly well at first.  This was the old me.

Actually, I started in the early evening with Mintaka – a wide  split at 52.8″ of arc that should be easy with all the binoculars I was testing, except there also is quite a difference in magnitude –  2.4, 6.8. That 4.5 magnitude difference makes Mintaka a bit of a challenge.  But the 25X100s showed it well. The 20X80s gave me a good look, though not quite as good as the larger binoculars. Actually, the best view came with the 20X60s – not sure why, but this is the old me talking.  I’m seeing a split, but the primary is shooting fire. The 10X30IS gave me an occasional glimpse.  The best view came with the Unitron with the 40mm Kellner, so this was roughly comparable to the 20X60 binoculars, but the star images were much better. I assumed that was because it was a long focal length refractor – and that probably was part of the reason, but as I later learned, didn’t account for all the difference.

The point here is that even the old me could split some doubles – just not nearly as well as I later learned was possible.

I moved on to the much more challenging Mizar. The 10X30IS couldn’t split it – no surprise. The separation is too little for those binoculars. Here I drew a quick sketch of what I saw with the 20X60s because the stars were so bloated and dancing so much I couldn’t be sure I was seeing a split, but I thought I was.  When I checked with the 60mmUnitron I was sure – the binocular view was correct – but, there was absolutely no comparing the two views. The Unitron – at roughly the same power- was far, far cleaner than the binoculars. (Remember, at 20X you should barely be able to split  Mizar – the formula says 15″ is  the minimum separation. Mizar is 14.3″ – though the stars are fairly close in magnitude –  2.2    and  3.9.) The 25X100 gave me a certain split, but certainly NOT “refractor-like” stars.

But something strange was starting to happen. As I maneuverd the binoculars on the parallelogram mounts they were sometimes a few inches from my eyes and once in a while I got a glimpse of sharp stars such as I saw in the Unitron. This first happened with the 20X80 Celestrons and it came when I seemed to bend my head back and literally look down my nose from an inch or two behind the eyepieces. I was tired. I was getting cold. And I really didn’t know what was going on, so I went in with the intention of getting four hours sleep and trying again when I was refreshed.

Morning session

Field notes on Albireo - at last, a clear view.

Nothing comes easily to me – especially in terms of binoculars. I wrestle with mounts, I fiddle endlessly with focus, and mostly I have ended end up seeing something like this:

I have a sense of two stars here, of course, but theimages are dancing, the colors swapping sides, and sometimes I think I see the secondary in one place, sometimes in another.

When I should see – and now do see –  this:

What a delight! This is what I'm used to seeing with a telescope and now - with more and more consistency and less and less hassle, can see with binoculars.

In one sense the change was nearly instantaneous – that is, I would go from a terrible image to a perfect one – no inbetween.  But it only happened after a lot of work and a lot of false steps.

What made me put in the extra effort was I justc ouldn’t reconcile the diffferent experience of using two very nice instruments on Albireo. The first was the Stellarvue Sparrow Hawk aka Little Rascal. This is a 50mm finder, essentially, but  it takes standard eyepieces and is easy to focus. But like a binocular it has a very short focal ratio – F4.1 – and it uses a prism to deliver an erect image. And as my notes show, when I pointed it at Albireo on this particular morning with a 20mm eyepiece (10X) I got a “clean and delicate” split just as I would expect with any telescope – though this wasn’t any telescope. this was essentially half a binocular.

Then when I switched to the 10X30IS Canon’s I was back in Blursville with dancing stars.  And then I started to notice something. I noticed it with the large, mounted binos – the 25X100 Zhummel and the 20X60 Pentax, and 20X80 Celestrons. If I backed my eye way off – I’m talking two or three inches from the eyepieces – and tilted my head so I was in effect looking down my nose  there were long moments when the two stars snapped into sharp focus. Crazy? I’m not sure. When Ibrought this up in a Cloudy Nights discussion forum a few people came forward to talk of similar experiences – but on a few.

Believe me , my heart was racing. I have looked at countless double with binoculars and I had never seen them like this.  This was a real breakthrough and I quickly skipped about from Albireo to Zeta Lyre, to the Dragon’s Eyes and then to Mizar. With these kargerf binoculars everything was great – really great with the bright image sof the 25X100,

I couldn’t believe my luck. I hadn’t even brought out the 10X30IS for this session because I had about given up on them. Twilight was starting to grow brighter in the east. I quickly went back to the house, got the 10X30IS, and voila! There was a perfect Albireo – a yellow star with a scrumptious blue pinpoint right next to it.  I simply couldn’t believe it.  It was every bit as good as I had seen in the tiny Sparrow Hawk refractor.  The only question that remains is why the heck did it take me half a century of observing to discover this?

Well, not the only question. Since this breakthrough I have had three more sessions under the stars and I have expanded the variety of stars I’m looking at to include 16 & 17 Draocnis, Regulus, and Psi Draconis.  I have had my eyes examined by a professional and asked her for ane xplanation – why the heck do I have to look down my nose at doubles? And I have discussed it in online forums and with Larry Patriarcha, the guy who makes and sells the best parallelogram mounts  I know of.  Allt hese people had ideas, but no really firm answers.

But here’s the rub. This is getting easier and easier for me to do – that’s good news, but doesn’t solve the puzzle. I am finding with practice I now achieve this state of double star nirvana without half trying. But it still is easiest to reach if I back off form the eypieces, then, once i get it, approach them slowly being careful to maintain my head position.

So I think it does have something to do with head position – after all, with binoculars you look up – with many telescopes using diagonals you look down.  And it may have some tiny thing to do with astigmatism, and it may have to do with stressing my eye muscles by tiltilting my head back and looking down my nose. But two things are clear to me – first, most observers don’t seem to experience this problem. Second, I don’t understand fully why I do, nor do I understand fully the solution because the ground rules seem to be slipping out from under me. There definitely is a groove and I find it easier and easier to get in it. And believe me, I’m not complaining. This opens up a whole new area of especially enjoyable observing for me.

Doubles I love. I always have found a magic in seeing two perect little globes next to one another.  But now I can see them with both eyes open and while leaning back in a comfortable lawn chair and looking up at the sky – and that, for me, really is double star nirvana.

After a hiatus of about four years I am back into deep sky video astronomy with both feet. The object of this form of astronomy is to provide live video views at the telescope – under the stars – which show far more detail in faint, distant objects than can be seen visually with the eye at the telescope. The video camera, a special one made by hand in Canada by Rock Mallin, simply slides into the telescope where the eyepiece normally goes.

This is not rocket science, but there are a lot of options, a lot of wires, and some stuff to learn, so at this stage my efforts are crude, but I’m happy with the results. I don’t see this as competing with still imaging where much different cameras are used to take super pictures which are then enhanced the next day in the computer.  What you see here is raw video – what you would see if you stood by the telescope and looked at the video screen. I discussed the reasons for doing this  in detail in a post about six years ago when I first tried deep sky video.

Yeah, Driftway Way Observatory looks a bit techy these days with all the wires and things 😉 That little screen about the size of a deck of cards is the recording device from Orion. It includes a nice monitor which is shown here displaying a menu. The whole thing is small and light enough to ride ont he telescope. (Click image for a larger view.)

Last night I tried for the first time  an Orion StarShoot LCD-DVR recorder – this is a new item – so new the Orion sales and technical folks could not answer my questions a couple weeks ago because they hadn’t seen one yet. So I decided to buy one and give it a try, since Orion has a reasonable return policy. My assessment? Neat. I like it. But then. I’ve only spent an hour with it. However, let’s cut to the chase. Here are most of the recorded videos from last night.

My first stop was M3, a globular cluster , and the different versions of it you see on the followingvideo are due to my playing with the MallinCam controls -sometimes taking very short exposures, sometimes longer ones. Also, the  drives on the LX-200R hadn’t really settled down yet, so you don’t get a satisfying – to me – view until the end of this brief clip.

About viewing these clips –

1. Enlarge to full screen if possible by clicking box in lower left.

2. Don’t treat like a normal video – there is no relevant sound and there is virtually no action. When you see something you like, pause and view as a still image.

3. Make liberal use of the slider beneath the video to jump from one section of the video to another.

Colliding galaxies

This next one is of one of my favorite galaxies – or rather, colliding galaxies – M51. Though I have viewed this countless times over the past 40 years or more, this is the first time I was really aware that the core of the smaller galaxy is much brighter than the core of the larger one. (I explore just that idea in another video later.)

I jumped from M51 to a much different subject, the Owl Nebulae in Ursa Major – M97.  I have always found this planetary nebular difficult visually, but in the video it’s fairly easy to see how it got its nickname. This won’t be obvious until I increase the exposure in the second half of the video.

From the Owl I went to another difficult, but astounding subject, m101, the great Pinwheel Galaxy just off the Big Dipper’s handle. This is notoriously hard to see visually, but the spiral structure, while subtle is easily seen – especially in the longer exposures near the end of this video.

M81 is best known, perhaps,a s the companion of M82. The two galaxies are fairly near to one another – and to us (11 million light years) and both can be seen int he same binocular field of view. They are quite different. M81 is a bright spiral – however, the spiral structure takes alot of exposure to bring out and only becomes apparent inthe second half of this video.

OK, I wasn’t born yesterday, and the number of scopes I’ve owned and used extensively is well over 100, so why am I getting excited about  a cheapy version of a SCT “go to?”

SE6 after an enjoyable first hour of exploring the universe through the clouds and cold.

And I guess the answer is it just proved itself to be a very acceptable performer optically and electronically – and for my particular needs at this particular stage in my life, it’s a very good fit. Of course there are better optics available – and in a modern SCT.  But the combination of my old eyes, plus what I expect out of an astronomy experience, plus price, ease of use, and ease of transport and set up makes this little scope hard to beat. It is just what I was hoping it would be.

It arrived late yesterday afternoon from Amazon.com in one big box and was simple to unpack and set up – but it was raining of course – freezing rain. So I read the manual. Even though I was pretty familiar with the system from past experience,  I needed a refresher. I put some batteries in the scope and played a little to get the feel of it, pumping in my latitude and longitude, a one-time thing –  and I decided that the two-star alignment would work best for me because I know the stars – I don’t need the scope to pick them for me – and because I planned to use it on the deck where only about 40 percent of the sky is available to me, so stars the little sand brain choose would likely be behind a tree or house that it didn’t know was there. Then I went to bed with not much hope of using it in the morning.

But I was wrong. I awoke around 3:30 am and when I peeked out the bedroom window, there was Mars & Company screaming for me to come out. Without getting dressed I went down stairs and put the scope out the sliding glass doors onto the deck to cool down. Then I relaxed, put on some long underwear and made some tea. By 4 am I was entering the time and date and choosing Arcturus for my first alignment star. Of course I hadn’t had a chance to align the red dot finder, but it wasn’t that far off. A little scrolling brought the orange brilliance of Arcturus into a 32mm Plossl (46X and a tad over one degree FOV I suspect.) I then choose Vega and through  a hole in the clouds, found it, though by this time Arcturus had been smothered.

Did I mention the bright stars that beckoned me were  in a  sucker hole? If not, you now know the derivation of that term – they sucked me right out into the 30-degree night – had me walking gingerly, as flat-footed as possible, over a deck that had  a fresh dusting of snow on it. And yes, there were clouds moving fairly quickly across the stars, covering a significant percentage of the sky at any given moment. That’s why the first “go to” failed. I tried for M57 and immediately found it covered. It may have been barely visible, but I thought this is a silly choice for these conditions and 46X. So I went to M3 which was in the open at the moment – and darned if it didn’t put it pretty much in the center of that 32mm eyepieces – and I loved it! Well, loved it for the next 30 seconds before the clouds took over again.

But I pulled up my observing chair and started going through my small collection of cheap Plossls – nothing fancy here – that I had put in the eyepiece tray/spreader  – the 25mm Plossl that came with it, plus a 20, 15, and 10 of mixed heritage that came out of the box of long-ignored eyepieces. I never did try the 10 – nor the barlow. I just didn’t get the conditions and I was too enthralled with the view of M3 followed by M5 to want to fool around with changing eyepieces. I was comfortable sipping my tea and enjoying the sights both in the scope and with my naked eye. Passing clouds can be fun sometimes, first revealing, then hiding, then revealing again.

My last target was Mizar and while it didn’t place it dead center, it certainly worked – and the view was surprisingly sharp. I mean, classic, bullet-hole stars as long as I placed my head directly over the eyepiece. ( I don’t know if this is a symptom of old age, SCT optics, or the particular  Plossls I was using, but getting your head position just right sure does make the difference between flaring stars and good crisp ones. )  In any event, I used Mizar to do at least a rough alignment on the red dot finder.

Oh – and I wasn’t using the AA batteries I put in it – I was using a Power Tank I had handy and that’s obviously the way to go.  And with the Mizar sightings the clouds really got serious. But I had an hour of off-and-on viewing and  enough time to feel really impressed with the scope, though I never even checked collimation which, after its journey from wherever the heck these are made, is probably off, though the view of Mizar seemed to say it couldn’t be too far off.

Here’s what I liked:

1. Convenience. I can leave it set up next to the sliding glass door and at 21 pounds I can pick up the whole thing – including eyepieces – and have it outside in seconds. Another few seconds for grabbing the Power Tank, my observing chair, and tea and I’m home free. Putting it away is every bot  as easy.

2. The “go to” system. Until very recently I had sworn off these entirely.  Now I’m wondering why? What the hell am I trying to prove and to whom? That I know how to connect the star dots? That I don’t need a computer to find stuff for me in the universe?  Sure, that’s true – but with “go to” I can dispense with the connect-the-dots games. There’s a danger of losing a sense of context, but my continued binocular use gives me plenty of that.  And heck, I can add, subtract, multiply and divide in my head pretty well – but I would still rather use a calculator most of the time.

3. Tracking is right on and I love it. I went   and out several times when the clouds came over. I spent plenty of time in  a warm room with a red light on, giving my hands a chance to catch up with the rest of my body – they do get damned cold, damned fast. And when I came out the object I was viewing was right there int he center of the eyepiece waiting for me.

4. Optics. The sharp stars in the globulars and the bullet hole stars of Mizar were evidence enough for me that I was not making a huge sacrifice here. Yes, the contrast is down a little and yes, I wouldn’t mind having a little more light grasp. but six inches is enough to show me the kind of major deep sky objects I enjoy – the ones that have the power to develop that coveted sense of awe.

And that sense   awe has a better chance of finding me if I’m not all wrapped up in simply finding the next object, or  toying with complex eyepieces – or for that matter, binoviewers. Yeah, I’m cooling on them again.  We’ll see – but right now I’m thinking they add weight, instability, and complexity to the system and that all may be more than its worth to use two eyes at the scope. But we’ll save that for another day – or night, rather.

Meanwhile, I’m looking forward to trotting down to Gooseberry with this modest scope and taking on Mercury – hope it will be high enough and I can see it soon enough to get a clear picture of its phase.

Well, the Quadrantids were a drizzle at best for me – either this “shower” came early, or came late, or didn’t come at all. Haven’t seen other reports yet – but it wasn’t there for me. And now, too late, I discover there’s a new “app” designed by NASA to help you record what you see during a meteor shower and automatically send it to NASA to help their research!

Wow! Maybe that’s why it held off – I wasn’t properly prepared! 😉

Seriously folks, I saw one great Quadrantid meteor – it was fabulous – right up there with the best half dozen of meteors I’ve seen in  more than half a century of sky watching.  It came at 10:15 pm last night as I boldly stepped out onto the deck in the  18-degree cold – sub zero, really, with the strong wind we had – and bang, I was warmed up by a meteor  that took so long to go from the area of the Great Bear to  somewhere near Procyon that I could have called you and told you to look had I your number and my phone handy.

It was a fireball of at least magnitude -2 – the brightness of Jupiter. And sooo slow – well, I would estimate it took three seconds to cross the sky, but who’s counting/ –  and it looked, for all the world, like a plane going down in flames.  And no sound.  Just an eerie silence as it flared near the end. And I thought “what a great way to begin a night of meteor  observing – yes, and to end it. I should have quit when I was ahead.  I stayed out about 15 minutes and saw no more and rather than freeze I came in and settled down at the sliding glass door = room lights off of course –  where I could see a good segment of sky to the northeast and I watched and saw nothing. Now I won’t say I watched until midnight. I wrote the time downs and I took breaks – but I watched a lot and amidst the moonlight, saw nothing.

So some time after midnight I curled up on the couch and went to sleep and awoke about 2:30 am.  Ahhh – still clear, despite the forecast. OK – I got really warmly dressed ( it was now 15-degrees Fahrenheit) and went out again.  And to make a long story short in a solid half hour of being out and looking up  I saw three meteors – a short little dude near the Dipper again, now very high in the north, a really decent one in the northwest that zipped towards Capella, and another very nice one in the south heading down below  Leo.

All I observed were observed when outside – though I looked for much longer stretches from inside – always giving it at least 20 minute  watches. Now inside I maybe lost half a magnitude – but that still gave me magnitude 4.5 skies – very decent for meteor watching.

I  NEVER see anything like the advanced predictions for  various meteor showers. But I consider a good shower one where I can see about 20 an hour – and this could generously be put at 6 an hour for me.

Now about that APP – it looks intriguing. I learned about it on Spaceweather.com this morning. It’s put out by the NASA folks who keep track of meteors. Here’s part of the NASA pitch for the APP which you can download from the APP Store at Apple for free.

Surprising but true: Every day, on average, more than 40 tons of meteoroids strike our planet.  Most are tiny specks of comet dust that disintegrate harmlessly high up in Earth’s atmosphere, producing a slow drizzle of meteors in the night sky.  Bigger chunks of asteroid and comet debris yield dozens of nightly fireballs around the globe. Some are large enough to pepper the ground with actual meteorites.

With so much “stuff” zeroing in on our planet, NASA could use some help keeping track of it all.

Enter the Meteor Counter–a new iPhone app designed to harness the power of citizen scientists to keep track of meteoroids.

“Using our app, people from all walks of life can contribute to authentic NASA research,” says Bill Cooke of NASA’s Meteoroid Environment Office, which sponsored the project. “The data will help us discover new meteor showers, pinpoint comet debris streams, and map the distribution of meteoroids around Earth’s orbit.”

Whenever you go outside for a bit of stargazing, take your iPhone, iPad or iPod Touch with you, advises Cooke.  Start the Meteor Counter, lie down in a safe dark place, and be alert for shooting stars.

The Meteor Counter operates using an intuitive “piano key” interface. Every time you see a meteor, simply tap the key corresponding to its brightness.  Keys on the left correspond to dim meteors—barely visible to the naked eye; keys on the right denote jaw-dropping fireballs.

After the observing session, the app uploads your data for processing by NASA personnel. [video] [download]

With each keytap, the Meteor Counter records critical data such as the time you saw the meteor, the meteor’s magnitude, and your location.  You can even turn on an optional voice recorder to capture your own description of events.  Experts could comment on the trajectory and radiant of the meteor, while novices might prefer to simply shout out–“wow!”

Afterward, these data are automatically uploaded to NASA researchers for analysis.

Hey, is that cool – or what? Well, it would have been freezingly cool this morning. Too cool for me – and too cool for the Quadrantids, apparently.  Hope others had better luck. Me -I’m heading off to the APP store to get the Meteor APP and give it a try. As NASA urged:

Cooke encourages citizen scientists everywhere to try it out.

“The app is available free of charge in Apple’s app store,” he says.  “Just search for Meteor Counter, and let the observing begin.”
