I will try to set it up for a screen shot. The problem I have with AS is that I don't really know how to select alignment points (other than picking spots and clicking.) It seems very arbitrary. And, I don't know how to read the quality graph. Usually, I have better results with Registax simply because it is a program I am more familiar. And, understand the controls better. (I included the screenshot for the IR image above) Honestly, since I perceive no difference, it seems to be a waste of time to stack in one program, sharpen in another, (deconvolute in yet another, then, derotate in still another. My brain is over-loaded.) In good seeing, I can't tell from images which program was used to stack.
Steve, I use a Cool Edge fan system that goes in the secondary hole and holds the secondary, cooling the whole OTA and mirrors at the same time.
The tube went out at sundown. It was 72 degrees inside the house and 72 degrees outside at that time. About the next hour or 2 while setting up scope and other equipment, the Cool Edge is running and cooling the mirrors to the ambient temp outside. It only takes about an hour for temps to equilibrate. Temps did not drop rapidly that night. When it does, I set up the Cool Edge again and run it for about 20 minutes. But, each time I take the secondary out, I have to go through the procedure to check collimation. I waited til Jupiter was at meridian to start capturing, as I didn't want to have to swing the scope around for a meridian shift.
The last 3 sessions, I spent an hour getting Aldebaran on the screen, defocusing and looking at airy disk and adjusting collimation. This was the first of the last 3 times I set up and actually got video. Before that, I could satifactorily collimate. But, conditions and seeing are so bad, I folded up. So, taking 2 to 3 hours to diligently setup the scope and getting nothing for a majority of the sessions is frustrating. If I can't get some decent grabs right away, I don't sit out there hours, pushing buttons and being cold.
I wish I had it permanently mounted. That was the goal and still is. I think it would help shorten setup. And, eliminate a few problems.
