Yes Grant, the camera uses a Peltier cooling system for the chip.Quote:

I see some 'fiddle' with the image before stacking and others saying the manipulation should only be done afterwards. I get the how and why you stack it's just the know how to get to the final image that seems the difficult part?!
How long do you spend on the PC after collecting all the images you want?

It's definitely a game of two halves Paul. The processing is just as big a source of frustration and learning as the capture.
I have used Deep Sky Stacker before but my preference is Astro Pixel Processor, which IMHO give much better control over the process and better results, albeit with a quite intimidating user interface. Having said that, it is set up so that it's defaults give good results and there are plenty of video tutorials available.
After stacking or integration, the processing side is generally split into two camps, Pixinsight and Photoshop, although some imagers use both to some extent. Pixinsight is designed by and for astroimagers but has a steep learning curve, Photoshop, some would argue, has more a more comprehensive toolset and flexibility. It's entirely subjective in my view, use the tools you are most comfortable with. I'm under no delusion that what I am doing is scientific, I'm (hopefully) making pretty pictures and will use whatever assists in that endeavour. :-)
Generally it will take me between 1/2 to 1 full day to process an image, depending on the complexity (single image or combined integration).
There are a lot of similarities with Hifi, I've found. Objectivists and Subjectivists, the constant need to purchase more kit, the constant disatisfaction with the end result. :doh:

Have you ever thought of selling some of your astrophotographs as prints? I'm sure there would be some who would love to have them up on the walls.
I’d given it some superficial thought Barry but wasn’t really sure how much of a pain it would be right now. Certainly happy to provide the odd prints (preferably acrylic as they’re the best value I think) at a nominal admin cost if anyone is interested?Quote:

This is The Wall (to be said in a Danny Dyer voice) in Cygnus, processed in the SHO (Hubble palette).

Cheers!
This is actually a composite of a two hour 'narrowband' image capturing Hydorgen Alpha and Oxygen III, together with the stars extracted from a normal 1 hour RGB capture.
I still haven't sorted it properly yet, as I went 'snowblind' processing it last night :-)
