Messier 101 - the pinwheel galaxy
This is an image comprising of 35 subs at 8 minutes (480 seconds) each. I am amazed at how many subs I had to take in order to get significant detail - I can just about see the faint galaxy arm on the right, which I would have loved to have captured more fully. Admittedly, on examination, even though the sky was clear 'on the eye', the last 5 subs of the run had a lot more detail than the other 30 - so I may well have got a far better detailed image had all of them been the same as these. The initial 30 were not particularly good either with a lot of variance between them. Once again it has been a struggle to process the background. I am at the limit of my skies and having assessed my light pollution using the Bortle Scale, I believe I am at about the worse level of 8-9. I used the Atik 4120EX for this with my Skywatcher 8" f4 Quattro.
