Yooouuuuu're baaaaaack!
Lovely image Mike! For a NB image that is
... I like the colours you've mapped - very appealing.
Yeah - I reckon you need to ditch the guidescope so you can go for longer subs. You'd make some
really deep images from a dark sky!
In spite of Gregs comments I'm not sure your stars are as tight as they could be given the image scale (?) Was the seeing a bit off? Maybe a bit of decon needed? Their shape looks dead on though. If anything only a slight probs at the corners but not worth worrying about IMO.
Cheers, Marcus
