Thanks Bob
Yes it was taken at f2.8 in my backyard at Modbury North.
Iv probably taken 300+ shots over the past month or so, all at different times, settings etc and all with darks and bias frames and put in Deep Sky Stacker. Still not coming out as good as I would like.
I must say though I have 60sec+ shots at 200mm and the Star Adventurer tracks beautifully. I use a $30 Ebay Intervalometer. Could never get my head around the inbuilt one.
I will try f4 though. I know what coma is but whats CA?
Cheers
Mike
