Very nice - one of my favorite objects & difficult to capture - John
You've controlled the bright star well and the stars in this image are better processed than the ones in NGC7822. Try to remember what you did differently.
It does look a bit to me like this has been done with a non modified DSLR which I know is not the case, and come out rather blue. I am not sure how much data you can capture with a regular DSLR but you have done very well.

Leaps and bounds, going for the difficult ones now ;) The extra subs show in the lower noise and greater signal on the faint stuff - more is good!
Thanks everyone , on that blue Carol ,I've read up on this target and there is a massive blue star out of frame that casts that colour over the area.hence the blue nebula.

One of your best Roger...
You've done a good job of processing that one.
Another really tough target :)

Yes i think its my new favorite with M16 as a close second, since dithering and obviously proper flats i have had much better results
Thanks for all comments,
Roger
