Description

This was a major undertaking for me - a big risk, really. Doing this at f12 with 2 minute subs, with a difficult sky and disproportionate amount of Ha and OIII data, made this very tough. I have done what I can with the data, and even though I took a number of 15s subs for the core, the stacker could not stack them due to how faint the stars were at that exposure time. So, 42 Has and 135 OIIIs all at 2 minutes exposure time - thus 5 hours and 54 minutes imaging time. Don't look too closely!  :   )   Thanks everyone...
