Continuing on from Friday nights efforts, I got M8, M20 and M21 all into the field of view at once....
M8+M20+M21 in Ha - 10x1200s exposures - 3hrs 20mins.
The following picture uses M8 data from Friday and Saturday nights, This contains 18x1200sec exposures in Ha, and 24x300sec OSC exposures.. a total of 8 hours exposure. This is my longest exposure image to date.. Im still not 100% happy with it.. I will be much happier when I can get some fresh colour data with a matching focal length..
