Took a shot of M20 Luminance last night with the 145 (32*120s via a neb filter), got red and green set too but I ran out of time so this image is a combination - Luminance data from the 145 and colour data from my most recent shot on M20 with the 20D. I like the resolution I get with the 145 mono but the data collection and processing is a pain. Much to learn...but the detail I am getting is very pleasing.
