Short Luminance of NGC 4038

Spent the first couple of hours last night collecting some good luminance in not so good seeing conditions (wasn't horrendous but not great), tried collecting an hour or so of RGB... After the first R frame the guider decided that it had done enough work for the evening and stopped guiding. With every frame thereafter having a very slow drift and visible PE, I do have a nice single Red frame but not quite enough to make an RGB image. As I'll probably have a new camera before I can get up to do any more imaging on this target, this will probably be as far as I go for a while.

1200s x4
900s x4
600s x1 (trying to make the most of time before meridian flip!)

Has an image scale of 1.5"/pixel and seeing of about 2.7". Processing probably still leaves a bit to be desired and there is clearly a bit of noise :/ Needs more luminance. Couple of galaxies in the background, no new ones sadly
