My best efforts under these conditions lol. Had so many collimation and tilt issues with this scope, it's still not sorted fully but so far happy with how this image turned out. Thinking about adding more broadband data. SQM ranged from 16.3 to 16.7 (new moon) according to ASTAP. Not sure how accurate that is but seems to line up with what I see. It's a good thing M51 is bright!
