NGC2403
Page published 2010-11-27
Galaxy NGC2403. Imaging session cut short, and I’m not happy with the results – insufficient subs for good s/n ratio, contrast was low due to collecting thin cloud and I think I should have used longer subs to tease out more internal detail. Will try again another time.
