I decided to try 1800" subs on this dim galaxy in Ursa Major. I've only seen it visually a couple of times, and it doesn't look like this in my relatively small scopes! This is 9x1800" through the 203mm Synta ONTC Newtonian at f/4.9 and an Astronomik CLS filter with the Atik 460EXC camera. Might be fun to go back next year and gather more data. This image benefited from Noise Exterminator.
