Description

Here is my image of ngc 3359, a most attractive, delicate face-on spiral in UMa. Imaged under somewhat difficult conditions (intense cold, freezing East wind and a half moon), this turned out quite well really considering. I was not expecting to get anything as I had so many trailed images due to the strong wind. This is only 39 minutes exposure - I didn't really have enough to sigma combine so this is an average combined image. I had to spend some time getting rid of the 'hot' pixels manually. Still, a nice galaxy that will definitely repay more attention on a better night.
