IC342

This is a hard object for me. A galaxy in the local group. It’s fairly big, but very low surface brightness. And the light pollution in backyard is high enough that I cannot get a decent data set to build a good image. This exposure consists of 20x10 min light and 20x10 min darks. 150x10 sec darks and dark flats (although they may not be that good). In this exposure run I was plagued by field rotation and it was hard to align the images and retain the information. Hence you see the left is lighter than the right. In fact I did another exposure set with 4x30 mins and it turned out to have too much noise.
