NGC 5033 is a beautiful spiral galaxy in the Constellation Canes Venatici. It is difficult to image because, despite its very bright nucleus, it has incredibly faint spiral arms that require long exposures. Warping of the disk and spiral arm streamers indicates it had a "recent" interaction with another galaxy. Estimates of its distance from Earth vary from 35-60 million light-years. Exposures: L:R:G:B=610:230:230:230=21 hours 40 minutes total exposure at f/7.5.
