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. Estimates of its distance from Earth vary from 35-60 million light-years.
Image data: L:R:G:B=610:230:230:230=21 hours 40 minutes total exposure at f/7.2.
