Notes

NGC 4236 in Draco is a seldom imaged object among amateur astronomers. Having an apparent size of over 20 arc-minutes and a very low surface brightness, this galaxy is a challenging object. Even with a high QE camera (ST-10XME) and a filter set with high light throughput, capturing the faint spiral arms of this galaxy proved difficult.

According to recent studies NGC 4236 is either a member of the local M81 Group of galaxies or is the largest member of its own small group consisting of itself, UGC 6456 and DDO 165. Either way it lies approximately 12 million light years from earth, being a not-to-distant neighbor of the Milky Way.
