Notes

IC 1613 is an irregular dwarf galaxy in the Local Group. It is approximately 2.3 million light years distant and is approaching the Milky Way at 235 km/sec. In 1928 Water Baade recognized this galaxy as a member of the Local Group because it could be resolved into individual stars using the Mount Wilson 100" reflecting telescope. Contrasting with this nearby galaxy, a sprinkling of much more distant galaxies can be found in the above image.

IC 1613 is rarely imaged by amateur astronomers. Because of its low surface brightness, even with sensitive CCD cameras it takes a somewhat long exposure to determine if it's in the field of view. This 4 hour total exposure does manage to bring it out from the background but not by much.
