2013/10/07 - I wanted to spend more time on this object, but weather isn't cooperating. This nebula is part of the Heart Nebula, but that object is too big for this field of view.

IC 1795 is an emission nebula located about 6,000 light-years away in the constellation Cassiopeia . It covers an area of about 20 arc minutes, which is approximately 70 light-years. This complex extends through the Perseus arm of our galaxy, the Milky Way, at about 6000 light years from us, near the double cluster and Heart nebula. It is easy to see and is in a rich environment with IC1805 and IC1848, as well as many open clusters.
