IC 1805 is a young star cluster surrounded by Ha emitting nebulosity, located in the constellation Cassiopeia.  There is a great deal of interesting detail within IC 1805 that can be best appreciated in Ha light, as shown here in an image that I captured several years ago.  More information about this region can be found at Rob Gendler's website.
