IC 1805, an emission nebula approximately 7,500 light years from Earth in the constellation Cassiopeia, is named the Heart Nebula due to its heart shaped appearance. The open star cluster Melotte 15 lies in the middle of the heart. The nebula is part of a large star forming complex in the Perseus arm of the Milky Way galaxy. The bright knot at the lower right (which some might liken to a male body part) is separately classified as NGC 896, and was the first part of IC 1805 to be discovered…

This one is a composite of 2.5 hours of H-alpha from my QHY9 CCD and 2 hours of RGB from my modified Canon XSi DSLR. Both through my William Optics 66mm triplet at f5.6. They didn't line up perfectly, but if you don't look to closely it's a reasonably nice blend of nebulosity from the h-alpha data and star colours from the RGB data. Framed it just for kicks.
