This striking cloud of hydrogen lies in the eastern part of the constellation Cassiopeia and is part of a much larger nebula also known as IC 1805 or the Heart Nebula. This image is primarily glowing hydrogen and perhaps nitrogen. It was taken through a filter that records only those wavelengths. I hope to back for the glowing oxygen next week.
