M101 (The Pinwheel galaxy): Four hours of LRGB/Ha data taken on the night of the 19th of April using a Sky-Watcher Esprit 80ED triplet refractor fitted within a field flattener using an ASI 533 MM Pro camera and mono filter wheel set. Data was integrated and processed in Pixinsight.
M101 is a face-on spiral galaxy 21 million light-years away from Earth in the constellation Ursa Major and is thought to contain a trillion stars. The Galaxy contains an abundance of H2 areas which have their own catalogue names in their own right; some of which were able to be resolved in the Ha captures. An annotation of the wide field image was done in Pixinsight, which shows the abundance of nearby galaxies in the field of view.
