This was taken with my 11″ SCT, Hyperstar, ASI 294 MC Pro, and Optolong L-Pro filter to reduce light pollution.

The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy distanced 21 million light-years (six megaparsecs) away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain on March 27, 1781 and was communicated to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.
