M101

A nearby group of nine galaxies is dominated by the Northern Pinwheel, also known as M101. This enormous spiraling collection of stars, gas and, dust is located about 27 million light-years from Earth and spans over 170 thousand light-years from one side to the other. I captured this 16-hour exposure photograph over a two-year period through my 20-inch Ritchey-Chretien telescope and an 11-megapixel camera.
