M101
M101 is a beautiful spiral galaxy seen face-on in the constellation of Ursa Major. Its apparent size is nearly a full Moon, but its extent and fine spiral arms can only be observed through a large telescope.
It is 27 million light-years away and is the brightest in a group of at least 9 galaxies.
Photographed by "baf" (the person's pseudonym on the astro forum) using a digital reflex camera fitted behind a 150 mm diameter telescope.
