M100 is a beautiful face-on, spiral galaxy in Virgo. It is visible as an eliptical patch of light in an 8" telescope, while a 12" begins to show some spiral structure. Being part of the Virgo supercluster of galaxies, there are a number of faint galaxies visible in the photograph as well as M100. For example, just below M100 is the 13.2 magnitude edge-on spiral galaxy NGC 4312, while near the lower left cornor is a pair of 11th magnitude galaxies, NGC 4298 and NGC 4302.
At the time I took this image, there was a 17th magnitude supernova visible. The above image is reproduced below with a line is pointing to the supernova.
