Spiral Galaxy in Aries

Uploaded 8/27/2001

When I first saw the black and white image of this object in the Vickers CCD atlas, I knew I would want to shoot this one in color someday. This beautiful spiral is in Aries, a little ventured part of the sky, and at magnitude 11.1, is bright for CCD standards. This class Sb spiral is 7x4 arcmins in size, and has a B-V index of .78, quite red for a galaxy. Few if any HII regions appear in the arms of this object, they are well below the required 2 seconds in size to resolve. This is also listed in Arps peculiar galaxies as number 78.
