NGC 7331 is a large and bright spiral galaxy in Pegasus. At magnitude 9.4, it is easily visible in an 8" telescope. Associated with the galaxy are several smaller and fainter companion galaxies. Several of these are visible in a 10" telescope under dark skies. In the image above, just to the left of NGC 7331 is the 13th magnitude NGC 7335. Above it is NGC 7336 and below it is NGC 7337. To the left of NGC 7337 is NGC 7340.
For this image, a synthetic red-filter image was made by subtracting the green and blue images from an unfiltered image.
