Stephan's Quintet - Group of Interacting Galaxies in Pegasus

NGC7317, NGC7318A&B, NGC7319 & NGC7320

(RA 22h 36.1m, Dec. +3357', 13-14 mag., 1 arcmin. each)

This tight knot of galaxies is located 30' SW of NGC7331 group and about 4 NNW of h Pegasi (see finder chart below). Its core contains interacting galaxies NGC7320, NGC7318A, NGC7318B and NGC7319, while NGC7317 does not physically belong to the same group. Faint galaxy NGC7320C is also visible in the image.

The above image was taken on July 21, 1998 from Sooke, BC. Cookbook 245 LDC CCD camera was used on Ultima 8 f6.3 telescope autoguided with Cookbook 211 LDC camera on a piggybacked 500mm f8 telephoto lens. It is composed of white exposures (5 x 10 min.) as well as cyan, magenta and yellow-filtered integrations (3 x 4 min. each) combined with AIP4WIN. Color image was then adjusted in Lab color space using Corel PhotoPaint 8.
