NGC 7331, NGC 7320
Spiral Galaxy and Stephans Quintet in Pegasus
NGC 7331 in Pegasus
This spiral galaxy is often cited as being very similar to the our own Milky Way and what it might look like from intergalactic space.
NGC7331 contains the mass of about 140 billion Suns and lies at a distance of about 50 million light years or about 20 times farther than the Great Andromeda Galaxy.

Large field photographs of NGC 7331 include an interesting cluster of galaxies better known by the group name than by their catalog numbers.
NGC 7331 and Stephan's Quintet
This photo contains a large galaxy (NGC7331) in the lower left that is relatively near to our Local Group of galaxies. It also contains a group of very remote galaxies (Stephan's Quintet) similar to our Local Group.
Stephens Quintet is/are the fuzzballs in the upper right. Actually, 12 galaxies can be counted on the negative.

Stephan's Quintet in Pegasus
This group was once the center of a raging controversy. Seems that one of the members appears to be much closer than the others but shows evidence of interacting with one of the more distant members. This would imply that something is fundamentally wrong with the way we measure extragalactic distances.
