Dust and the NGC 7771 Group
http://apod.nasa.gov/apod/ap100121.html
In this picture are several galaxies in the direction of Pegasus. The NGC 7771 Group and NGC 7769 are the most easily visible. The NGC 7771 Group includes several galaxies, one of which is the spiral galaxy in the center. NGC 7769 appears to be the largest galaxy in the picture and is also a spiral galaxy. The NGC 7771 galaxies may eventually merge because they are passing by each other at small distances. This is suggested by distortions and small streaks of stars in the galaxies. Large clouds of dust are also visible in the picture.
