While waiting for an asteroid to come into view, I had enough time to image a target of opportunity. NGC 7331 is a large spiral galaxy located in the constellation Pegasus. As is normally the case, there are several other galaxies visible as well. Just starting to become visible in this image assembled from thirty-one 60 second exposures are three other members of the “NGC 7331 group” (NGC 7337/7335/7336). Although visually close, all the galaxies lie extremely far from each other and only look close from Earth’s perspective.

This image shows a spiral galaxy centered in a sparce field of Milky Way stars. It is slightly tipped towards the observer with the near edge lower. There are sveral other but much cmaller, more distant galaxies.

In the constellation map, NGC 7331 lies at the ‘top’ of Pegasus bordering on the constellation Lacerta (the Lizard).

This is a map of a portion of the northern celestial sphere. The constellation is highlited with the brighter stars connected by lines.
