NGC7331

This spiral galaxy in Pegasus can be seen with small telescopes as a faint fuzzy spot. NGC 7331 was discovered by William Herschel in 1784. This galaxy is an unbarred spiral galaxy that is about 40 million light-years away from Earth. Other members are NGC 7335, NGC 7336, NGC 7337 and NGC 7340. The group is however not physical and only appears that way. The other members are between 294 and 332 million light-years away. The central bulge in a galaxy typically rotates with the disc of the galaxy but strangely in NGC 7331 this is the opposite. The galaxy is rich in HII regions that indicate star forming areas, much as in our own galaxy.

The image was taken from my home site with a Vixen VMC260 Cassegrain telescope and QSI583WSG camera on a Paramount ME2. To bring out the interstellar flux a very long exposure was needed.

Exposure times were: LRGB 35:8:7:7 hours.

All images were taken in 1x1 binning.
