captured NGC 7331 (Halifax)

The BGO robot imaged NGC 7331 for me. A galaxy in Pegasus. One of the RASC Finest NGCs. A lovely canted spiral galaxy, also referred to as Caldwell 30. Huge. Amazing structure. Had to clip the whites to draw out the neighbouring galaxies.

RASC Finest galaxy NGC 7331 luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; left is east.


There's a small canted spiral at the 10 o'clock position. That's NGC 7335.

Beyond it a tiny round fuzz ball. NGC 7336.

Due east is round bright object. NGC 7340.

At the 8'clock position there's a small round, slightly oval, fuzzy right beside a star. NGC 7337. SkyTools does not show the star.

At the top-right of the image is a faint small canted spiral. NGC 7326.

[ed: Curiously, NGC 7325 is not visible. Assuming SkyTools is right, it should be between the main target and 7326. ST3P shows it is larger and quotes the magnitude as 14.9. ST3P shows a bright star here, GSC 02743-2056. Something is odd about that star, if you zoom in. It looks fuzzy on its left edge...]
