received NGC 891 data (Halifax)

Wow. Cool galaxy. BGO captured NGC 891 for me. This edge-on galaxy is in Andromeda (aka Caldwell 23). It is one of the RASC Finest NGCs. There's a bit of a gradient; not surprising given the moonlight.

RASC Finest galaxy NGC 891 luminance

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


On the east edge of the galaxy, slight above the bulge, there is something going on. An oval and a wisp. I suspect the oval is a background galaxy. Possibly it is a small satellite! But the wisp?! Dunno!

On the west edge of the bulge there is a bright round fuzzy. I wonder if this a large globular cluster or a large satellite galaxy to 891. Very neat.

At the bottom edge of the frame, to the south-south-east of the galaxy, is a distant oval galaxy. This  is PGC 9042.

Due south of the galaxy is a small round lint ball. This is LEDA 2194478.

In the image, I see another fuzzy near the aforementioned, below and right, or south-west. Slightly fainter. It is not identified by SkyTools.

The bright star is the bottom left is double ES 1501. I cannot split the A and B stars.

North-east of ES 1501 is a small round fuzz ball. Again, not identified in my software.


Tried again on 3 September but did not get a full data set.
