imaged NGC 7789 (Halifax)

The BGO robot imaged NGC 7789 for me. A big open cluster in Cassiopeia. One of the RASC Finest NGCs.

RASC Finest open cluster NGC 7789 luminance

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

North of the centre of the cluster is the double star STI 3065. ST3P shows the pair well away. But in the image, it's interesting. Perhaps it is a triple!

To the north-west is TDT 4287. I cannot split them.

South is a double star, according to SkyTools 3 Pro, STI 3063. It looks like A and/or B have moved.

To the east is STI 3067. Cannot split.

It seems to be there are a lot of other pairs in here...
