shot NGC 869 again (Halifax)

I asked the BGO robot to shoot NGC 869 for me again (after the partial run on 21 August). Better quality, in general. One half of Caldwell 14; one half of the Double Cluster.

RASC Finest open cluster NGC 869 luminance

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