returned to NGC 3521 (Halifax)

Commanded the BGO robot to photography NGC 3521 again. One of the first Finest NGCs I tried to image (back in March 2016).

spiral galaxy NGC 3521 in luminance

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


Different framing too. Using the new, smaller frame dimensions...


Tried again on 26 Feb. Possibly the best result.
