shot NGC 4656 (Halifax)

After a long run of clouds, the St Mary's University robotic telescope captured NGC 4656 for me. This is the luminance frame. Pretty significant gradient...

The Hockey Stick. In Canes Venatici. Sometimes it is called the Crowbar galaxy. A disturbed interacting galaxy. Lots of H II regions, it looks like.

RASC Finest NGC 4656 in luminance

Luminance, 60x10. FITS Liberator. Paint.NET. North is up; left is east.


Lots going on in this image...


Tried again on 25 Jan '18 without any improvement. Then again on 12 May '18--this one is better.
