Two too brief periods of clear sky allowed me to collect luminance

Blinking the frames I selected for use was quite interesting as it
showed the frequent and rapid changes in both seeing and transparencey
that occur duiring the winter season. I was able to use about 60% of
the collected frames.

NGC 2146 is a star burst galaxy still experiencing the effects of a
collision or close encounter with NGC 2146a some tens of millions of
years ago. NGC 2146 is classified SBa-b/P, Surface brightness is
12.8 and red shift distance is 41 Mly.


Nice close up of it.

That's one I'd like to do. How Arp missed it I don't know.
Unfortunately, at 78 degrees it is well into my Polaris tree and thus
out of reach. Sigh...
