Description

This is a polar ring galaxy, a fairly unusual type.

The night of February 23rd started out great, with excellent seeing. Unfortunately, I found when processing that subs from the 2nd half of the night were unusable due to clouds moving in and out. Still, the 190 minutes of data still contains a lot of detail and goes reasonably deep.

Version A is annotated in PixInsight.

Version B is full size.

Version C is cropped to 800x600.
