Corwin's Notes
=====
NGC 810. Stephan's position, given in both MNRAS and AN, is correct, but the
NGC position is 10 seconds west. This is one of the few transcription errors
that Dreyer made in his catalogues.
The galaxy itself appears to be triple on the blue DSS images: a close
dumbbell is oriented southwest-northeast, and a much fainter companion (or
jet?) is just east of the southwestern component. Stephan noted only one
object here, and the dumbbell is just barely noticeable on POSS1. On the
scans of the POSS2 plates, it looks more like a "polar dust ring" galaxy than
two interacting galaxies. It is clearly a single galaxy in the 2MASS images
-- only a single bright nucleus remains visible. The companion galaxy is also
well-seen in the 2MASS images, so this is a double interacting system.
