Description

This is a byproduct of my recent 41P shot. In the frame were not only dozens of small background galaxies, but also Winnecke 4, a double star system which was mistakenly held for a nebula by Charles Messier.

The Astrometry doesn't even annotate it.. It's the two near stars below the middle part.
