Description

Aren't we lucky to get this awesome piece of space so close to us?

I previously listed as USNO-A2 0600-20212042 the tiny galaxy that I noticed in the top left. I scrolled over a tiny star on SKY-MAP.org and got that designation rather than the correct PGC 90239. I think the USNO-A2.0 survey is only stars?

Also another galaxy PGC 58355 is below Antares.
