Had a tough time getting enough exposure on this object ... between the the time change, hazy moonlit skies and clouds, finally got enough for this image. Also see the NGC 3917 Galaxy group, just 39 minutes WSW ... UGC 6840 (2.3' x 1.9'; mag 14.3b, Cl: SB(rs)m) is at the WSW (lower right) of this image, and is also in the NGC 3917 group image.
