Lewis Swift discovered NGC 6560 = Sw. V-84 on 22 Oct 1886 and recorded "eeF; pS; iR; 5 stars near sf in a line, middle one double." His position is 1' too far northeast and the distinctive string of stars is 4'-5' east-southeast.
400/500mm - 17.5" (8/1/89): faint, small, slightly elongated SW-NE, low almost even surface brightness.
600/800mm - 24" (7/20/17): at 225x and 375x; moderately bright and large, oval 3:2 SW-NE, ~45"x30", broad concentration, small slightly brighter core. There is a strong suggestion of a spiral arm on the southeast side [galaxy is a bit "beefier" on this end], extending a short distance north. Situated 2' SW of a mag 10.4 star (with a companion at ~30") and two 10th magnitude stars lie 5' ESE.
