John Herschel discovered NGC 1680 = h2668 on 28 Dec 1834 and recorded "eeF, R, resolvable, or else stars seen on it. Well defined (hazy)." His position (3 sweeps) is accurate.

300/350mm - 14" (4/7/16 - Coonabarabran, 178x): fairly faint, fairly small, elongated 5:3 WNW-ESE, 30"x18", even surface brightness. A mag 14.5 star is 25" S of center, just off the edge. A mag 10.5 star lies 8' WNW and a few mag 10/11 stars are in the field to the southwest.
