John Herschel discovered NGC 2137 = h2994 on 23 Dec 1834 and recorded "vF; R; 30"; the following of 2 [with NGC 2136]." His position (2 sweeps) is accurate.

600/800mm - 30" (10/13/15 - OzSky): at 394x; moderately bright, small, round, 20" diameter, lively, several extremely faint mag 16+ stars resolved. A mag 13 star is 50" NE. NGC 2137 is the fainter and smaller of a striking double cluster with much brighter NGC 2136 just 1.4' SW!
