John Herschel discovered NGC 2145 = h2998 on 12 Nov 1836 and described as "F; lE; resolvable." His position from a single sweep is off by 1.7' in dec (too far south).

600/800mm - 25" (10/10/15 - OzSky): bright, fairly small, roundish, 40" diameter, well-defined slightly brighter core. A mag 14 star is at the southeast edge and two mag 15.5-16 stars are just off the north and east side. A bright mag 11.7 star is 50" SSW.
