10x30mm Canon IS (3/28/19 - Tasmania): faint, small, roundish, no obvious resolution. Not difficult to identify just northeast of the "False Cross".

John Herschel discovered NGC 2910 = h3171 on 10 Apr 1834 and recorded "Cluster of loose stars; p rich; stars 11...15m; has rather a vacancy in the middle; fills about 2/3 of field." On a later sweep (763) he measured an accurate position on a bright star at the southeast side of the cluster.

400/500mm - 18" (7/8/02 - Magellan Observatory, Australia): ~50 stars are resolved in an oval or "racetrack" outline oriented NW-SE, perhaps 6'x4', with outliers making the group rounder. Includes a half-dozen stars brighter than mag 11. The SE end of the oval has a rich subgroup over unresolved haze. No concentration, in fact the center of the "racetrack" is nearly devoid of stars!
