NGC 3100
48" (5/12/12): very bright, fairly large, oval 5:3 NNW-SSE, ~2.0'x1.2', sharply concentrated with a very bright oval core that gradually increases to the center. Three stars are close following; two mag 10.5/12 stars 1.3' E and 1.5' SE, with a closer mag 14 star 0.9' SE of center. We took a look at NGC 3100 because an uncatalogued companion (not found in NED or HyperLeda) is just 0.9' SE. At 488x the companion was easily visible and appeared fairly faint, small, very elongated 3:1 SW-NE, ~21"x7", situated just north of the mag 14 star.
17.5" (3/28/87): moderately bright, small, round, bright core. Two mag 10/11.5 stars are 1.3' E and 1.5' SE (30" separation N-S). NGC 3095 lies 11' NW and NGC 3108 23' E.
