NGC 3081
48" (4/18/15): this beautiful resonant ring galaxy was viewed at 488x and 610x. It is very sharply concentrated with a very bright, roundish core (slightly oval at 610x) core that gradually increases to a stellar nucleus. The surface brightness drops significantly in the inner halo, but then brightens at the edge to a well defined oval ring, extending 5:3 WSW-ENE, 1.3'x0.8'. The ring is fairly narrow and brightens slightly at the ends of the major axis (southwest and northeast ends). This is a very distinctive object! The core itself contains a barred spiral ring, but this feature was not seen.
17.5" (3/28/87): moderately bright, fairly small, very bright compact core, possible stellar nucleus. The fainter oval halo is extended E-W.
