NGC 4102: Galaxy (Ursa Major) RA: 12h 06.4m / DEC: +52° 42'.7 Instrument: 10-inch Starfinder |
This little stinker resides about 2 degrees southeast of 2.4 magnitude Gamma (64) Ursae Majoris. NGC 4102 presents as a 2'x1' profile at 82X in my 10-inch Newtonian reflector. As shown in the sketch at left, this Sb-type spiral features an impressively bright stellar core. The galaxy is book ended by 12th and 13th magnitude GSC stars. The 7.9 magnitude star halfway between NGC 4102 and the northwest field boundary is HD 105030. |
