NGC 1808 = ESO 305-008 = MCG -06-12-005 = LGG 127-002 = PGC 16779 05 07 42.3 -37 30 47 V = 9.9; Size 6.5x3.9; SB = 13.3; PA = 133d 13.1" (2/20/04 - Costa Rica): this 105x this striking starburst galaxy appeared bright, large, very elongated 4:1 NW-SE, 5'x1.3'. Sharply concentrated with a well-defined 20" core which brightens to a stellar nucleus. There appears to be an irregular extension at the NW end which brightens and is offset to the major axis [on photos this corresponds to a start of a spiral arm which is attached at the N edge of the NW end of the galaxy]. At 166x, the halo is irregular and mottled. Brightest in a group with N1792 40' SW. 17.5": bright, fairly large, small elongated core, long thin arms 4:1 NW-SE. A mag 14 star is off the NW end. This is a very pleasing galaxy. 8": fairly bright, elongated NW-SE, moderately large, bright core. | |||
