Contemporary Visual Observation(s) for NGC 253
NGC 0253 = ESO 474-G29 = MCG -04-03-009 = UGCA 13 = Sculptor galaxy = PGC 02789 00 47 33.1 -25 17 17 V = 7.2; Size 27.5x6.8; SB = 12.7; PA = 52d 17.5" (8/29/92): very bright, very large, edge-on 6:1 SW-NE, 30'x5', possibly 35' length at 100x. Remarkable dust structure and mottling visible particularly on the SW extension and a dark lane runs along the north side. On the SW extension three faint HII knots are visible near an embedded star; just SW and a bit further NW of the star and a slightly brighter knot to the NE of a star near the core. The galaxy exhibits only a weak central concentration to a small elongated core slightly larger than the knots. Several stars are superimposed on the galaxy. 13" (9/11/82): very bright, elongated 4:1 SW-NE, very mottled, dust lanes, dark patches, 30' diameter. 8": very bright, very elongated, mottled, 25'-30' diameter. - by Steve Gottlieb
