Steve's Notes

===== NGC 2276 48" (4/4/13): at 488x, NGC 2276 appeared fairly bright, fairly large, irregularly round, 2' diameter. Contains a very small, very bright nucleus, surrounded by a patchy halo with weak spiral structure. The most prominent arm winds along the western edge of the galaxy, curving from west to northwest and creating a very asymmetric appearance. Along this arm segment is a prominent knotty section with two or three clumps, including [HK83] 69, a bright 6" knot. On the southwest side of the halo is [HK83] 63, a faint 6" knot on a line between the nucleus and the 8th-magnitude star (HD 51141) 2.3' SW. In the brighter central region surrounding the nucleus are several brighter, small patches that define the inner arms. A slightly brighter region close southwest of the nucleus includes the multiple designations [HK83] 17/42/46/51. Finally, [H83] 24/27 are weak enhancements on the southeast side of the nucleus. HII region #24 was the site of SN 2005dl. 24" (9/15/12): moderately bright, fairly large, round, 2' diameter. Although spiral arms were not visible, the galaxy has an odd appearance with brighter knots and regions resolved. A non-stellar knot, identified in NED as NGC 2276:[HK83] 69 is visible at the NW edge. The central region contains a faint quasi-stellar nucleus, along with one or two other stellar knots including NGC 2276:[HK83] 24, close east of the nucleus. Another knot (nonstellar) is southwest of the nucleus (perhaps NGC 2276:[HK83] 63). The halo appears weaker on the east side and brighter on the west side. Located 2.3' ENE of a mag 8 star and it helps to move the star just outside the field. 18" (8/2/11): moderately bright, large, round, ~2.0' diameter, weak concentration, slightly brighter core. The halo has an irregular surface brightness giving a strong impression of spiral structure with slightly brighter knots on the west side. Located 2.3' ENE of mag 8.1 HD 51141, which hinders viewing and a mag 11.7 star is squeezed between the bright star and the galaxy. Brighter NGC 2300 lies 6' SE. These are the 3rd and 4th closest NGC galaxies to the North Celestial Pole. 18" (3/13/04): fairly faint, large, slightly elongated,~2.0'x1.6', low surface brightness. The halo fades gradually into the background, particularly on the eastern side, so it was difficult to determine a definite edge. Located 2.2' E of mag 8.4 SAO 1148 which detracts from viewing. Forms a trio with NGC 2300 6' SE and IC 455. 13.1" (1/18/85): diffuse, slightly elongated. Located 2.2' ENE of mag 8.4 SAO 1148 which interferes with viewing. Three mag 11 stars also in line with the 8.4 star to the south including a mag 11.5 star just 1.4' SW. Forms a pair with NGC 2300 6.4' ESE. 8" (1/1/84): faint, moderately large, low surface brightness, slightly elongated. A mag 9 star is near.
