Steve's Notes

===== NGC 6772 24" (8/30/16): at 225x and 375x (unfiltered); moderately bright and large, slightly elongated ~N-S, ~70"x55". The rim is slightly brighter, particularly along the east and west side and weaker on the south end. The surface brightness is irregular or mottled and there appeared to be a small knot [the DSS reveals two faint, very close stars] embedded on the northeast side. A mag 15.7 star is just off the east side [44" from center] and a mag 16.3 star is just off the north end [52" from center]. 18" (8/26/06): excellent view at 323x and UHC filter. Appears moderately bright, round, fairly large, ~60" diameter. The rim is sharply defined and slightly brighter with a subtly darker center giving a weak annular impression. 18" (8/23/03): at 215x with a UHC filter, this planetary appears as an irregular, 60" disc, slightly elongated N-S. The rim is slightly brighter, particularly along an arc from the southwest to the north side, giving a weakly annular appearance. At 538x the view is too dim but I noticed a couple of extremely faint stars along the edge of the rim. 17.5" (9/5/99): easily picked up at 100x as a 1' disc, appearing slightly irregular. Best view at 220x and 280x using a UHC filter. The disc was quite irregular in surface brightness and slightly elongated N-S. Most notably, the rim is generally brighter along the northern side in a broad "U" shape with the center weakly annular. The south rim of the planetary is fainter and less well defined. No central star seen at 380x. 13" (8/8/86): moderately bright, slightly elongated N-S, estimate V = 13.0. Pretty view at 214x and UHC filter with a slightly mottled or uneven surface brightness. 8" (7/31/81): faint, diffuse, moderately large.
