NGC/IC Project Restoration Effort

===== NGC 6818. See NGC 6822 = IC 4895.

===== NGC 6818 18" (7/23/06): this very high surface brightness blue planetary takes high magnification well and 565x provided an excellent view. Appears slightly elongated N-S, ~20"x15". Most striking is an annular structure with a brighter rim and darker center. The rim has an irregular surface brightness and is brighter along the southeast and east side. Although the contrast of rim and darker center is fairly low, the relative thickness of the rim is comparable to M57. Barnard's Galaxy lies just 40' S. 17.5" (7/12/99): at 100x this striking PN is bright and small with an obvious blue color. The high surface brightness easily allows high power. At 380x, there is subtle but obvious structure with a darker center and an irregular brightness to the halo. Most noticeably the PN is brighter on the east end and mildly annular. Appears slightly elongated N-S, ~20"x15" in size. Three mag 13-13.5 stars are nearby at 40" NW, 1.0' E and 1.3' SW. 17.5" (7/16/88): at 412x appears very bright, fairly small, slightly elongated N-S, blue color, very high surface brightness. Appears brighter along the east side and slightly brighter along the west side compared to the center. Has a darker elongated center but the annularity has a pretty low contrast. Barnard's galaxy NGC 6822 lies 40' SSE. 13" (9/3/83): very bright, slightly elongated N-S, fairly small.
