Steve's Notes

===== NGC 1514 48" (10/25/14): at 610x unfiltered; very bright and large; very irregular surface brightness, the rim varies greatly in thickness and brightness. The relatively thick rim is very bright in the northwest quadrant, along roughly a 70¡ arc. A second enhanced portion of the rim is along the southeast end (~35¡ arc) and a third slightly smaller, bright region (more circular) is on the east end. The rim is weak on the south or south-southwest end. A mag 17 star is at the edge of the rim on the southwest end. The rim is also weaker on the north and northeast side. The rim bulges out on the southeast side (near the two enhancements on this end) and to a lesser extent on the northwest end and the south end. The mag 9.5 star at the center and a very faint companion to its southeast are surrounded by a darker central hole. 18" (2/4/08): at 175x, appears as a large, roundish glow (~2.5'x2.2) surrounding a bright mag 9.4 central star. Excellent response to UHC and OIII filters. The surface brightness is clearly irregular with subtle brighter and darker regions. The SW and NE ends were slightly dimmer, while the NW and SE portions of the rim were brighter. The region around the central star was also slightly darker. 17.5" (12/30/99): at 100x, moderately bright, round, ~2' halo surrounding a prominent mag 9.5 star. Displayed an excellent response to UHC and OIII blinking while the H-beta filter killed the PN (OIII/H-beta = 12). Using the OIII filter, the surface brightness was noticeably uneven, with the NW quadrant of the rim clearly brighter. The SE end was also weakly enhanced while the center and ends of the minor axis were slightly darker. At 220x using a UHC filter, the halo appeared nearly 2.5' in diameter. There was a small, darker "hole" surrounding the central star and the halo was clearly irregular with a brighter "knot" on the SE side, while the NW portion of the halo was brighter along the rim. 17.5" (9/14/85): very bright, large, round, 2' diameter. Contains a very bright mag 9.5 central star surrounded by a fairly bright halo with an irregular surface brightness. Located midway between mag 8.3 SAO 57017 8' NNW and mag 9 SAO 57021 8' S. 13" (12/22/84): bright, fairly large, round, dominated by a mag 9.5 central star.
