Steve's Notes

===== NGC 6058 18" (7/20/06): picked up at 115x as a mag 13-13.5 star surrounded by a small 20" halo. Adding an OIII filter the halo brightened significantly and increased slightly in size. Nice view at 225x as the central star and halo are both prominently displayed. At this magnification, the halo was slightly elongated NNW-SSE, roughly 25"x20" in size. At 325x, the planetary was beautifully framed within an isosceles triangle that just fits within the high power field of view. Adding a UHC filter the halo appeared irregular in surface brightness and dimmed around the periphery, perhaps extending to 30". 17.5" (5/27/00): fairly bright, fairly small, slightly elongated NNW-SSE, 25"x20". Contains an easy mag 13.5 central star which stands out well at all powers. At 380x, the halo appears to brighten surrounding the central star. Nicely framed within a triangle of mag 9-10 stars. 17.5" (5/30/92): fairly bright, small, 20" diameter. A bright mag 13 central star is easily visible. Located within a bright isosceles triangle consisting of mag 8.8 SAO 45874 4.8' NW, mag 8.7 SAO 45881 6.3' NE and a mag 10 star 3.5' S. 13.1" (7/5/83): fairly faint, small. Fairly easy central star at 166x, two stars to the north form an equilateral triangle. Can take 333x. 8" (7/5/83): at 100x, faint, very small, round, even surface brightness. At 200x, an extremely faint mag 13.5-14 central star is visible surrounded by a small faint halo. Two mag 9 stars to the north form an rough isosceles triangle.
