Steve's Notes

===== NGC 7094 24" (8/31/16): excellent view at 200x using an NPB filter. The 90" disc is fairly crisply defined and contains the bright central star (mag 13.5), even with the filter. Unfiltered, a mag 14.5-15 star is at the NE edge. The planetary is weakly annular and brighter in a 90¡ arc along the west side. There appears to be a knot or local brightening right at the west edge of the rim. The compact galaxy II Zw 141 lies 6' WNW. It was seen as faint, very small, round, 12" diameter. On the DSS a mag 15.2 star is at the southwest edge (6" separation from the center of II Zw 141) and probably the galaxy + star were merged visually. 18" (10/9/04): picked up at 73x using the OIII filter as a fairly faint, round, evenly lit 90" disc. Good contrast gain with the filter. Faintly visible unfiltered at 160x as a moderately large but low surface brightness halo surrounding the 13.5 magnitude central star. A faint mag 14.5 star is at the NE edge of the halo. A string of 3 mag 14-15 stars oriented NW to SE lies ~2' NE. Images show the a complex multi-rim structure (brighter along the west side) with a darker center, but visually the planetary appeared pretty featureless. Located 7' S of a mag 10 star (SAO 107277). 17.5" (10/2/99): at 100x and OIII filter appears fairly faint, round, moderately large, 1.5' diameter, even glow. At 220x without filter, the central star is easily visible surrounded by a round, low surface brightness glow. A very faint star is at the NE edge. No annularity seen. 13" (6/18/85): at 62x with filter appears faint, moderately large, round. Without a filter the faint mag 13.7 central star is visible surrounded by a very low even surface brightness halo 1.5' in diameter.
