Steve's Notes

===== NGC 6765 18" (7/16/07): this unusual planetary was picked up at 174x unfiltered as an elongated glow. The view is confused, though, as a star or knot in directly involved at the NE end along with 1 or 2 additional stars around the edges. Excellent contrast gain with an OIII filter as the edges sharpened up and the halo appeared elongated 2:1 SW-NE, ~0.6'x0.3'. At 225x, a mag 14-15 star is just off the NE end and the involved knot seemed to occasionally resolve into a couple of faint stars just north of center near the NE edge. Finally, an extremely faint star occasionally sparkled at the SW end. 17.5" (9/5/99): picked up at 100x as a small, irregular glow in a rich star field by moving 20' NW of ·2483 = 7.9/9.0 at 10". At 220x, the PN is clearly elongated ~2:1 SW-NE. The appearance is odd with a much brighter NE end and a fainter extension to the SW end. A mag 14.5-15 star is just off the NE end in the direction of the elongation. At 380x, a very faint star was intermittently glimpsed within the NE end. If this is the central star it is very eccentrically placed. 13" (6/18/85): faint, elongated SSW-NNE, appears similar to a diffuse galaxy. A faint mag 14.5 star is at the NE tip. Located 20' NW of ·2483 = 7.9/9.0 at 10".
