Steve's Notes

===== NGC 6741 24" (9/1/16): easily picked up at 200x as a very small, soft bluish glow. At 500x (unfiltered) the planetary appeared fairly bright, small, slightly elongated E-W, ~8"x6", brighter along the rim on the north side. There was no sign of a central star or any superimposed stars. A mag 13 star is 34" NW, a mag 14 star is 18" W and a mag 14.5 star is 25" SSW. Located 16' N of ·2434, a wide pair of mag 8.5 stars at 27" separation. 18" (8/25/06): picked up at 115x by blinking with an OIII filter. Appears light blue and soft at this magnification, making the identification as a planetary evident. At 323x a small, crisp-edged disc is fairly bright, ~8" diameter. Excellent view at 565x and the planetary appears slightly elongated ~E-W with a faint, very thin outer envelope with total size of ~10"x8". 17.5" (7/16/93): fairly bright, very small, round, clearly non-stellar at 220x, fairly high surface brightness, greenish tinge. Set in a rich field with several stars near including a mag 12 star 35" NNW, a mag 14 star 20" W and a mag 15 star 30" SW. A striking equal magnitude double star ·2434 = 8.5/8.5 at 24" is located 15' S. At 410x, the easily visible disc is slightly elongated ~E-W. The PN forms the SE corner of a rough parallelogram with three brighter mag 11-12 stars 2.7' N, 4' WSW and 4' WNW and several other faint stars are near. The planetary has an irregular surface brightness but no clear structure. Estimate V = 11.0-11.5.
