Steve's Notes

===== NGC 6879 24" (9/2/16): picked up at 200x unfiltered as a slightly soft, pale blue "star". Excellent response to an OIII filter. A slightly brighter 12th mag star is 1.4' SW, though with the filter the planetary dominates this star. Improved view at 286x and 375x. A small 5" disc is easily resolved. Nearby a mag 13.5 star is 50" WNW and a mag 14 star 50" SSE. At 500x, a 15-15.5 mag star is just off the north side (15" separation) and another 15th mag star is 30" SSE. The center is brighter but the seeing wasn't steady enough to resolve the central star. 17.5" (9/5/99): picked up at 100x with OIII blinking as a mag 12 "star" by star hopping from the double star ·2634 = 7.9/9.4 at 5" which is 14' SW. A good comparison star for blinking is situated just 1.5' SW. At 280x, the PN has a slight bluish tinge with a "soft" edge. At 380x, a very disc ~4" is resolved with a brighter center. The disc is easier at 500x and a mag 16 star is occasionally visible at the north edge. 13" (7/85): observation from El Cerrito: stellar planetary at all powers, confirmed by OIII blinking, estimate V = 12.0. A similar mag 12 star is 1.4' SW. Located 14' NE of ·2634 = 7.9/9.4 at 5".
