17.5" (1/8/00): at 100x, this moderately bright PN was irregularly round, 1'
diameter, weakly annular with a faint glimpse of the central star. There was a
good contrast gain with the OIII filter and the image was crisp-edged, slightly
elongated SW-NE and the small, darker center was more evident. Excellent view
at 220x with the faint central star (mag 14.4) clearly visible. The surface
brightness was irregular with an unevenly brighter outer rim. The central star
was visible steadily at 280x and the overall surface brightness was mottled or
"clumpy" (brighter on W and NE rim), darkening in the center.
17.5" (9/14/85): bright, moderately large, almost round, 1' diameter, high
surface brightness. An easy mag 14.2 central star is visible. Appears darker
near the central star with a brighter rim.
13" (1/28/84): slightly annular, very faint mag 14 central star.
8": fairly faint, moderately large, bluish, slightly elongated, sharp-edged.
