17.5" (7/11/99): at lower powers appears moderately bright, irregularly round,
~1' diameter with several stars involved or nearby. At 280x, the view is very
unusual with three stars involved and others nearby. The brightest is a mag
12.5-13 star at the NE edge. The mag 13.5-14 central star is visible with
direct vision. Finally, a mag 14.5-15 star is at or just off the west side.
The planetary is slightly elongated 4:3 SW-NE with an irregular surface
brightness. The rim appears brighter along the E and NE side and weakest at the
west edge. Nearby stars include a mag 13 star ~1.5' NE (nearly on a line with
the central star and the star on the NE edge) and a mag 15-15.5 star close SSW
of the star at the west edge.
13": moderately bright, elongated WSW-ENE. Unusual appearance as four faint
stars are very near or involved including the faint mag 14 central star visible
with averted vision. A mag 13 star is at the NE edge 27" from the center, a
very faint mag 15 star is at W edge and a similar star is just NW. The rim is
possibly slightly brighter on the E edge.
