Description:
The bottom half of this planetary was fairly bright with a sharp border.  A
bright condensation was seen near the lower right edge.  A small area in the
center of the planetary was darker than the surrounding nebulousity.  No central
star was seen.  The upper half gradually faded in brightness until it blended
in with the background sky glow resulting in an indefinit border for the upper
half of the nebula.  No improvement was seen with the ultrablock filter.
