Description:
This pn was fairly faint but responded very well to the Ultrablock filter. My
first impression with the filter in place was that this pn was almost square
rather than round. The central star was bright. The central area of
nebulousity was slightly dimmer than the outer bright ring. The outer ring
formed two arcs one of which went about half way around the nebula and the other
of which went about one third of the way around. On the side where the arcs
had the greatest separation the edges of the arcs were clearly concave. Part of
the central, inner, edge of the smaller arc also had a concave area. Faint
wisps of nebulousity extended off of each of the bright arcs helping to give
this nebula its squarish shape. A very faint star was seen immediately off the
edge of the larger arc. A drawing can be seen at
