Description: NGC 6543 and IC 4677 (large and faint
at mag. 15.7) My notes from March
1998 read as follows: NGC 6543 was bright blue
green at lower powers, turning mostly
green at higher powers. The central star was easily
visible. The oval shape was obvious
at all powers but at 390x the southern edge was seen
to be irregular with a comma shaped
projection. Of interest was a dim, diffuse, hazy
patch of nebulousity about 60 seconds
west of ngc 6543. The nebulousity was about twice
the diameter of the planetary. It was
near the apex of a triangle of dim stars and about two
thirds of the way to the nearest
bright field star to the west of ngc 6543.
7-10-99 This
object turned out to be IC 4677. On this night I not only noticed
the
comma shaped projection but also a cap on the opposite
side of the central round area of
nebulousity of ngc 6543. E.E.
