Constellation: Draco
Data: mag   size 
Position: RA 17:58  DEC +66:38
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.  This
object is not plotted in Sky Atlas 2000.  Can anyone tell me what this
object is?  I have observed ngc 6543 many times over the years and
never noticed any other nebulousity in the field.
