Burnham
writes “This is a fine PN, easily located 1.8”deg south of star Mu Hydrae. In
the small telescope it shows as a pale bluish disc about 40” x
35”, appearing like a “Ghost of Jupiter”. The total magnitude is about 9; the
central star is 11.4 visually.
Several logs of this PN were
merged in a coloured sketch on black paper. “Ghost” is one of the most complex
PNe I've attempted. It has at least four distinct parts:
Outer Halo. Almost circular
but faint, maybe 20% the brightness of the central
Ellipse. The Ellipse. This is a bright shape three times
longer than its width – and fits neatly in the Halo. Inside this is the Iris: an almost circular ring, at least twice as
bright as the Ellipse. A star-like 'thing' lies at the E end of the Iris. The central star was not seen but another 'thing' might lie at the W end. More work needed!
