Planetary nebula |
h: "planetary, a most elegant and
delicate planetary nebula. Diam in RA = 1.35 seconds by many observations.
Long contemplated with x180, x240 and x320. The disc is magnified by the power
in due proportion. It is = a star 8.9 mag; perfectly sharp, not the slightest
haziness. A very fine object. It has no 'satellites'. My attendant, to whom I
showed it, said it was like the moon, only smaller, and not in the least like a
star." On a second occassion he called it "a clear round planetary
white disc, at most 4 arcseconds diameter. Has two stars 14th mag near; one at
dist 90 arcseconds, pos 108.8 degrees, the other dist 120 arcseconds, pos 60.2
degrees. See Fig 8, Pl.VI."
Steve Coe, observing with a 17.5" f/4.5
at 100X, notes: "Pretty bright, pretty small, somewhat elongated, green at
all powers, no hint of a central star even at 200X.
6-inch f/8.6 Newtonian: “This
soft, stellar, 10th magnitude glow is an easy starhop from any of several bright
stars that surround it (epsilon, lambda, pi, kappa, mu Lup). This colourless
disc looks just like a star in bad seeing. Examined with powers from 72x - 217x.”
