05 27.5 -12 42
17.5 (3/8/97): unusually bright mag 10.5 central star surrounded by a small
high surface brightness halo. At 220x, this planetary has a distinct
"blinking" effect; staring at central star partially washes out the halo
and with averted the halo is more dominant. At 82x, an unusual rosy tinge
is evident at the edge of the small halo, although the effect is fairly
subdued. See not good enough for high power viewing of outer shell.
17.5: high surface brightness planetary which appears very bright at 481x.
Contains a bright "fuzzy" central star with a bright inner portion
surrounded by a second fainter shell slightly elongated N-S.
13: very bright, small, takes 350-410x well, bright central star, subtle
shell structure.
8: nearly stellar at 100x, bright, appears as a mag 10 star with a small,
faint bluish halo.

17.5: at 220x and OIII filter; very faint, small, about 10" diameter,
round. Visible continuously with averted vision and almost continuously
with direct, estimate V = 15.0-15.4. OIII filter improves visibility over
UHC. A mag 11 star lies 1.2' SSW. Located 4.8' SW of mag 8.6 SAO 77228.
K3_68, RA 05,31.6 DEC +28,59 MAG 16.1 CSM ? SIZE 10" on 04/21/98. At 134X & 169X, faint unsteady disk requiring the O-III filter and averted vision. Fair response to the O-III & UHC filters. No response to the H-B filter. At 254X, could see a hint of the PN with averted vision alone but needed the O-III filter to identify it as the PN. Identified the field in the SEC finderchart.

17.5: at 105x, slightly non-stellar without filter. Using an OIII filter
appears as a moderately bright, small disk. At 220x, a small halo
surrounds the mag 14 central star without a filter. Using a Daystar 300
filter this planetary appears prominent, fairly small, probably slightly
elongated. A string of stars begins about 4' E and extends to the NE
including three mag 9 stars SAO 94762 10'NE, SAO 94766 14' NE and SAO 94775

noticeable contrast gain with UHC filter. Position verified on P-K finder

lack of contrast gain with filters due to low OIII emission. Located 12' S

V = 12.5; Size 37"
17.5" (11/6/99): At 100x and OIII filter Abell 12 is easily visible as a
round knot bulging off the NW edge of mag 4 Mu Orionis (3 degrees NE of
Betelgeuse). Nice view at 280x with a UHC filter. The PN is fairly
well-defined, ~30" in diameter and just resolved from Mu although glare from
the star is very distracting. At 380x, Abell 12 is now fairly well separated
from the glare although not crisp-edged.
17.5": at 220x and UHC filter; moderately bright, round, moderately large.
Difficult to view as overpowered by glow of mag 4.1 Mu Orionis 1.2' WNW!
Easier at 294x which cleanly separates the pair, estimate V = 12. Takes 412x

lengthened on an axis N - S. But one does not perceive condensations . ( 14/02/98 T=3 S=2

MAG 15.9 SIZE stellar on 02/01/00. At 169X and 254X, can see as a faint
star with averted vision alone but required the H-B filter to identify it as
a PN. The H-B filter makes the faint star brighten when using averted
vision. Fair response to the H-B & UHC filters. No response to
the O-III
filter. Identified the field in the SEC finderchart.

At 254X, it was extremely
faint requiring the UHC filter and averted vision. Response to the O-III filter
is less than the response to the UHC filter and there is no response to the H-B
filter. I was only able to find this one because I identified the field in the
SEC finderchart. This is a first known visual sighting. Kent

Mag=11.8 Size = 82"; on 01/10/99. At 62.5X can see with averted vision alone as a
fair sized disk but initially needed the O-III filters to identify it. Good response
to the O-III and UHC filters. No response to the H-B filter. At 100X & 200X there is a
faint star involved with the edge of the PN. No central star is visible. This is a

At 169X and 254X the PN was still stellar. Identified the field in the SEC

17.5": very unusual appearance at 380x with two bright knots oriented SW-NE
about 30" between centers. The SW knot is 15"-20" in size, slightly
elongated and the brighter of the two. The NE condensation has a slightly
lower surface brightness and appears ~20" in diameter. Symmetrically placed
between the knots is a faint 14th magnitude central star. Weaker nebulosity
connects the two knots giving a dogbone appearance and a faint rounder halo
encases the structure.
17.5": unusual planetary, bright, moderately large, elongated SW-NE. Two
bright knots are at both ends (with two NGC designations) although the SW end
is brighter and concentrated.

17.5" (1/9/99): the Medusa Nebula is a striking, huge planetary at 100x using
an OIII filter! The thick ~10' crescent shape is bowed out to the east and
incomplete on the preceding side. The rim is generally brighter and locally
brighter at the SW end of the rim. The surface brightness is irregular along
the rim with the inner edge dimming towards the center and increasing in size
with averted vision. Several stars are superimposed with the brightest star
on the NE side. Faintly visible without a filter. Easy with averted vision
in 80mm at 21x using an OIII filter.
17.5" (2/8/91): at 100x and OIII filter the "Medusa Nebula" appears
moderately bright, very large with a distinctive thick "horseshoe" shape open

incomplete on the W and NW side. A brighter star is embedded in the NE
portion of the rim.
