V = 13.8; Size 22"x20"
17.5" (7/22/00): visible unfiltered at 220x as a fairly small disc,
~20"
diameter with several faint stars nearby. Best view at 2x0x using a UHC
filter; fairly faint, round, crisp-edge to disc, smooth surface brightness.
Removing the filter, a faint star is at the south edge (with a companion
close SE) and a dimmer star is at the east edge of the planetary. Located
1.25° south of IC 1295/K4-8.
K4_8 = PK 25-4.1
18 54.4 -08 48
17.5: at 105x and 220x appears as a stellar planetary, estimate V =
13.5-14.0. Responds well to OIII and Daystar 300 filter. Located just
4.6' WNW of planetary IC 1295 and 22' SE of globular cluster N6712!
Situated within a close arc of four similar faint stars.
13: verified with UHC blink at 214x. Appears as third "star" in a close
arc of four or five stars, estimate V = 14.0.
V = 14.2; Size Stellar
17.5" (7/22/00): this stellar planetary is situated just 5' WNW of IC 1295!
At 140x, visible as a mag 14.5 "star" in the middle of a shallow of
arc of 4
stars, concave to the north with a slightly brighter star is at the east
edge. Excellent contrast gain with OIII blinking and K4-8 appears to "turn
on" and becomes brighter than the star on the east end.

13: the rim on the S or SW side appears brighter but no definite annularity
seen.

V = 12.5; Size 102"x87"
Fairly bright at 220x using a UHC filter as a roundish disc, ~1.6'x1.4'. The
surface brightness is irregular and it appears slightly brighter along the SW
and NW portion of the rim. The unfiltered view at 280x also reveals a mottled
appearance with a mag 13.5-14 star situated right at the west edge and a mag
14.5 star in the interior (a bit offset from center). A couple of extremely
faint stars are at the following edge.

18 55.5 -21 49.6 July 20, 1998 Steve Gottlieb
17.5" Y-C 2-32 is a little known 14th magnitude stellar planetary in Sagittarius
which escaped discovery until 1973. Situated close to the ecliptic at 18
55 30.7 -21 49 40 (J2000), it's not plotted on the Uranometria but was
identified at 220x using a GSC finder chart of the field. It appeared as a
mag 14 "star" just 1.1' WNW of a mag 12.5 star. Using the OIII
"blinking"
method, the object was immediately identified at 140x as a planetary due to
its excellent contrast gain as the planetary appears significantly brighter
than the star close following (gain of ~3 magnitudes). The image was
completely stellar at 280x.

RA 18,55.5 DEC -21,50 MAG 13.3 SIZE 15" CON Sgr SKY 22 URA 340 MILL 1390
This PN was discovered by C.U. Cesco & J. Gibson in 1973.
Field Description: At 62.5X, stellar, requiring the O-III filter and averted
vision. Fair response to the O-III & UHC filters. No response to
the H-B filter. A faint star can be seen to the east of the PN. At
100X and 200X, the PN can be seen with averted vision alone as a faint star,
requiring the UHC filter to identify it as a PN. Identified the field in
the SEC finderchart.

13: a faint stellar object was visible near or at the position on the P-K
finder chart (estimate V = 14.5-15.0) but demonstrated no response using
UHC, OIII or Hß filters. Probably viewed a field star or possibly the mag
14.9 central star. ESO-Strausberg catalogue shows very weak OIII emission.

Did locate the star shown to be the PN in the SEC finderchart but it had no response to any filter. Perhaps the central star hides the nebula.

At 134X, stellar,
relatively bright for a MAG 16.9 PN, requiring the O-III filter and averted
vision. Strong response to the O-III filter. Good response to the UHC filter. No
response to the H-B filter. At 254X, can see a very faint fuzzy non-stellar blob
with averted vision alone but still needed the UHC filter to identify it as a

18 58.4 -01 04
17.5: appears as a mag 13 stellar object at 82x. A mag 10.5 star lies 1.6'
E which is excellent for blinking comparison and a mag 9.5 star is 5.4' NE.
Using an OIII filter, the pn is comparable to the close following star.
Still stellar at 220x.
Sa3_151 RA 18,58.9 DEC -00,33 MAG ? CSM 14.0 SIZE stellar, on 10/11/96. At 79X, can see directly as a faint star. There is a weak but noticable response to the UHC & O-III filters. It disappears in the H-B filter. At 254X, identified its position exactly in the SEC finderchart. This is a strange one being so bright but having so little response to the filters. This is a first known visual sighting. Kent Wallace, Navaho Flats, California, 20" f 5.0 reflector.

50% of time. Located 2' NE of a mag 10 star.
Abell51 RA 19,01.0 DEC -18,12 MAG 14.0 CSM 15.4 SIZE 64"x58" on 07/21/98. At 134X, faint fair sized ghostly 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 169X, the image is better. At 254X, the image is worse. Identified the field in the SEC finderchart.

On 08/11/96. At 134X, stellar, relatively
bright, requiring the O-III filter and averted vision. Strong response to the
O-III & UHC filters. No response to the H-B filter. At 254X, you can see the
PN with averted vision alone but it required the UHC filter to identify it as
the PN. The PN looked like it had a small disk at 254X. Could not identify the
field in the SEC finderchart. Kent Wallace,

Good response to the O-III & UHC filters. No response to the H-B filter. At 254X, can see the PN as a very faint star with averted vision alone but needed the UHC filter to identify it as a PN.

planetary. Located 6' E of a mag 10 star and several mag 11-12 stars are
near.
Sh2_71 (S.G. 8/21,22/98; Sierra Buttes, 17.5") (Steve Gottlieb)
Sharpless 2-71 (originally catalogued as an HII region) was immediately
picked up 100x using an OIII filter just casually sweeping the area. This
is definitely a "showpiece" obscure planetary in dark skies and I pulled
the rest of the observing group over for a look. 140x provided an excellent
view as this 2' planetary (elongated N-S with a brighter northern end)
appeared mottled with a noticeably irregular surface brightness.

17.5" (8/17/01): Interesting, large PN at 140x using an OIII filter.
The
outline is subtle but irregular. Initially it appeared roughly circular,
but
with concentration a faint extension which sometimes appeared detached is at
the south side, giving a N-S elongation. The rim is brightest along the
east
side and curving around to the north giving a partial crescent impression.
17.5" (8/21/98): immediately picked up at 100x with an OIII filter.
This

140x using an OIII filter. Appears fairly large, elongated N-S and
brightest
along the east side. Seems mottled with a noticeably irregular surface
brightness.

MAG 19.1 SIZE stellar on 08/24/00. At 254X could see a faint star with
averted vision just where the SEC finderchart shows the PN to be but there
is no response to the O-III, UHC or H-B filters. The PN is the westerly
component of what appears to be a pair of faint stars. Perhaps the nebula
is hidden by a central star. This rates a "2?" on the list.

Poor response to the UHC filter. No response to the H-B filter. At 134X & 169X, the image was worse. This is a low power PN. Could not identify the field in the SEC finderchart because it is overexposed. Kent Wallace, Navaho Flats, California, 20" f 5.0 reflector.
I've observed K1_17 with my T445x150(Nag) and [OIII]

This object appeared 70% of time and seem to have a ovoid shape but I
feel that the visual mag is near to be 15.5-16 than the 16.7 is written

This is a fairly small Abell PN, ~40"x30", oriented SSW-NNE. At 100x
using an OIII filter, the object is fairly faint with an irregular surface brightness
but no annularity. Also barely visible unfiltered as an amorphous glow.

Good response to the O-III & UHC filters. No response to the H-B filter. At 254X, could just see the PN as a fuzzy very faint area with averted vision alone, requiring the UHC filter to identify it as a PN. Identified the field in the SEC finderchart.

17.5" (9/5/99): picked up at 100x as a small, irregular glow in a
rich star
field by moving 20' NW of .2483 = 7.9/9.0 at 10". At 220x, the PN is
clearly
elongated ~2:1 SW-NE. The appearance is odd with a much brighter NE end
and
a fainter extension to the SW end. A mag 14.5-15 star is just off the NE
end
in the direction of the elongation. At 380x, a very faint star was
intermittently glimpsed within the NE end. If this is the central star it
is
very eccentrically placed.
