Abell58 RA 19,18.3 DEC
+01,47 MAG 17.4p CSM ? SIZE 44"x37" on 09/12/98. Tried to find this PN
but had no luck. Couldn't identify the field in the SEC finderchart. Kent
Wallace, Navaho Flats, California, 20" f 5.0 reflector.
Nassau2 = Na2 = PK 26-11.1
19 18.3 -11 06
17.5: visible at 105x as a mag 13.5 stellar planetary. Good contrast gain
with OIII filter. Located in a close trio with two other stars close N
less than 30". These form good comparison stars for blinking.
NGC6778 = PK 34-6.1
19 18 24.8 -01 35 47
V = 12.3; Size 25"x19"
17.5" (9/5/99): fairly bright, but small disc picked up at 100x.
Easily
takes high power. Nice view unfiltered at 280x - the PN has an irregular
surface brightness with a brighter center but no central star and appears
slightly elongated WNW-ESE, perhaps 20"-25" in diameter. At 500x
the outer
edge of the rim fades and is not sharply defined. At moments a sparkle was
visible at the center with this power. Located 5.0' WSW of mag 9 SAO
143251.
13": bright, fairly small, estimate V = 12.0-12.5. Very nice view at
214x
with a UHC filter and slightly elongated WNW-ESE with a fainter rounder halo
suspected.
Ngc6778 = 18H18.4 -01°35' To the 8 inch , recognized to 48x by blinking. TO
123x+OIII, it is a small stains oval degraded. It very net and well contrasted. (230/08/98

V = 11.4; Size 111"x109"
17.5" (7/12/99): at 100x appears fairly bright, round, ~1.6' diameter with
a
darker center. I used a variety of magnifications and filters but the most
interesting view was at 220x using a UHC filter. With this combination the
PN is slightly elongated E-W and clearly brighter along the southern rim with
the brightening tapering towards the ends so this brighter portion had a
crescent appearance. Because of this asymmetric rim the darker center
seems
offset and only weakly brightens at the NW rim. A mag 13 star is just off
the NE edge 1' from center.
17.5": at 222x and UHC filter; very large, about 1.8' diameter, much
brighter
on the SW portion of the rim, darker center. A mag 13 star is just off the
NE edge.
13": brighter rim mainly on the SW side, slightly annular appearance.
A
faint star is off the E edge.
NGC 6781 = PK 41-2.1
19 18 28.2 +06 32 23
V = 11.4; Size 111"x109"
(6/30/00): at 220x unfiltered this fairly bright PN has a 1.5' round halo.
The rim is brightest and more well-defined along an arc on the S and SE rim.
The central 45" hole is slightly darker and irregular in surface
brightness.
A mag 13 star is at the NE edge and once or twice I caught a fainter glimmer
of an interior star north of center.
Ngc6781 = 19H18.4 +06°32' Eagle
To the 8 inch, recognized to 48x. TO 123x, it is round, large to them indefinite limit.
One notes it brilliant enough and uniform flash. The filter OIII does not bring anything
more. (20/08/98 T=2 S=4)

Abell60 = PK 25-11.1
19 19.3 -12 16
17.5: at 83x and OIII filter appears as an extremely faint, moderately
large round glow. Visible only part of the time with averted vision as the
surface brightness is extremely low. Estimate V = 15.3-15.7 although
viewed well past the meridian.
Abell60 RA 19,19.3 DEC -12,15 MAG 16.2 CSM 18.5p SIZE 88"x77" on 09/12/98. At 79X & 134X, faint, good sized unsteady disk, requiring the O-III filter and averted vision. Fair response to the O-III filter. Poor response to the UHC filter. No response to the H-B filter. At 169X, the image is worse. Identified the field in the SEC finderchart but the finderchart was no help in finding the PN because it is overexposed. Kent Wallace, Navaho Flats, California, 20" f 5.0 reflector.
M4_14 = PK 43-3.1
19 21.0 +07 37
17.5: not seen initially without a filter at 225x. Easily visible, though,
using an OIII filter as a small faint disc of uniform surface brightness
situated less than 1' SE of a pair of stars with separation about 25".
Once exact position known the planetary can be glimpsed without a filter.
Estimate 10" diameter and mag V = 15.0-15.5.
M4_14 RA 19,21.0 DEC +07,37 MAG 14.9 CSM ? SIZE 8" on 10/30/97. At 134X & 169X, stellar, requiring the O-III filter and averted vision. Good response to the 0-III & UHC filters. No response to the H-B filter. At 254X, can see a very faint, just non-stellar blob with averted vision alone but needed the UHC filter to identify it as a PN. Identified the field in the SEC finderchart. Kent Wallace, Navaho Flats, California, 20" f 5.0 reflector.
Wray16_423 RA 19,22.2 DEC -31,31 MAG 13.4 CSM ? SIZE stellar, on 08/28/9 7. At 79X, can see as a star with averted vision alone but needed the O-III filter to identify it as a PN. Strong response to the O-III & UHC filters. No response to the H-B filter. Identified the field in the SEC finderchart. At 134X, 169X & 254X, was still stellar but easier to see than that at 79X.

He2_432 = PK 55+2.1
19 23.5 +21 08
17.5: not visible initially without a filter using ESO-Strausberg finder
chart. Using an OIII filter, good contrast response and appears as a very
faint stellar object which is almost visible steadily. Located 3' SSW of a
mag 9.5 star. Once seen with the filter, can glimpse at moments without
filter although extremely difficult. Forms a pair with planetary He 1-1
5.4' ESE. Estimate V = 15.5-16.0.
He2_432 RA 19,23.4 DEC +21.08 MAG 16.9 CSM ? SIZE 5" on 09/11/98. At 134X & 169X, stellar, requiring the O-III filter and averted vision. Good response to the O-III & UHC filters. No response to the H-B filter. Can see He 1-1 in the same field. At 254X, can see the PN with averted vision alone as a very faint fuzzy patch requiring the UHC filter to identify it as a PN.

19 24.4 +09 54
17.5: fairly bright stellar pn, estimate V = 13.0. Verified with OIII
blinking at 105x. A mag 12 star is 1.4' W but with the OIII filter the
planetary appears 0.2-0.4 magnitude brighter than this star. Also, a mag
13 star lies 1.1' S forming an equilateral triangle with Vy 2-2 and mag 12
star. Appears stellar up to 286x.

He1_2 = PK 55+2.3
19 26.7 +21 09
17.5: at the exact ESO-Strausberg position a mag 16 "star" is occasionally
visible at 225x. Sighting uncertain, though, because this object dims to
invisibility with an OIII filter at 225x and 140x. Located just 2.5' W of
a pretty evenly matched double star …2523 = 8.4/8.5 at 6".
He1_2 RA 19,26.6 DEC +21,10 MAG ? CSM 16.7 SIZE
5" on 09/30/97 & 09/12/99. Tried to find this PN but had no luck. Identified the field in the SEC finderchart. Could
see the star shown in the SEC finderchart as the PN but could get no
response to any filter. Perhaps the central star hides the nebula.

V = 11.4; Size 6"
17.5" (9/5/99): picked up by blinking with an OIII filter at 100x as a mag
11.5 "star". At 220x, appears just non-stellar and is situated
~2' S of a
mag 10.5-11 "comparison" star which is a half magnitude brighter than
the PN
(unfiltered). Good response to blinking with a UHC filter. At 280x
and
380x, the PN is very small but clearly nonstellar, <5" diameter with the
blue-greyish color. Easily takes 500x but no other details visible except
two mag 15 stars which are close W and NW forming a tiny equilateral triangle
with the PN.
13": fairly bright stellar planetary at 88x, good OIII blinker in a rich
star
field, estimate V = 11.5. Just non-stellar at 350x and about 3"
diameter. A
mag 11 star is 1.8' N.
8": appears slightly non-stellar at 385x. A similar field star is
just 2' NW.

V = 12.0; Size 62"x49"
17.5" (7/11/99): at lower powers appears moderately bright, irregularly
round, ~1' diameter with several stars involved or nearby. At 280x, the
view
is very unusual with three stars involved and others nearby. The brightest
is a mag 12.5-13 star at the NE edge. The mag 13.5-14 central star is
visible with direct vision. Finally, a mag 14.5-15 star is at or just off
the W side. The planetary is slightly elongated 4:3 SW-NE with an
irregular
surface brightness. The rim appears brighter near along the E and NE side
and weakest at the W edge. Nearby stars include a mag 13 star ~1.5' NE
(nearly on a line with the central star and the star on the NE edge) and a
mag 15-15.5 star close SSW of the star at the W edge.
13": moderately bright, elongated WSW-ENE. Unusual appearance as four
faint stars are very near or involved including the faint mag 14 central star
visible with averted vision. A mag 13 star is at the NE edge 27" from
the
center, a very faint mag 15 star is at W edge and a similar star is just NW.
The rim is possibly slightly brighter on the E edge.

19 34.8 +30 31
17.5 (7/20/96): at 88x Campbell's Star appears as a mag 10.5 stellar object
with a slight pinkish tinge when compared to similar field stars. This
coloration is not evident at moderate or high power. Using 220x, the 10"
halo is clearly visible surrounding a very bright center and well seen at
410x. The response to Hß filtration is quite striking at all powers.
17.5 (7/1/89): at 220x this interesting planetary is clearly non-stellar
although very small, estimate 10" diameter. A bright mag 12.5 central star
(BD +30 3639) is embedded within a small halo. Unusually bright, estimate V
= 10.5-11.0. Very unusual filtration response as dims with OIII filter but
has a good contrast response to Hß filter!
