Mag 12.1  Size= 5"
On 02/19/99.  At 62.5X can see the PN with averted vision alone as a faint star forming a pair with another faint star but needed the O-III filter to identify it as a PN.  The PN and the faint star appear to be of similar brightness, but through the O-III filter the PN becomes much brighter than its mate.  Strong response to the O-III filter. Good response to the UHC filter.  No response to the H-B filter. At 100X and 200X the PN is still stellar. At 200X a very faint star is quite near the PN.  This is a first known visual sighting.

M2_5, RA 17,02.3 DEC -33,10 MAG 16.4 CSM 16.2 SIZE 5" on 06/25/97. At 169X, it forms a triangle with two faint stars. The PN can be seen with averted vision alone but requires the UHC filter to identify it as a PN. Poor response to the O-III filter. Fair response to the UHC & H-B filters. It is rare to get a H-B response so this must be an unusual PN. Identified the field in the SEC finderchart.  Kent Wallace, Navaho Flats, California, 20" f 5.0 reflector.

RA 17,04.6 DEC –33,59 MAG 14.4 SIZE 6”CON Sco SKY 22 URA 376 MILL 1440
This PN was discovered by Guillermo Haro in 1952.
Field Description: At 62.5X, can see as a faint star with averted vision alone, requiring the UHC filter to identify it as a PN.  Fair response to the O-III filter.  Good response to the UHC filter.  Poor response to the H-B filter. At 100X, can see the PN directly as a faint star but it still requires the UHC filter to identify it as a PN.  At 200X, the PN is still stellar.

No response to the H-B filter. Identified the field in the SEC finderchart. At first it looked like a faint star with averted vision alone but the SEC shows the PN next to a faint star so I was seeing the faint star. This is a first known visual sighting.

13: at 166x, fairly bright, small, about 15" diameter, estimate V = 12.0.
At 214x the mag 13 central star is visible in good moments, otherwise the
planetary has a brighter center.  The disc can be resolved at 79x.  Located

17 05 37.9 -10 08 34
V = 14.6;  Size 39"x15"

17.5" (7/9/99): picked up a low power but best viewed at 380x.  The faint
central star is cleanly resolved with two thin "jets" extending N-S, roughly
15" on either side of the star.  The nebulosity dims slightly near the
central star but is not detached.  This unusual bi-polar object looks more
similar to a fairly faint edge-on galaxy than a PN although the tips of the
extensions do not noticeably taper.  No response to filtration.

13": at 166x appears as a moderately bright, very elongated planetary but
does not respond positively to OIII or Daystar 300 filters!  The central star
is visible at 214x. A small group of stars including a mag 12 star lies 5' S.
Classified as a bipolar PN or possible proto-PN.

M2_9 (Butterfly Nebula), RA 17,05.6 DEC -10,09 MAG 14.6 CSM 15.5 SIZE 39"x15" on 06/28/95 & 09/09/99. At 134X & 169X, can see the PN as a fuzzy faint near double star requiring the O-III filter and averted vision to identify it as a PN. Good response to the O-III & UHC filters. No response to the H-B filter. At 254X, through the O-III filter, the PN appears to be two bright spots, quite close, with a linear smear across the spots. There is no SEC findercharts for this PN, only four different frequency shots of this PN. Kent Wallace, Navaho Flats, California, 20" f 5.0 reflector.

17.5: using 140x and OIII filter a very small disc about 5" diameter was
glimpsed repeatedly at the correct position.  Without filter there are a
couple of fainter stars very near this position although the Strausberg-ESO
finder chart reveals these are field stars and the sighting was valid.
Located 7.5' NE mag 8.4 SAO 185008.

Th3_1, RA 17,05.8 DEC -25,24 MAG 14.9 CSM 17.8 SIZE 6" on 07/19/95. At 106X, required the O-III filter and averted vision. Near a 8th MAG star. Fair response to the O-III & UHC filters. No response to the H-B filter. At 169X, faint, hint of a disk, faint stars nearby.  Kent Wallace, Navaho Flats, California, 20" f 5.0 reflector.

At 280x (unfiltered) the Bug Nebula is a remarkable, high surface brightness
object, elongated 3:1 WSW-ENE, ~2.0x0.7'. The intensely bright 10" core
appears elongated SW-NE and is offset to the east of center. A quasi-stellar
nucleus sharpens to a stellar point when the seeing steadies. The western
wing is longer and is nearly split at the midpoint by a dark slash oriented
N-S with a brighter condensation at the west end. The shorter eastern wing is
more pinched and just past its midpoint there is a kink and it angles towards
the SE.

At 280x using a UHC filter this bright but compact PN was elongated 2:1 in
the direction of a mag 12 at the NNW edge, ~25"x12". There is a large, bright
lobe or condensation at the north end with a smaller, fainter knot at the SSE
end. At moments the lobes appear completely "resolved" with a darker gap in
the center. The view at 500x was excellent! The fainter southern lobe appears
elongated and slightly offset from the major axis of the PN. The lobes are
bisected by a darker lane oriented SW-NE and oblique to the minor axis. The
brighter knot at the north end has a mottled appearance and irregular shape.

RA 17,20.8 DEC –51,45 MAG 11.1 SIZE 16”x11” CON Ara SKY 22 URA 433 MILL 1417
This PN was discovered by John Herschel on June 19, 1835.
Also known as J.H. 3675 & GC 4248.
Field Description: At 62.5X, can see as a faint star when using averted vision alone, requiring the O-III filter to identify it as a PN.  Good response to the O-III & UHC filters.  No response to the H-B filter.  At 100X, a faint small disk is visible.  At 200X, the disk can be seen but no central star is visible.
Observed at Mt. Pinos on 07/12/91 & 06/26/92 and at the pullout on the road to Mt. Abel on 05/19/93 by Kent Wallace using an 8” f/10 SCT.

M3_38, RA 17,21.1 DEC -29,03 MAG 16.6 CSM ? SIZE stellar, on 06/27/97. At 134X & 169X, could see both M 3-38 and M 2-11 in the same field. M 2-11 was quite a bit brighter than M 3-38. M 3-38 required the O-III filter and averted vision to find. Good response to the O-III and UHC filters. No response to the H-B filter. M 3-38 appears stellar. At 254X, could see the PN as a faint star with averted vision alone but required the UHC filter to identify it as a PN. Identified the field in the SEC finderchart.

M3_39 = PK 358+5.1    VIEW IMAGE
17 21.2 -27 12
17.5: best at 105x using an OIII filter; with this combination appears very
faint, very small, estimate 15" and mag V = 15.0-15.5.  Can just hold
steadily with averted vision once position known.  More difficult at 220x
using a Daystar 300 filter.

M3_39, RA 17,21.2 DEC -27,11 MAG 15.3 CSM ? SIZE 21"x15" on 06/27/97. At 134X, small fuzzy disk requiring the O-III filter and averted vision. Good response to the O-III filter. Fair response to the UHC filter. No response to the H-B filter. The PN is right in the Pipe Dark Nebula. At 169X, can see a faint hint of the PN with averted vision alone. At 254X, could definitely see the PN with averted vision alone as a small faint fuzzy blob. Identified the field in the SEC finderchart. Kent Wallace, Navaho Flats, California, 20" f 5.0 reflector.
