Back to Observing Reports July 23, 2011 at IHOP NELM = 6.5 Seeing 3 out of 5 Transparency 3 out of 5 - started off with moderate humidity, but dried off within 30 minutes of astronomical twilight. Tonight, I've decided to observe several pre-selected obscure planetary nebula and to finish off the last flat galaxy in my Serpens list. And here is the brief version of my observing report. Equipment used: 22” f/4 reflector 24mm Televue Panoptic 12.5, 9 and 7mm Baader Genuine Orthoscopics 16mm Zeiss 0.965" orthoscopic 10 and 6mm Zeiss ZAO-II orthoscopics Lumicon O-III filter Orion Ultrablock filter Astronomik CLS filter

UGC 9760 15 12 02.6 +01 41 56 14.7p 2.4x0.2’ 22” (255, 328 and 383x) – Very faint, thin, even surface brightness glow with somewhat defined edges and diffuse ends. A 13.8 mag star is on the NE tip. PA = 60 and 0.8’ long. A blazing mag 11.1 and 12.9 double star lies just 2.2’ NW hindering the view a bit. |
Shane 1 16 21 04.5 -00 16 12 12.8p 14.7* 6” 22” (255 and 383x) – Bright, very small
round disk with well-defined edges at 383x. O-III filter
really brings it out well. 0.1’ across. A mag 12.3 star
lies 1.8’ west and a faint mag 16.5 and 16.9 double star
lies just 0.6’ SW. This object was discussed by Sue French
in the June 2010 issue of Sky and Telescope. Thanks
Sue! |

PNG 010+07.4 (Kohoutek 1-4) 17 40 26.8 -27 01 03 ? 20.3* 37” 22” (184, 255, 328 and 383x) – Very
faint uniform brightness round glow with diffuse edges. A 12.2 magnitude
star is on the NE edge.
About 0.5’ across.
Good response to Ultrablock, mild response to
O-III. Best
seen at 255x.

PNG 027.6+16.9 17 41 41 +03 07 02 16.3p 14.9* 94” 22” (144, 184 and 255x) – field was
located, but no nebula.
Both O-III and Ultrablock were used. I will try this object again as Eric
Honeycutt successfully observed it. But Kent Wallace
didn't see it. |

PNG 027.0+01.5 18 35 11.6 -04 29 06 ? ? 39” 22” (184, 255 and 328x) – Considerably faint round glow with defined edge with a very bright central star. Estimated magnitude of the central star is about 11.5. Not visible without filter. Ultrablock brings it out pretty well and a similar response with O-III filter. About 0.5’ across. |

22” (184, 255 and 328x) – Considerably bright round glow with diffuse edges. A 11.5 magnitude star is just off the west edge. Mild response with Ultrablock and good response with O-III filter. About 0.6’ across. |

Sweet Pea 18 41 41.9 +65 11 58 22” (383x) – Extremely faint, only
visible with the Astronomik CLS filter. Only pops in and
out. Stellar. Both the
Ultrablock and O-III makes it invisible. This object
was discovered by my good friend, Jimi Lowrey. He
was perusing the Sloan Digital Sky Survey lookign for ring
galaxies, then ran across this green "star".
Generally there are no green stars on the Sloan, we
decided to look at it with the 48". It was
definately fainter than the nearby stars. The
Astronomik CLS filter helps this object the most. Here is a short
blurb on it. In a nutshell, this object has
some lines consistant to a planetary nebula, but it's
location is really bizzare...it is in Draco far above the
plane of the Milky Way and is estimated to be about 25,000
light years away...which puts this object well outside of
the plan of our galaxy. It was theorized that this
object was flung off our galaxy or from the "galaxy" that
passed by the Milky Way many years ago. |
