|           | 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

 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. |

 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! | |

 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.

 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. | |

 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. | |

 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. | |
