Celestron Fastar 8 at prime focus f/1.95, PixCel 237. Six image integration of 20 seconds each, at -14.49 degrees Celsius. Post processed with CCDOPS v4.00, log scaled and sharpened. Not nearly enough SN, and the processing added some artifacts. Overall a pretty awful shot. I was not having a good night, and the seeing was terrible. Stellar diameters were twice as big as several nights before, even after spending quite a while on focus. The field of view measures approximately 30 by 40 arc minutes. The Omega (Swan or Horseshoe) Nebula is one of the most conspicuous galactic nebula in the northern sky.
