Location Elk Grove, CA
Notes Seeing and transparency average.  Flexure is causing elongated stars.  The OIII channel VERY weak.  Needed more time, but the location of my house reduced the night's data to only around 2 hours total.  Couldn't get enough data (actually got lazy and tired of working on this one! ) so the image is noisy.
