Celestron Fastar 8 at prime focus f/1.95, PixCel 237. This is my original thirty image integration of 10 seconds each, unguided at -5 degrees Celsius. Post processed with CCDOPS v3.78, log scaled and sharpened. The difference in orientation and image size is due to the placement of the camera and cropping induced by poor tracking of this image.
