Notes Seeing and transparency average to poor. Using the Celestron F/6.3 reducer with the C80ED showed some alignment/coma issues.  The camera appears to be tilted in the x-axis as witnessed by the star shapes on the right side of the image.  I massaged the results in PS, to alleviate this result, but it is still noticable..
