more moon

One night later -- same camera, same eyepiece -- but my old Celestron 8" scope. You will see that the pictures are generally of the same portions of the moon except at somewhat higher magnifications. That is because the Questar is about 1500mm focal length -- the Celestron, 2000mm. All of the pictures are full-frame, except the first one which was slightly cropped.
Looking at the prints of these same pictures, the Questar's are as good, if not better than the C's. Of course the air may have been steadier & clearer, but I'm impressed nevertheless when a 3 1/2" scope can match an 8" one.
