Image backwards left-to-right
I got the impression that the Celestron 50AZ, 60AZ, and 70AZ, all had correctly oriented images. The 50AZ is corrected up-down, but is backwards left-to-right. To get a correctly oriented image you need to move up to the 60AZ or 70AZ.I also noticed that when the center of the image was in focus the outer ring was distorted or out of focus, so I really could only look at about half the image area.I have returned this and got a 70AZ instead, and am quite happy with it.
