The second Ultima 100ED Celestron just returned after my complaint about coma in the center of the field. It went from being pretty bad to absolutely unusable at any power.
Recently I paid Celestron to collimate several C90s; they came back worse than when I shipped them--twice!
Over the years I have had good results with Celestron warranty work and customer service. But in my experience they now appear to be out of control.

"--Granted, that's a worse case scenario. The destruction might in fact be ... limited to our own galaxy."
