In the summer of 2006 I had a nearly perfect 9.25 inch Celestron SCT on a Meade LXD75 mount. I was a star test collimation freak at the time and decided to install something called Bob's knobs to make collimation to the nth degree possible using star testing. Unfortunately, I must have been all thumbs that day and although exactly what I did eludes me after all these years, the corrector plate somehow became detached/loose and moved but didn't damage anything else in the optical train. I was unaware that the corrector plate had alignment numbers on the edge so when I put it back in place the scope didn't behave very well. I couldn't understand what the problem was for three years during which time I had fuzzy images of the moon etc., then I realized that I'd put the 3 o'clock number where the 1 o'clock number should be. I rectified that in 2009 and made a note at the time that the scope behaved much better. I still had the impression that the scope wasn't quite as precise as it had been before my debacle though. I switched more and more to using my Mewlon which is a shame as I considered both scopes to be essential equal optically even if the Mewlon 250 was a lot more expensive.
Now I want to use the 9.25 inch again. It produces very sharp images at low power. I'm not as sure how great it is on detail at very high power though compared to the old days. I've just got its old LXD75 mount working again.... found the hand paddle controller and bought a new power supply. It seems to work although the AutoStar Suite by Meade that goes with the mount isn't fit for modern computers. But if I remember right, the had paddle had a lot of inherent capability on its own. Any thoughts?
