Some time back, I came across one of the older orange Celestron C8s. I'm guessing it was made in the early 1980s. I have spent the last few years replacing a few parts, and finding a few others, and am close to having it ready to use. The OTA seems to be in good condition, and the mirrors have the Starbright coatings. Just to be sure everything was OK, I sent it to Celestron. Their initial evaluation was all the C8 needs is cleaned and laser collimation.
I plan on keeping the C8 long term, even if I procure another telescope a few years down the road. So the question is, while it is at Celestron, should I consider having the original mirrors recoated? If it were your telescope and you were planning on keeping it for a long time, is there anything else you would want Celestron to check out or replace while they have it?
