I was recently looking at an older C8 (1980)and noticed that the
corrector plate (with special coatings) had several small pits in it.
Last question, this user has asked me if he would gain much from
buying
a new optical tube from Celestron to place on his Ultima mount (with
PEC). What is your opinion of the quality of the new Celestron
offerings (C8) compared to the older (1980) C8 product?
Thanks for whatever advice you may have to offer.

Hi:
Those "pits" will have no effect on performance. In fact, they may not
even _be_ "pits". Small specks of grease can look for all the world
like coating imperfections.
As for your buddy, I'm a little confused, as the Ultima (8 or 2000) was
not being made in 1980.
There is no doubt in my mind, however, that current C8s are probably
the best the company has produced.
Peace,
Rod Mollise
