I worked at Celestron-Pacific from about Oct 1965 to about 1971. I originated the sequential serial numbering for the C8, with a simple #1. This continued until I left. I understand the index card box was destroyed ln a flood. Attached are photos of my C-8, #300, which I picked at random from the production line. The optics are quite good; the only caveat is the corrector plate is soft-coated, which I had done by an outside company. They didn't want to heat the corrector, for fear of breakage. The original orange paint was a matte finish Nextel Velvetone, which after 30 years disintegrated, I repainted the scope with Rustoleum SailBlue and Harbor Blue; similar to the earlier Celestrons.
