Hello:
I took this 10" Celestron out for a spin last night, and it's arguably the best SCT I've used. It was made in 1967, and is an f/13 rather than the newer f/10s. In the picture, you can see that the central baffle tube is quite small and short, allowing for some stray light to get to the eyepiece. The size of the central baffle limits the scope to 1.25" eyepieces, so the field of view is pretty tight. On the other hand, its optics are very good. I could see a nice Airy disk for both components of Xi UMa. Naturally, Saturn was spectacular. I can't wait until I really get her cleaned up.
Cheers
