Newbie question.

Hi. I have a classic orange-tube C8, which obviously takes standard
1.25" eyepieces. Is there any way of using 2" eyepieces in it?
Thanks in advance.

Hi:

Yes. You'll need an inexpensive item, a "2-inch adaptor," aka "2-inch
visual back." You'll also need a 2-inch diagonal and eyepieces, of
course. ;-)

We got rid of our old -- probably late 1970s -- C8 about 12 years ago,
but if memory serves, it had the same mounting on the back as the
modern ones do, and I *think* we had an adaptor that would work with
our few 2" eyepieces: just a tube that threaded onto the visual back,
not a full 2" star diagonal. Check with any Celestron dealer online.
You can get either a 2" diagonal, or one of those adaptor tubes (if
you can manage to observe without the diagonal, which means not
looking up very high!)
