I have a nikon DSLR (D100) does anyone know where
I could get a 1.25 or 2" adapter?

No, because there is no such thing.

What you *can* get, however, is an adapter from the
telescope focuser to a t thread, then a t thread
adapter to fit your camera. Both are standard items,
well documented in all the usual references.
