$50 · Celestron lenses x2 and camera mount

I had an 8 inch Celestron reflector a few years ago, and sold it. I found these lenses and this camera mount while cleaning up. The lenses are unused, the camera mount was probably used once or twice. I have no idea what they're worth, but the original prices are still on the lenses ($59.95 + $44.95), and the camera mount must have been $30. That's about $135. $50 takes everything. Let me be clear that I know very little about telescopes and lenses, in spite of having had one (I have a refractor now). So if you have questions about focal length, exit diameter, curvature, etc, let me save you some time: I don't know.
