I just won 2 Celestron telescopes at a local auction. One is marked C8 but the other one has no identification plate on it and is the reason for my posting. It measures approx. 29" long and has a 15.5" diameter. The port for the eyepiece measures approx. 2" across. I am wondering if this is a c14 or perhaps some other model?

I also need to get and eyepiece for this. Can anybody recommend what would be a good one to start out with. I can't wait to try this out. Thanks in advance Dave
