I have an older GEG from a 14" Celestron. This has been sitting around for the past 10 years and hasn't had any use. I just happened to find it while digging through some old stuff in the garage. I have cleaned up the optics as best as I could do. I haven't noticed any scratches or problems with the lenses or the prism in the GEG. Everything looks like it is in good condition. It comes with the main lens adapter, the off axis guider tube (no eyepiece), the 2" adapter and the 1.25" adapter. Take a look and see what you think. Make me an offer.
