Items offered by John A.

1. Criterion RV-6 Dynascope. I am the Original owner; around 1970. Black tube (original white tube was busted in a move.) Clock drive. Equatorial mount, RA slip-clutch needs work. Hasn't been used in 30 years. An historic 6" Newtonian telescope on a pedestal mount that needs a little love. Asking $150, less for an educational use. No eyepieces but I'm still looking around the basement, maybe I can find some.

2. Meade ETX-125, about 20 years old, I can't make it align anymore (it just buzzes around in circles). Optics 100% great, but needs someone smarter than me to make it auto align. Includes field tripod. Includes AC adapter, a hard case for the telescope and soft case for the tripod, solar objective filter. Asking $250, less for an educational use. No eyepieces. 

3.  Decorative Tasco 60mm equatorial refractor on a wooden tripod in a wooden box. I am the original owner circa 1968.  A few 0.96 eyepieces if I can find them. This is a beautiful telescope, but It is worthless for astronomy. It is a fantastic home or office decoration. $50 or OBO.
