I have a JMI Motofocus that fits most refractor telescopes and some newtonian reflectors, Orion, Sky instruments, antares, etc. It is model MFCREF. You can check the jimsmobile web site to confirm compatibility with your scope. This is the motofocus unit and hand controller. New they sell for $129.95 plus $6.00 shipping. I am asking $60.00 plus $6.00 shipping in the continental U.S.
