Goto system is about 2 Years old. Works great. Comes with Tray, Tripod, NexStar Computer (latest Firmware upgrade from Celestron, tested and works great with The Sky) and 80mm cradle. Has solar tracking feature that I used to track the sun using the telescope and my Coronado 40mm SolarMax #39(a perfect match, might I add). SolarMax and Telescope not included. I might part with the whole package for the right offer but I'm mainly interested in selling the mount ONLY.
