This is a Starguide SG4 mount (= Nexstar 4 equivalent) WITHOUT the OTA. I planned to attach a 5" Mak or a 4.5" short Newton (like Orion's Starblaster) to it for a vacation goto scope using the Baader(R) bracket.
An alternative project could be a robotic remotedly controlled mount. I can email you the instructions.
Comes with both the HC hand controller and the GoTo controller.
I have too many projects going on..
Yours for $150 shipped.
Look also on the recommended Nexstar tripod, my ad 174162.
