I put this on my Nexstar 6SE. Fairly easy to install. I got it the first time. Fairly quiet. The real benefit is using it on a Celestron mount which supplies the power and a hand control for focusing manually if you do not want to be tied to a PC. In stock and prompt shipping from OPT!
Now that celestron has modified the design slightly, it actually fits on my 9.25 edge. The original was a couple MM too large and had to be sent back. This is a solid and verges to install focus motor and works fine with Ascom drivers or their own software. Installation was under 5 minutes, msot of which was just reading the instructions. If you own a Celestron SCT, this is a solid and affordable focuser.
Very hard to find information on how to operate it. Now no problems, Thanks
The focus is adjusted smoothly. I like the movement very much. Worth $ 200
The equipment arrived on time and in good condition. When installed, however, at first it didn't work and I even thought it was broken. Already in the calibration step with the manual control he looked literally dead. Visiting astronomy blogs, I found some tips on how to try to correct this problem. The question, however, was far more prosaic. It turned out that the focus course of my telescope was at its end and so the engine couldn't work. I removed the equipment, twirled the focus of my telescope manually, and reinstalled the equipment. From that moment on, everything started to work normally. Calibration was successful and I am already getting super precise focus with my telescope, a Celestron CPC 11 Hedge Deluxe.
