G-11 Tracking ProblemPosted By Joe Baldwin |
Alex,
I encountered a similar problem with my CI-700. The spur gears are fixed on the motor shaft with allen-head set screws. As these screws are tightened, they tend to push the shaft away from the centerline of the gear causing runout. In my case, the gears would just bind up and stop moving for a beat or two causing a dropout in the guiding motion. I was able to respace the gear mesh so it wouldn't bind up when the high spots of the gears met up. The gear system in the G11 is a little different but this gives you something to look at. Also, you might try posting this on the Yahoo Scopemounts group:

Very helpful bunch

Very nice Ed. Are you using the NoRaw modification for these images? They look very clean.

Fantastic image. Nice and deep. BTW, it's luminance not luminescence.

Taking apart a CI-700Posted By Joe Baldwin |
Shay,
Welcome to the world of Celestronomy. The CI-700 is a good mount if you get past some of it's quirks. It sounds like you are having some issues with the worm gear spacing and maybe the setting of the pressure plate screws. When the spacings are wrong it will bind up. Send me a private message with an email address and I will send you all the material I have on the CI-700. I would suggest doing the simplest things first to see if that solves your problems. Tearing down a CI-700 requires a lot of care and some specialized tools.
Cheers
Joe

Maybe use a Hartmann mask and focus through the viewfinder. You need a bright star and a flexible neck but it works.

Celestron CI-700Posted By Joe Baldwin |
John,
A lot of people have been upgrading their CI-700's to the Gemini system and I have seen several ads for the old controller and motors. Maybe post a wanted ad under Mounts,drives and Tripods and see if you get any nibbles.
