Re: Specs for the main axis thrust bearings.
The mount does not seem to stop. The guiding will correct itself in 2-3 pulses after the 30 second phase and the mount continues to make drive noises. As far as did the mount receive a guide pulse, I

Re: Specs for the main axis thrust bearings.
Why, do you need replacement thrust bearings?? Why not just call Losmandy and order them, they have the correct factory spec parts in stock sitting on the shelf.? There is a bit more to it than just

Re: Gemini-1 Failure
Michael has repaired my Gemini-1 and it's on its way back to me. Problem was moisture got inside and accumulated in the lower end of the enclosure. This corroded the fuse holder and a capacitor.
