Re: Jerky RA drive motion

No - this was noticed before proceeding to connect the SkyFi device. This was observed during the GoTo bright star.

Re: Firecapture autoguide with Gemini 1 ?

Re: Adding grease to existing greased worm and wheel
I heard about Nye Fluorocarbon Gel 868H, but it seems very costly. CRC grease looks like a very good option - cheap and no mixing.
