GM8 RA clearance issues with Gemini2!!! Hello!
Posted 23 December 2012 - 01:51 PM
Not having access to the zenith and a good part of the meridian from the east side of the mount is a major problem if you are doing tempral timelapse videos of the sun or planets. Just as important is the potential of destroying the drive motor while manually moving the scope.
This is most disappointing and I will likely be returning the Gemini 2 and go back to my stepping motors. No other mount in the same class has this issue. Losmandy what were you thinking?
Thanks for any input.

you will need a shorter dovetail
I can move the tube rings down the dovetail for a bit more clearance, but that doesn't help with my solar refractor or C9.

The MI250 has a similar problem. One fix was the addition of a declination spacer that allows you to adjust for the RA motor...
Maybe you could find a machinist in your area to produce something similar?
Yeah, after looking at the mount, turning a short extension is pretty straight forward and should get me access to the meridian from the east side of the mount. Good call.

Good luck! And post pictures for everyone when you're done

A 1/2 inch spacer would be a great idea and I wish I had access to a lathe.
