I will be following your progress with great interest, Steve, as the ever-changing position of the eyepiece is the main drawback to GEM mounts. I have an 8" Newt on HEQ5 and have given up trying to rotate the tube "on the run" as 9 times out of 10 I disturb the mount axes and have to re-do the star alignment. Moving between standing on the floor, standing on a footstool or sitting on an adjustable-height stool, even on a tour of a small sector of the sky, is tedious and time-consuming.
