Two G-11 questions

Hey all

1) First light tonight with the G-11 brought out a question re; the Gemini. I use StarTarg and a webcam in the Megrez to set up my alignment. StarTarg asks that you temporarily turn off tracking so that you can see which axis of the reticule west is on. You then re-start the RA motor and continue on until it asks once more that you stp tracking.

How can you do this with a Gemini? Is there a setting you can go to quickly that stops tracking at sidereal rate for a moment without powering down? To power down means you have to go through the warm-start procedure all over again.

2) Does anyone use the Losmandy polar scope in Australia? I'm not sure that it would work here given that its FOV is around 12 degrees, and the engraved images of Achenar (a-Eri) and Crux are in reality nearly 60 degrees apart! How do you see even one of these markers through the polar scope and still see the pole? I take it that you can't use it here....
