Quote:keypad, how tracking vs completely manual GEM work is those slow motion knobs on a manual GEM are the worm gears on the mount, on a tracking or goto GEM like the CG-5 rather than having slow mo knobs there are motors attached to the worm gears and that is what drives the mount. because the CG-5 is basically a copy of the vixen great polaris design at heart if one wanted to remove the electroncs and motors and attach slow-mo knobs and make it into a full manual mount one could, in fact older CG-5's did not have goto and some did not even have tracking motors. also another alternative is to tighten the clutches just enough that they will slip if you move the scope but hold if you don't I have done this on mine when using it for terrestrial use but you must be careful when doing so and make sure your balance is good as well. all that being said you never want to manually move a goto GEM via clutches or otherwise if you are using the Goto because it will mess up your alignment.
Quote:Hmmm....You got me thinking now...Does the CG-5 allow you to not use the go-to and use manual tracking via say,... slow motion controls? or is that done with the key-pad??
