This drive uses a stepper motor that clicks a few times per second to move at the sidereal rate. I could hear its clicking amplified in my 4.5" reflector's OTA. I tried imaging Saturn at 150X magnification and in my captured AVI you can see it darting back and forth. This drive may be useful for wide-angle piggyback astrophotography, but it's not worthwhile for through-the-scope imaging.
