Last Christmas I received a Questar 3.5 Standard model. I have been working at high resolution webcam imaging (for a 3.5") using techniques I have learned on my C14 over the years. Just last month (June, '08) I made some headway on this last month when I got the pipe pier in the ground in my back yard and the results can be seen at: http://www.lpl.arizona.edu/~rhill/questar.html
In mid-June our "monsoon" began and it has been cloudy almost ever since or I'd have more posted. However, using the 2x barlow with a webcam the finger controls were too coarse. So taking a thought in Robert Reeves' book "Introduction to Webcam Imaging" I used a clothespin on the focuser but what to do about the RA and Dec.? After some prowling around I found that stainless hemostats work really well with a little bending and some duct tape to avoid scratching and abrading.
You can see the Questar at work and a close up of my jury-rig slow motions at the bottom of the above page.
