If you would prefer your Questar's R.A. knob to be on the near end of the base rather than the far end (or vice-versa), you can easily do it yourself. Here is the procedure that has been posted elsewhere but bears repeating:

1. Remove the eyepiece.
2. Make sure the focus knob isn't backed out too far.
3. Move the diopter adjuster (i.e. the finder focus ring) counterclockwise so that it clears certain protuberances on the base of the main tube when you perform Step 4.
4. Rotate the main tube about its long axis so the eyepiece tube points down when the main tube is horizontal.
5. Swing the main tube (in elevation, that is) so that the control box passes down between the fork arms and emerges on the other side.

Voila; the RA knob has switched ends.
