The Orion AccuFocus for Dual-Speed Crayford Focusers is a great way to focus your telescope. Instead of focusing by hand, which can cause vibration, you use the pushbutton hand controller for smooth, precise focusing without vibration.

Didn't work with my focuser and camera.

I bought this for my Orion 190mm mak-newt, which came with the dual focuser. When I set the tension on the focuser high enough to support my camera (a little over two pounds) the motor has insufficient torque to turn the focuser. This could be a problem with the dual speed crayford focuser or the motor, but either way, I cannot really use this, so I'm returning it.
Also note - yes I'm using the tension screw, not the locking thumbscrew, to set tension as per installation directions and telescope directions.
I'm giving it two stars, because it seemed like it would work until I actually attached the camera, tightened the tension enough to keep it from moving the drawtube with its weight and then tried to operate the focuser.
Other notes - the attachment screws seemed awfully short as another reviewer noted. Also the motor would have extended beyond the front of the telescope, which would have made me a little nervous when moving it around, but that is more of a whole solution problem than a motor problem.
Cons: doesn't work with heavier camera.
No, I do not recommend this product.
