Great scope. I use mine mainly for imaging but it works fine as a guidescope for my C11. Many of my shots are taken with a M72 from surburban skies using a skywatcher field flattener, CLS filter and a Canon 450D.

Its a good grap and go scope too with great contrast. Put it on an altaz mount with say a 27mm panoptic and you will see what I mean.
