I regularly use my M10 II on my telescope (homemade prime focus adapter.) I also use a Nikon 135 2.8 AIS with the M10 II mounted on my motorized equatorial mount.

I was able to get 30sec exposures of the Andromeda Galaxy at ISO 800. I really need 60sec. Need to spend more time on drift aligning the mount. I am also trying to identifying slight vibration during the exposures. It might be the standard focuser on the OTA and/or the clock/motor drive.

I designed and built my own barn door style tracker and had huge vibration problem. Identified main culprit as the bal head connecting tripod to the tracker allowing resonation. Cured it by using triangulation, built a simple short adjustable telescopic pole (an extending wash brush handle from hardware store) with a clamp fixed to either end. One end clamps to outermost part of tracker, the other low down on tripod leg. The setup is so much more stable now and vibration has reduced about 90%.

Hope that idea helps you.

Scope is Orion Astroview 6" reflector mounted on Orion equatorial mount with accessory motor drive.

I can post more detail if anyone is interested.
