Hi Robert.
Mine is on a 10" GSO Newt, and I love it. I didn't buy the motorised one, I bought the normal CR2 with 8:1 fine focus knob. I motorised it DIY style, with thanks to RAJAH235 making a motor for me.
You can see it
here in this thread.
You can also see more of my moonlite
here on the DIY page.
Hope that answers your questions.
