I finally got tired of the microfocuser on my LX200R and got a new Moonlite one with DC Stepper motor. I have to say its one of the nicest (and most attractive if you can say that) pieces of engineering I've seen.
I've connected it to my Mount Hub Pro and it works as smooth as butter. I managed to get my best focus last night with no problems whatsoever and it held it all night.
The only thing I would say is its real heavy and will need to be balanced out but its one of the best aftermarket pieces of kit I've ever bought
A few pics here.
