Well made focuser
This Focuser is well made . No play , no slippage, no problems whatsoever. Smooth movement even at zenith carrying a rotator, filter wheel, and a cooled camera. No comparison to the cheap imported units available. A very stable piece of equipment. Highly recommend this model.

Good for autofocus
I fitted the Focuser to my Skymax 127 easily. Just clears the focus knob after take the rubber off. I fitted another thinner knob over it so I can manipulate both to get fine focus. I have not fitted an autofocus on yet but I feel it will meet it’s purpose.
