Hi everyone,

I have a 6 month old Megrez 90. The type which does not have the tripod bracket. It's focuser is the dual speed rack & pinion style.

I would like to attach a motor to the focuser. With my older Megrez 80 (single speed focuser) I did this very easily by taking one focus knob off and installing a bracket with motor on to the shaft.

With the dual speed focuser, am I able to simply remove the knob from the side that only has one speed adjustment knob and not have the whole thing fall apart? I see the hex screw to undo the knob and perhaps then be able to pull it off, but am a bit weary that doing so the whole focuser and dual speed mechanism may spring apart. I'm not familiar with how dual speed focusers are constructed.

If I can simply take the knob off the single speed side of the focuser then attaching my focus motor should be very easy.

Any advice would be appreciated.

Thanks,
Roger.
