Re: Refurbishing old Edmund Medium Mount
Does the manual state what the tooth count is on the different axis?
That would help greatly but in the meantime you could look at OneStep or Avalon for replacement tracking motors or even
There are couple other retailers but I cannot think of them at the moment.

That telescope is a thing of beauty!
There are a number of suppliers that sell various retrofit telescope mount motor drives but a non generic replacement for your Edmund would be difficult to find.
As for using it you will need to set its latitude and polar align it first. Let us know your level of experience with these and with setting circles, right ascension and declination.

Re: Refurbishing old Edmund Medium Mount
The brass gear inside has 96 teeth and the motor is 120V 1/15 RPM and rated at 5 W.
In terms of experience level, I am pretty comfortable with this stuff, just not this mount yet. The declination and
I have attached a pic of the actual mount that I have (counter weights removed while I'm working on it.) Mount is in perfect shape other than the motor. Thanks for your help everyone.

Re: Refurbishing old Edmund Medium Mount
There is a company in Germany that custom makes mount motors, I will see if I can find them.
Since Edmund is still around you could send a email or call, they may still have information on who supplied the motors
and possible have a manual in their archive.
There is also Astro-Gadget from Ukraine
