Re: [ATM] motor drive question

Hi Eric,

Do you know how fast the Orion motor turns?  It's probably one revolution
every 15 minutes which matches the rate needed for a 96 tooth worm gear. 
Chances are that the rotation speed for the Scotch mount is 1 RPM so you
will need to gear-up the Orion's speed.  It would probably be easier to
get a 1 RPM motor and depending on the motor type, you might be able to
use the Orion controller.
