The voltage from the focuser port of the LX200 is 18 volts. I am running an
NGF-S focuser, and I dropped the voltage to 9 volts. This keeps the NGF-S from
speeding past the desired focus position. Here is a rough schematic. I'll
send a gif of the schematic via private e-mail, as attachments are off-limits
here.

I think I got the schematic from Doug Clapp's website.
