I am powering my CGEM mount from a Pegasus Pocket Power Box. The 12V power cords are not threaded but the power plug receptacle on the CGEM mount will take a threaded plug. (I snagged the cord and pulled it out of the mount the other night powering it down.) I bought the mount used so I do not have any original power cords with it. It looks like Celestron sells the power supply for the CGEM with the threaded end but it's about $70 and I can't use it with the Pegasus anyways. That seems an outrageous price for a 12v power adaptor/plug. Is there a reasonably priced option out there or I can wire it myself but I'm not sure where to buy the threaded plug end.
