What are the specifications for an AC adapter that will work with Celestron’s GoTo mounts?

Most of Celestron’s GoTo mounts will work with an AC adapter that has these characteristics:
  • 12VDC output
  • 2.5 amps (2500 milliamps) current output
  • Inside tip positive
  • Inside diameter is 2.1 mm
  • Outside diameter is 5.5 mm
  • Jack length 10-15 mm

Some smaller mounts might work with adapters with less amperage output.  Our largest mount, the CGE Pro, works best with adapters delivering 5 amps maximum or higher.
