Celestron power supply cable

[04Stefan07 (Stefan)]

Hi everyone,

Where can I get a cable to hook my Celestron to a power supply? I am asking to double check because I don't want to fry my electronics.

Here is an extract from the manual of my scope.

Input voltage: 12v dc nominal
Power supply req: 12 vdc-750mA (tip positive)

An online Australian store, or store I can go to locally would be great.

Thanks.
