What Celestron telescopes does it work with?
The short answer is, any Celestron telescope that is equipped with an AUX port. This includes: • NexStar 5i/8i • NexStar 8i Special Edition • CGE Series • AS-GT Series (with Celestron #93965 AUX port accessory kit) • SLT Series Note that while the NexStar GPS Series and CPC Series telescopes do have an AUX port, the StarDate GPS Adapter is not intended to be used with either of these series, since they already have built-in GPS receivers. Early model NexStar 5/8 (non-“i” telescopes) cannot be supported, because they lack an AUX port as well as firmware GPS support in the hand controller. The serial port on the bottom of the hand controller is not an AUX port, and cannot be used to enter time/date/location in these models. Also please note that the Celestron GT series and the Orion StarSeeker telescopes do NOT have an AUX port, and therefore are not supported. You CANNOT add an AUX port to these telescopes by using the Celestron #93965 AUX port accessory kit.
