About the Star GPS Package...
Add GPS to your telescope! The new 65-channel Star GPS-NX02 receiver works with the Astro-Physics GTO, Celestron NexStar, Losmandy Gemini, Meade 497/497EP Autostar, Audiostar, LX200 Classic, LX200GPS, LX200ACF, RCX400, Orion Atlas/Sirius GoTo, Sky-Watcher SynScan, Vixen StarBook and StarBook Type-S.
Imagine if your telescope could access the Global Positioning System so that it always knew when and where you were observing from. No more checking your watch, looking up site coordinates or fiddling with the keypad to enter the date, time, latitude and longitude. StarGPS uses a single cable to connect your telescope to the GPS receiver and automatically input these values... making your telescope setup much easier and more precise!
