StarGPS NX for Meade 497 AutoStar and AudioStar Telescopes

StarGPS NX for Meade 497 AutoStar/AudioStar Telescopes

Add GPS to your Meade 497 Autostar/AudioStar Telescopes!

Imagine the possiblities 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. No more looking up site coordinates or fiddling with the keypad to enter the date, time, latitude and longitude. StarGPS has solved your problems! It utilizes a single cable to connect your telescope to a GPS receiver smaller than a computer mouse and automatically input these values - making your telescope setup much easier and more precise!

StarGPS-NX is a "plug-and-play" solution for use with the Celestron NexStar, Meade Autostar-AudioStar, LX200 Classic and Losmandy Gemini telescopes. It includes a GPS-NX02 receiver and the proper cable for your telescope. No software is required since the GPS receiver outputs commands and data the telescope already understands. Simply connect the GPS to your telescope, turn on the scope, and watch the GPS LED indicate:

Power ON
Location Determined
Setup Complete

The GPS-ASTAR cable, which connects the GPS Receiver to a 495/497 Autostar/AudioStar. The PS/2 plug connects to the GPS. The short cable plugs into an AUX port on the telescope (to power the GPS). The long cable plugs into the controller so it can receive data from the GPS.

IMPORTANT: The following handset software versions have a bug in at least one LX200 command such as "set latitude" or "set date": Autostar 497 (27, 30, 35, 40, 41, 42), Autostar 497EP (all versions), Audiostar (versions prior to A3S4). If your handset displays any of these version numbers (eg. [40E]) you must update your handset using StarPatch, see With the free trial version of StarPatch you must uncheck the "GPS Setup" option before doing an "Update Handset". You can check the software version by watching the top right corner of the handset display just after turning on the power.

What I have always liked about all the StarGPS that they are simple: no setup required, no CD to download, no drivers, no fuss. Just plug it in and it does the work for you...These are products that work, and once installed you can forget about them and enjoy the night sky. Then, next time you are ready to fire up the telescope again....StarGPS NX02 is ready and waiting.

StarGPS NX does what it says

Works great with my older model Meade LX 90 telescope!

Add GPS to an LXD75

I've been using one for about 5 years - plug it in and my LXD75 now gets GPS coordinates and timing. Works transparently and really easy!
