The Celestron SkySync adds GPS (Global Positioning System) accuracy to all non-GPS go-to computerized Celestron telescopes. It works with both altazimuth and German equatorial mount Celestrons, and is powered by your scope (no batteries needed).
SkySync starts you observing faster by using GPS satellite transmissions to accurately enter the necessary time, date, and observing location information into your scope's NexStar computer automatically while you set up the rest of your observing gear. There's no manual time, date, or location data input on your part. SkySync lets you spend more time observing and less time getting ready to observe.
SkySync is a great help if you travel to several different observing sites, assuring faster and more accurate alignment on the sky at each site with no guesswork. If your view of the north from your backyard observing site is obstructed by buildings or trees, SkySync will make short work of accurately aligning your scope on the skies. You won't have to guess if you're pointing at Polaris.
SkySync comes with two Velcro straps that let you mount it on the tripod leg of your scope. A 13" strap mounts SkySync on a CGE Pro mount, while a separate 10" strap works with all other Celestron mounts. A cable from the SkySync module plugs into your scope's hand control or accessory port. You'll need to do a rough polar alignment if your scope is a German mount model. No alignment is needed with an altazimuth mount scope.
SkySync's16-channel GPS receiver determines its latitude and longitude on earth from the GPS satellite signals, triangulating your location with an accuracy measured in meters. It determines the time and date from the GPS satellite signals with an accuracy measured in fractions of a second.
Once SkySync knows precisely where and when on Earth it is, it relays that information to your scope's computer. Your scope's NexStar computer needs that information to align on the heavens. The more accurate the time and location information you can give to your scope, the more accurate your scope's alignment on the sky. SkySync guarantees a very high accuracy and a no-guesswork scope set-up.
