ADD GPS FOR THE MOST ACCURATE ALIGNMENT: Upgrade your Celestron computerised telescope with ultra-precise 16-channel GPS time, date, and location data

SAVE TIME ALIGNING YOUR SCOPE: Instead of entering the approximate time, date, and location into your hand control manually, SkySync obtains this information from orbiting global positioning satellites, saving you time in the field

GREAT FOR ASTROIMAGING: SkySync will improve your alignment—a difference you can see in your astroimages

WORKS WITH YOUR EXISTING TELESCOPE: Simply plug into your hand control or any available AUX port on your telescope mount. Works with all non-GPS Celestron computerised telescopes

PORTABLE POWER MADE FOR ASTRONOMERS: The perfect solution for most computerised telescopes, PowerTank Lithium features a 12V connection, 10 hours of battery life, an on-board red/white LED flashlight, USB ports, and more. Mounts directly to the tripod leg

SMALLER, LIGHTER, SAFER: Unique Lithium-Iron Phosphate (LiFePO4) chemistry makes this battery smaller and easier to maintain compared to sealed lead acid batteries, and safer than lithium cobalt batteries. Does not use toxic heavy metals

10 YEARS OF DEPENDABLE PERFORMANCE: Unlike other batteries with limited lifespans, PowerTank Lithium will be your companion for years of astronomy adventures; it is rated to withstand up to 2000 charge cycles
