Celestron StarSense AutoAlign for Sky-Watcher Mounts

Celestron StarSense AutoAlign for Sky-Watcher Mounts

Due to high demand and global product shortages due to the pandemic, please call for availability.

Automatically align your computerized Sky-Watcher mount with the StarSense AutoAlign.

There is no need to identify or locate any stars in the sky – StarSense will automatically align your telescope, so you can begin observing in minutes. The StarSense features plug and play compatibility with Sky-Watcher SynScan mounts.

The accessory replaces the SynScan hand controland uses the Celestron StarSense hand control with the StarSense camera. Comes with the mounting bracket that is compatible with most Celestron and Sky-Watcher optical tubes.

3 AUX port accessories: Supports StarSense and the optional GPS accessory. The StarSense is lightweight and easy to attach with the included tripod strap.

Before StarSense, using a computerized telescope required a lengthy alignment process of finding and centering at least two bright stars in the telescope's eyepiece. But StarSense automatically aligns itself, no user input needed. With StarSense, you become an instant astronomer, even if you've never used a telescope before.

The StarSense Accessory includes a small digital camera that attaches to the telescope’s optical tube, along with the new StarSense hand controller which is more powerful than the NexStar and NexStar+ hand controls. Just set up the accessory, push the Align button on the hand controller, and StarSense starts capturing and comparing images of the night sky against its internal database of 40,000 celestial objects. In about three minutes, StarSense will gather enough information to triangulate its position and align itself. Then, press the Sky Tour button: StarSense will automatically slew to all the best stars, planets, galaxies, and more based on your exact time and location.

Even the most advanced telescope users will love using the affordable StarSense Accessory. StarSense replaces expensive software used for Advanced Mount Modeling, providing superior pointing accuracy from horizon to horizon. Users can add as many calibration stars as desired to give their telescope mount a new level of accuracy.

Users of equatorial mounts need to perform a polar alignment first, which is easy to do, thanks to Celestron's All-Star Polar Alignment built into the hand control.
