Availability: Immediate Dispatch

  • Enables automatic alignment of a wide range of Celestron computerised telescopes
  • Automatically aligns your telescope, so you can begin observing in 3 minutes or less
  • Provides advanced mount modelling—align on numerous stars throughout the sky for extremely precise GoTo pointing accuracy
  • StarSense hand controller included

The Celestron StarSense AutoAlign removes the "chore" of having to do the alignment part of the telescope's set up procedure. In a way. it allows you to become an "instant astronomer", even if you’ve never used a telescope before.

Just set up the StarSense accessory, push the Align button on the hand control, and StarSense begins capturing and comparing images of the night sky against its internal database. In about three minutes, it's gathered 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 currently visible in the night sky.

How it Works


The self-alignment technology behind Celestron's award-winning SkyProdigy series is now available for most of Celestron's current computerised telescopes and compatible with many older models as well (see compatibility list).
A small digital camera takes the place of your finderscope and attaches using one of two provided mounting brackets. The included StarSense hand control, with a database of over 40,000 celestial objects, takes the place of your NexStar hand control. The camera automatically captures a series of images of the sky. StarSense identifies the stars in the images, matching them to its database. Once a positive match is confirmed, StarSense calculates the coordinates of the centre of the captured image, thereby determining exactly where the telescope is pointed.

Before StarSense, using a computerised telescope required a lengthy alignment process of finding and centring at least two bright stars in the telescope’s eyepiece. But StarSense automatically aligns itself with minimal user input. Just enter your time, date, and location and let StarSense do the rest!

Advanced Mount Modeling

Even the most advanced telescope users will love using StarSense AutoAlign. This affordable accessory replaces the expensive software usually used for advanced mount modeling.

With built-in mount modeling, you'll get superior pointing accuracy from horizon to horizon. When your alignment needs to be perfect, add up to 10 additional calibration stars to achieve a new level of accuracy, great for locating objects in the camera’s field of view for astroimaging.

The StarSense camera has field of view: 6.88º x 5.16º
