From all the telescopes that are part of the StarSense series from Celestron this particular telescopes is the one with the largest aperture while still being a refractor. Which means it’s suitable for beginner who don’t want to worry about a steep learning curve when starting to use it as well as low maintenance while also being able to gather enough light to see a multitude of sky objects with increased clarity.

And the most important feature of all, the ability to “connect” with the StarSense app in order to easily point toward the object you want to observe. One of the most difficult things for a new star gazer is the ability to find object all by their own. So the StarSense Sky Align patented technology from Celestron takes that pain away while also acting as your personal and all-knowing guide to the night sky.



  • Great for beginners
  • Easy to setup and easy to use
  • StarSense technology for easy finding of the stars


  • You will need a smartphone to download the StarSense app
