The Celestron Travel-scope is a refractor-style telescope, which means it uses glass lens as its objective to bend (or refract) light. Refractor telescopes have steady, sharp images and stay cleaner for longer.


A telescopes aperture refers to a small hole in the lens which allows light to travel into the telescope.

You can adjust the aperture to change how the light affects your image; more light may make it harder to see objects during the day, but it will make it easier when it gets darker. The Celestron Travel-scope has a 2.76 inch aperture (70 mm).

Focal Length

A telescope’s ‘focal length’ refers to the distance between your telescopes primary lens and the point where light comes into focus.

Your telescope’s focal length will help you determine the telescopes magnification powers. The Celestron 21305 comes with a 400-mm focal length.
