The Celestron Travel Scope 70 has a front lens diameter of 70 mm and a focal length of 400 mm. A telescope with these specifications works well for terrestrials observations, both for daytime and nighttime. Due to its size, however, it has a very limited use for astronomical observation. Note that the telescope showed signs of chromatic aberration, like any other low cost telescopes.
