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.
In 2021, the objective lens of this telescope has been repurposed as a DIY focal reducer.
