Bird-Jones telescopes are catadioptric, meaning that the light travels the optical tube two times instead of one.
The design is challenging to pull off. That is why if you are buying a “low-priced” catadioptric telescope, you should know that the telescope is probably not legitimate. This the case with Celestron 114LCM.
The corrector lens is low-quality, and the primary mirror is spherical, which is as cheap as it gets. Collimating this telescope is a pain, and trying to get a crisp focus at high magnifications is even worse.
I won’t talk about high-magnification or low-magnification performances because it is not worth it. Getting color accurate and crisp images with the Celestron 114 LCM is impossible.
