🔭 Unlock dual telescope power — see more, shoot faster, and never miss a cosmic moment!
The Celestron Focal Reducer & Field Corrector is a precision accessory that reduces your Schmidt-Cassegrain telescope’s focal length and f/ratio by 37%, converting an f/10 system to f/6.3. This upgrade broadens your field of view, shortens exposure times for astrophotography, and enhances low-light terrestrial imaging. Fully multi-coated lenses ensure maximum light transmission, while compatibility with standard accessories keeps your setup flexible. Lightweight and easy to install, it’s backed by a 2-year warranty and decades of Celestron expertise.

| Focal Length Description | The original focal length of the telescope, before using the reducer corrector, is not explicitly mentioned in the provided information. However, it can be inferred that for an f/10 system, the reducer corrector reduces the focal length by 37% to make it an f/6.3 system. Thus, if the focal length of the f/10 system is F, then the focal length after using the reducer corrector would be 0.63F (f/6.3… |
