Feature
●Converts f/10 optical system to faster f/6.3 for a significantly wider field of view.
●Reducer shortens the effective focal length of Schmidt-Cassegrain telescope optical system by 37%.
●This combination focal reducer and field corrector lens accessory works with all Celestron 5", 6", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes.
●Four-element, fully multi-coated optical design with 41mm clear aperture.
●This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality.
Description
- This combination focal reducer and field corrector lens accessory works with all Celestron 5", 6", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes.
- This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6.3 for C5, C6, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope.
- If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3.
Advantages in a nutshell
- Converts f/10 optical system to faster f/6.3 for a significantly wider field of view.
- Reducer shortens the effective focal length of Schmidt-Cassegrain telescope optical system by 37%.
- Four-element, fully multi-coated optical design with 41mm clear aperture.
