Feature
●This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality.
●Four-element, fully multi-coated optical design with 41mm clear aperture.
●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.
●Reducer shortens the effective focal length of Schmidt-Cassegrain telescope optical system by 37%.
●Converts f/10 optical system to faster f/6.3 for a significantly wider field of view.
Description
Astromania f6.3 Reducer Corrector for C Series Telescopes
- Apply to: C5, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope.
- Using for: F/6.3 Reducer shortens the effective focal length of 37% and increase the image field.
- Four-Element For Better Correction
Astromania design the four-element, fully multicoated f/6.3 Reducer/Corrector. 4 lenses- cemented together and coated, increase the light transmittance, the image is brighter and clearer. Results are amazing both visually and photographically.
- Equivalent Focal Length
High-precision fully multi-coated optical glass lens, spherical is minimized, so that the observed image is flat, closer to the original object.
