Astromania 1.25" 0.5X Reducer Corrector - C-Mount Standard for C Or CS Mount CCTV Type Cameras with Telescopes - Reduces The Focal Length for Visual and Photographic Use
85mm focal length, reduction factor of about 0.5X, depending on spacing. 0.5x focal reducer effectively halves the focal length of a telescope, enabling lower magnification.
Mounting threads - 1.25" filter thread (28.5x0.75 MM) on one sides, the opposite end of this adapter has a C-Mount (1 inch diameter with 32 threads per inch) standard for C or CS mount CCTV type cameras with telescopes.
A wider field of view, and shorter exposure times for astrophotography. 2 lenses for better correction - cemented together and coated, black-anodized aluminum housing.
Free light transmission - 22.5mm lens aperture. Can be used with additional spacers (available separately) to achieve further focal reduction.
Intended for use with with longer-focal-ratio telescopes and eyepieces of narrow to moderately-wide apparent fields of view.
