Your card will only be charged once item ships.
The Opticstar 1.25" Imaging Focal Reducer will fit to any CS or C-mounted camera and has been designed solely for imaging. The focal reducer consists of a two lens cemented system for better correction, optics are fully broadband multi-coated. The two lens system sits is a metal cell that is threaded for filters.
The Opticstar imaging focal reducer can be used to reduce the focal length of the telescope in conjunction with an extension, i.e. 5mm C-rings. When used photographically the focal reduction will vary depending on the distance from focal reducer optics to the camera sensor. The Opticstar Imaging Focal Reducer comes with no C-rings offering a focal reduction of F0.73 when used with a C-mount camera.
