Focal Reducers

This superb 0.5x focal reducer has been designed to be used with a wide range of modern CCD cameras and eyepieces. The lens has a female 1.25" eyepiece filter thread and can be attached to camera and eyepiece nose barrels to achieve a 50% increase in field of view.

This superb fully multi-coated double-element focal reducer takes advantage of the latest computer aided design techniques to achieve the highest standards of performance to dramatically increase the field of view

This superb fully multi-coated multi-element focal reducer takes advantage of the latest computer aided design techniques to achieve the highest standards of performance set by the brand leaders at a fraction of the cost.

The Meade 4-element, multi-coated f/6.3 Focal Reducer threads on to the rear cell of any Meade LX-series mirror-lens telescope or to other SCT brands and reduces the telescope's focal ratio by a factor of 0.63

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 Lightwave 0.6x focal reducer gives an 0.6x reduction in F-Ratio for faster exposure times, as well as a correspondingly wider field for astro-photography. Designed primarily for refractor telescopes of F6 or longer focal ratios.

This high quality reducer for photographic from Vixen is used is designed to shorten the effective focal length of your Vixen ED81S, ED103S or ED115S refractor telescopes.

Designed for serious Astro-Imagers. Optimised for the Evostar ED PRO range, this superb quality accessory effectively reduces the telescope’s focal length by a factor of 0.85x and provides much improved field-edge correction.

Designed for serious Astro-Imagers. Optimised for the Evostar-150ED PRO, this superb quality accessory effectively reduces the telescope’s focal length by a factor of 0.85x and provides much improved field-edge correction.

Designed for serious Astro-Imagers. Optimised for the Evostar-72ED PRO, this superb quality accessory effectively reduces the telescope’s focal length by a factor of 0.85x and provides much improved field-edge correction.

A common limitation that plagues owners of most popular Schmidt-Cassegrain telescopes is the narrow field size and high magnifications produced by their slow optical system (typically, f/10).

Brand new 0.8x adjustable reducer flattener by William Optics to suit the Zenithstar 73 series. Comes complete with integrated rotator and 2" filter holder.

The focal reducer for the AX103S Refractor telescope is designed for APS-C format cameras. It reduces focal Length by 0.7x, changing to f/5.6.

This Vixen Focal Reducer takes the standard 1800mm (f/9) focal length down to 1278mm (f/6.4). Increasing the field of view and decreasing the exposure time to dramatically increase your density or signal to noise ratio.

Vixen's Reducer HD is used with the VC200L Optical tube. The focal length is reduced to 0.77x. This covers the photographic field of a DSLR camera with APS-C image sensor for prime focus astrophotography.
