The Revelation 0.5x Focal Reducer 1.25" will effectively halve the focal length of a telescopic system when used in conjunction with standard 1.25" eyepieces and photographic accessories. Fully multicoated and capable of accepting 1.25" threaded accessories (filters, polarisers etc.) this useful accessory will also help expand the field of view of video eyepieces and cameras, including the Orion Starshoot Deep Space Video Camera II. Not recommended for short focal ratio systems. Made in by GSO for Revelation Astro - 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 male and 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. Basically the lens has the effect of halving the focal length of the telescope.

This super quality lens features full edge blackened optics and full multi-coating for increased contrast.

Supplied in a plastic storage case.

The exact degree of focal reduction achieved with any given set-up depends somewhat on the precise position of the FR relative to the imaging chip in the case of CCD cameras and the optics when used with eyepieces. Thus the judicious use of extension tubes and carefully positioned filters can squeeze a great deal of versatility out of these excellent quality observing and imaging aids.

An indispensable CCD imaging aid!
