Feature

●0.5x focal reducer cuts the telescopes focal length in 0.5 times of originals to get a wider field of view
●Fully anti-reflection coatings on all air-glass surfaces for increased contrast
●The focal reducer is great for visual use for a bigger FOV and is indispensable when CCD imaging
●Fully metal structure design;both the ends of the interface part is 28.5x0.6 thread
●Directly connect the interface to the eyepiece;there is a very good performance in both visual and photography

Description

1.25" 0.5x Focal Reducer for Telescope Eyepiece Photography and Observing

A wonderful tool for astrophotography telescopes: reduce exposure time and simplify astrophotography; suitable for shooting. Capture wider field of view; the focal reducer is good for visual use for a bigger FOV and is indispensable when CCD imaging.

Full metal aluminum alloy

The case is made of metal, which better protects the product itself and prolongs its service life.

Fully Multi-coated Optics

FMC optical glass design 2 pieces of optical design, increase the light transmittance; the image is brighter and clearer. 2 element optical design with fully multi-coated optics. Fully anti-reflection coatings on all air-glass surfaces for increased contrast.

1.25" Filter Screw-in Thread - Fits for any standard 1.25" telescope eyepiece

Fully threaded to minimize reflections. Blackened edges and blackened interior to reduce scattering of stray light and maximize contrast.

Fully metal for long time using. Besides the male thread, it also has female thread at the rear end to fit filters etc.

0.5X focal reducer is threaded for attaching to a C-Mount standard for C or CS mount CCTV type cameras with telescopes.

Screw the reducer into C or CS mount CCTV type cameras and so double the size of the photographic image field. This lets you take images of much larger areas of the lunar surface.

for example. The reducer is also great for taking videos of the Moon using your webcam.

You can obtain even larger image fields with your astronomy webcam if you attach an extension tube (e.g. 25mm) between the reducer and camera.

Increase the image field of your web camera.

More lens speed.

Use the reducer visually with an eyepiece.

Also ideal for video astronomy.

Record large areas of the moons surface.
