Orion 0.8x Focal Reducer for Refractor Telescopes

Some of the most picturesque celestial objects are too large to fit in the field of view of an imaging refractor and camera. What’s more, most objects in deep space are very faint and therefore challenging to image without taking very long exposures, increasing the potential for error. Our new Orion 0.8x Focal Reducer for Refractors addresses these obstacles by increasing your refractor telescope’s field of view while reducing the effective focal length by a factor of 0.8x, thereby providing a shorter, more optically “fast” focal ratio to increase astrophotography efficiency. Using the 0.8x focal reducer not only enables your refractor telescope to acquire a larger field of view, but also makes it capable of capturing bright, vividly detailed astrophotos in considerably less time.

The Orion 0.8x Imaging Focal Reducer’s fully multi-coated, 38mm clear aperture optics are housed in a sleek, all-machined, anodized aluminum body. Internal glare-threads provide maximum image contrast and brightness. It’s designed for use with any refractor telescope equipped with a 2” focuser, and requires 55mm of backfocus. Use with a DSLR and appropriate T-ring combination will not require use of any spacers. For use with a CCD astrophotography camera with less backfocus, we highly recommend using the Orion T-thread Spacer Ring Kit (sold separately) to achieve proper distance.

You can further enhance your astrophotos by using 2” imaging filters with the Orion 0.8x Imaging Focal Reducer since it is conveniently threaded for use with 2” filters. Unit weighs 6.2 oz.

Questions & Answers

Product Questions

I am looking at this reducer for use with my MallinCAM Universe mounted on an Explore Scientific 127mm refractor.

Is the camera thread a T-mount connection?

Is the focuser threaded to allow you to add a filter?

I have the Williams Optics GTF 102mm (older red model) and I was wondering if this flattener would work. I would need to focus with a DSLR.

I would like to know if this reducer will work well with my Explore Scientific 80 mm apo refractor and its Explore Scientific Field Flattener (2") . Thanks in advance.
