    Orion 0.8x Focal Reducer for Refractor Telescopes

    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. Whatƒ????????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 telescopeƒ????????s field of view while reducing the effective focal length by a factor of 0.8x, thereby providing a shorter, more optically ƒ????????fastƒ???????? 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 Reducerƒ????????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. Itƒ????????s designed for use with any refractor telescope equipped with a 2ƒ???????? 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 2ƒ???????? imaging filters with the Orion 0.8x Imaging Focal Reducer since it is conveniently threaded for use with 2ƒ???????? filters. Unit weighs 6.2 oz.

    Questions & Answers

    Ask a Question
    • 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.

      This is a reducer, not a flattener. There is no guarantee that this would work properly with the GTF102, though I guess it would be okay for up to APS-C format or smaller.

    • 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?

      The thread on the camera side of this reducer is T thread, and the back focus is 55mm, so you may need to add a spacer or two between your camera and the reducer to get the spacing correct. The 2" barrel of the reducer has a 48mm thread that will accept

    • 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.

      Using this reducer with the ES field flattener will not work properly and the image will not be able to come to focus. There are other reducer-flatteners that would produce the results that you are looking for. Please give a call at 1-800-483-6287 or emai

    • Is it water resistant?

      Yes, this watch is water resistant.

    • Will this work with ES AR152 Refractor? i.e. 988mm/F6.5 Thanks

      This reducer will reach focus with a camera at proper 55mm spacing behind it, but you may not have a perfectly flat field, and you will still have to correct for chromatic aberration some other way. This reducer cannot be used visually.
