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, you will likely need some spacer rings to achieve the 55mm distance between the Reducer and the camera's sensor.
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.
