Features of the Orion 0.8x Focal Reducer for Refractor Telescopes - Orion Telescopes

Reduces an astrophotography refractor's effective focal length by a factor of 0.8x, providing a shorter, more optically fast focal ratio. PRODUCT PAGES: For our US and Canadian customers - http://bit.ly/2a8yKxZ 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.
