Used for astrophotography, it reduces exposure time by a factor of 3.\u003c\/p\u003e\n\u003cp\u003eCelestron doesn’t offer a f\/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f\/6.3 Reducer\/Corrector. Results are amazing both visually and photographically.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003eThe #94175 Reducer\/Corrector Lens is not compatible with Celestron EdgeHD optical systems.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":48053910929667,"sku":"U2603-MP-94175","price":110.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1979\/5379\/files\/original-451.jpg?v=1777757212","url":"https:\/\/milehighastro.com\/products\/used-celestron-focal-reducer-field-corrector-f-6-23","provider":"Mile High Astronomy","version":"1.0","type":"link"}
