The reduction depends on the spacing of the reducing lens between the objective and the image plane. This will vary depending upon the telescope used and the camera and accessories used, therefore the exact reduction factor is not a constant. Antares FR1 is a fully multicoated 25\/95 mm achromat and fits standard 1.25\" filter threads.\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAntares Model No:\u003c\/td\u003e\n\u003ctd\u003eFR1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptics Type:\u003c\/td\u003e\n\u003ctd\u003eFocal Reducer Lens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAperture:\u003c\/td\u003e\n\u003ctd\u003e25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length:\u003c\/td\u003e\n\u003ctd\u003e-NA-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Design:\u003c\/td\u003e\n\u003ctd\u003eDoublet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFL Reduction:\u003c\/td\u003e\n\u003ctd\u003e0.5x (approximate)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Antares","offers":[{"title":"Default Title","offer_id":31976166031473,"sku":"ANT-4201","price":23.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/focal-reducer125-05x.jpg?v=1776459327","url":"https:\/\/khanscope.com\/en-fr\/products\/antares-focal-reducer-1-25-0-5x-25-mm-multicoated-4201","provider":"Khan Scope Centre","version":"1.0","type":"link"}
