Its optimum image circle is 28 mm, with a maximum IC of 44 mm.  The reduction factor is 0.95×, effectively shortening the exposure time and improving the shape of stars.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ef\/4 effectively reduced to f\/3.8\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003ef\/5 effectively reduced to f\/4.75\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003ef\/6 effectively reduced to f\/5.7\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: center;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eApplication：150mm - 600mm, f\/3 through f\/6 parabolic reflectors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eReduction Factor：0.95X\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eImage Circle：44 mm (maximum), 28 mm (optimal)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eLens：Triplet structure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eOuter Diameter：50.8 mm (2\")\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eBack Focus：56 mm (field-stop ring to the focal plane)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eLength：79.7 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eCoating：Full-surface multi-layer coatings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eWeight：0.22kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SharpStar","offers":[{"title":"Default Title","offer_id":39736160714865,"sku":"SHA-CRC2095","price":196.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/CRC2095.jpg?v=1776459062","url":"https:\/\/khanscope.com\/en-fr\/products\/sharpstar-2-0-95x-mpcc-coma-corrector-for-f-3-f-6-newtonians-crc2095","provider":"Khan Scope Centre","version":"1.0","type":"link"}
