It’s a high quality product and it's easy to use. The coma corrector is designed for APS-C imaging circles (28mm), suitable for Newtonian reflectors with focal ratios between f\/3 and f\/6, and aperture size from 150mm to 600mm.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1594\/4815\/files\/NGC2264.jpg?v=1666889902\u0026amp;width=700\"\u003e\u003c\/div\u003e\n\u003cbr\u003e\n\u003cp\u003eDue to the reduction factor of 0.95x, the coma corrector can reduce the focal ratio from f\/4, f\/5, and f\/6 to f\/3.8, f\/4.75, and f\/5.7. Effectively shortening the exposure time. Also, it can improve the star shapes. The diameter of stars in the center of the field can be limited within 10um.\u003c\/p\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1594\/4815\/files\/157779140427.jpg?v=1666889955\u0026amp;width=700\"\u003e\u003c\/div\u003e\n\u003c!-- split --\u003e\n\u003cul\u003e\n\u003cli\u003eDue to the reduction factor of 0.95x, exposure times are shortened\u003c\/li\u003e\n  \u003cli\u003eThe coma corrector is designed for APS-C imaging circles (28mm), suitable for Newtonian reflectors with focal ratios between f\/3 and f\/6, and aperture size from 150mm to 600mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- split --\u003e\n\u003cul\u003e\n\u003cli\u003eSharpstar CRC2095 Coma Reducer Corrector\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sharpstar \/ Askar","offers":[{"title":"Default Title","offer_id":67889678287161,"sku":"yqv1793414157901","price":149.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/5281\/2601\/files\/sharpstar-crc2095-coma-reducer-corrector_1.jpg?v=1793414163","url":"https:\/\/auroradogboots.shop\/products\/sharpstar-crc2095-coma-reducer-corrector","provider":"My Store","version":"1.0","type":"link"}
