Sharpstar 2\" 0.95x coma corrector is designed for APS-C imaging circles (28mm), suitable for Newtonian reflectors with focal ratio between f\/3 and f\/6, and aperture size from 150mm to 600mm.\u003cbr\u003e- The reduction factor is 0.95x, thus it can reduce the original f\/4, f\/5 and f\/6 respectively to f\/3.8, f\/4.75 and f\/5.7, effectively shortening the exposure time. Besides, it can improve the star shapes. The diameter of stars in the center of the field can be limited within 10um.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecification:\u003c\/b\u003e\u003cbr\u003e- Application: 150-600mm, f\/3-3\/6 parabolic reflectors\u003cbr\u003e- Reduction factor: 0.95×\u003cbr\u003e- Image circle: 44mm(maximum), 28mm(optimal)\u003cbr\u003e- Lens: triplet structure\u003cbr\u003e- Outer diameter: 50.8mm(2\")\u003cbr\u003e- Back focus: 56mm(starting from the field-stop-ring to the focal plane)\u003cbr\u003e- Length: 79.7mm\u003cbr\u003e- Coating: full-surface multi-layer coatings\u003cbr\u003e- Weight: 0.22kg\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Coma Corrector\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.byimg.com\/catalog\/90707\/90707-1.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.byimg.com\/catalog\/90707\/90707-2.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.byimg.com\/catalog\/90707\/90707-3.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.byimg.com\/catalog\/90707\/90707-4.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Sharpstar","offers":[{"title":"Default Title","offer_id":40829779574833,"sku":"90707","price":219.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/7079088226353_watermarked_0.jpg_0.png?v=1767579147","url":"https:\/\/www.thanksbuyer.com\/es\/products\/sharpstar-2-0-95x-mpcc-coma-corrector-astronomical-accessory-for-150mm-600mm-newtonian-reflective-astrographs","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
