These telescope designs place great emphasis on optical, as well as mechanical quality making them the perfect instrument for Astrophotography and the product designation 'FRA' stands for a Refractor telescope with an integrated corrector element for a flat and corrected field of view.\u003cbr\u003e\u003cbr\u003eThe Askar FRA300 is a 5-element Petzval apochromat with a 300mm focal length, f\/5 and 60mm aperture. There are 2 ED glass elements built into the lens for good correction of chromatic aberration. This APO is also corrected for cameras up to a full frame sensor.\u003cbr\u003e\u003cbr\u003eThe dew shield also provides good protection against stray light and is retractable. The large focuser holds heavy cameras and the dual-speed gearing allows very precise focusing. \u003cbr\u003e\u003cbr\u003eThere are T2, M48 and M54 threads also available for different connection types. The working distance is optimized for all popular cameras, from mirrorless systems and DSLR's to astro cameras (CMOS and CCD).\u003c\/p\u003e\n\u003cp\u003eWhile this telescope was designed for Astrophotography, it is also suitable for visual observations too.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpec:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAperture: 60mm\u003c\/li\u003e\n\u003cli\u003eFocal length: 300mm\u003c\/li\u003e\n\u003cli\u003eFocal ratio: f\/5\u003c\/li\u003e\n\u003cli\u003eTelescope type: 5-element (quintuplet) apo with 2-element ED lens\u003c\/li\u003e\n\u003cli\u003eTransport length: 300mm\u003c\/li\u003e\n\u003cli\u003eWeight: 3.15kg\u003c\/li\u003e\n\u003cli\u003eCamera side connection: M76x1 M54x0.75 male thread, M48x0.75 male thread and T2 male thread\u003c\/li\u003e\n\u003cli\u003eDrawtube travel: 20mm\u003c\/li\u003e\n\u003cli\u003eFilter thread: 2\" filter thread (M48x0.75) is integrated in the camera adapter (accessible after unscrewing the adapter)\u003c\/li\u003e\n\u003cli\u003eWorking distance: 45-65mm from the T2\/M48\/M54 connection thread and 55-75mm from the M76x1 external thread\u003c\/li\u003e\n\u003cli\u003eDew shield diameter: 92mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eWhats included:\u003c\/em\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eTelescope OTA\u003c\/li\u003e\n\u003cli\u003eCNC tube rings\u003c\/li\u003e\n\u003cli\u003eGP\/EQ5 style dovetail bar \u0026amp; Handle\u003c\/li\u003e\n\u003cli\u003ePhoto adapter to M48, M54 and T2\u003c\/li\u003e\n\u003cli\u003eFinder shoe (mounted)\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003col\u003e\u003c\/ol\u003e","brand":"Askar Sharpstar","offers":[{"title":"Default Title","offer_id":48163083878735,"sku":"FRA300","price":1320.84,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/files\/AskarFR300TelescopeAstrography_4.jpg?v=1704820884","url":"https:\/\/www.horizonastronomy.ie\/en-ro\/products\/askar-fra300-60-apo-quintuplet","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
