The FRA series is mainly used for astrophotography.\u003cbr data-mce-fragment=\"1\"\u003eThe ASKAR FRA400 is a Petzval 5-element Apochromat with 400mm focal length, f\/5.6 focal ratio and 72mm aperture. 2 ED glasses are installed in the front lens for improved colour correction. This APO is also suitable for cameras up to full frame sized sensors.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe dew cap also provides good protection against stray light and is retractable. The large focuser also holds heavy cameras and allows for precise focusing thanks to the microfocus adjustment wheel. A 2\", 1.25\" and an M68x1 thread are available for additional connections. Also included with this telescope is an adapter up to M48 x 0.75, which is ideal for all cameras with a standard 55mm working distance. \u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cem\u003eNote: To access the female M48 thread for 2\" filters, unscrew the adapter.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpec:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAperture: 72mm\u003c\/li\u003e\n\u003cli\u003eFocal length: 400mm\u003c\/li\u003e\n\u003cli\u003eFocal ratio: f\/5.6\u003c\/li\u003e\n\u003cli\u003eTelescopic type: 5-Element Quintuplet Apo with 2-Element ED Lens\u003c\/li\u003e\n\u003cli\u003eTransport length: 317 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 2.56 kg\u003c\/li\u003e\n\u003cli\u003eConnection camera side: M68x1 male thread, 2\" and 1.25\" receptacle\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\u003ePhoto adapter: M68x1 female thread - M48x0.75 male thread - length 63.5mm\u003c\/li\u003e\n\u003cli\u003eHoles in pipe clamps: M6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e5-element quintuplet design with corrector\u003c\/li\u003e\n\u003cli\u003eTwo ED lens's for very good correction of color\u003c\/li\u003e\n\u003cli\u003e44mm image circle with full illumination and correction\u003c\/li\u003e\n\u003cli\u003eWorking distance for visual observation or focal length reduction\u003c\/li\u003e\n\u003cli\u003eStable 3\" RAP focuser with micro reduction gear and 360° rotation\u003c\/li\u003e\n\u003cli\u003e2\" and 1.25\" connector as well as M68x1 male thread for screw on adaptions\u003c\/li\u003e\n\u003cli\u003eLong adapter from M68 to M48x0.75 Camera connection with 2\" filter thread (accessible after unscrewing the adapter)\u003c\/li\u003e\n\u003cli\u003eFlexible GP\/EQ5 level dovetail bar with photo tripod connection and carrying handle with flexible slotted hole\u003c\/li\u003e\n\u003cli\u003eFinder shoe for standard viewfinder holder\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cem\u003eWhats included:\u003c\/em\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003col\u003e\n\u003cli\u003eCNC tube rings\u003c\/li\u003e\n\u003cli\u003eGP\/EQ5 level dovetail bar\u003c\/li\u003e\n\u003cli\u003eCarry Handle\u003c\/li\u003e\n\u003cli\u003ePhoto adapter to M48x0.75\u003c\/li\u003e\n\u003cli\u003eFinder shoe (mounted)\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Askar Sharpstar","offers":[{"title":"Default Title","offer_id":43634011013363,"sku":"FRA400T","price":1417.01,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/products\/Askar-FRA400-APO-Telescope_5.jpg?v=1675799142","url":"https:\/\/www.horizonastronomy.ie\/en-hr\/products\/askar-fra400-72-apo-quintuplet","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
