The objective features 2 ED lenses for good chromatic error correction. The apochromat is corrected for full-frame cameras.\u003c\/p\u003e\n\u003cp\u003eThe protective cap also offers good protection against stray light and is extendable. The large manual focuser holds even heavy cameras and allows for sharp focusing thanks to the \u003cb\u003emicrofocuser\u003c\/b\u003e. It has 2\", 1.25\" connections, and an M68x1 thread.\u003c\/p\u003e\n\u003cp\u003eThe scope of delivery includes an \u003cb\u003eadapter to M48x0.75\u003c\/b\u003e, ideal for all cameras with \u003cb\u003ea working distance of 55 mm\u003c\/b\u003e. Tip: to access the internal M48 thread for 2\" filters, unscrew the adapter, and it will be very easy.\u003c\/p\u003e\n\u003cp\u003eA specialist in photography, but \u003cb\u003ealso suitable for observation\u003c\/b\u003e: the ASKAR FRA400 has been designed for astrophotography. However, thanks to its comfortable working distance, 2\" star diagonals can also be connected. This turns the Astrograph into a beautiful spotting scope and telescope for astronomical observation and also for landscape observation. All common 2\" and 1.25\" accessories can be connected.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIncreased light intensity to f\/3.9\u003c\/b\u003e: the f\/5.6 aperture ratio is already relatively fast. But an even faster optic is often desired. With the optional reducer, you can increase the light intensity from f\/5.6 to f\/3.9 and thus halve the exposure time. The focal length is reduced to 281 mm.\u003c\/p\u003e","brand":"ASKAR","offers":[{"title":"Default Title","offer_id":52803705831767,"sku":"80164","price":1312.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/Askar-Refractor-apocromatico-AP-72-400-FRA400.jpg?v=1771235810","url":"https:\/\/astrotelescopios.com\/en-uk\/products\/telescopio-refractor-apocromatico-ap-72-400-fra400","provider":"Astro Telescopios","version":"1.0","type":"link"}
