Introduced here is the 0.8x reducer, which is optimized for the Askar 103APO, and can provide more possibilities for telescope use.\u003cmeta charset=\"UTF-8\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe 0.8x reducer can bring Askar 103APO's focal ratio down to F5.4. This is a standard reducer with field flattening capabilities as well. A shorter focal ratio allows the OTA to have a wider field of view and faster exposure times, making it suitable for capturing large areas of nebulae, star clusters, and faint, fast-moving celestial objects.\u003c\/p\u003e\n\u003cp\u003eThe 0.8x reducer adopts a triplet design and supports a 44mm full-frame image circle. The overall weight is 0.48kg. The back focus from the M48 thread is a standard 55mm. The front thread is M84*1. At the camera end, it is equipped with M54*0.75 and M48*0.75 two sizes of adapters, which are convenient for connection. At the same time, it has a built-in M48*0.75 2-inch filter thread, which can be directly installed and used. The overall CNC machined, both end threaded metal caps prevent ash when not in use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(After attaching) 103APO Focal length: 560.32mm\u003c\/li\u003e\n\u003cli\u003e(After attaching) 103APO Focal ratio: f\/5.44\u003c\/li\u003e\n\u003cli\u003eLens Number: Triplet design\u003c\/li\u003e\n\u003cli\u003eBack Focus: 55mm (from the base of M48 male thread）\u003c\/li\u003e\n\u003cli\u003eWeight: 0.48kg\u003c\/li\u003e\n\u003cli\u003eRear-end thread type:\n\u003cul\u003e\n\u003cli\u003eM54×0.75\u003c\/li\u003e\n\u003cli\u003eM54×0.75-M48×0.75 (M48×0.75 filter thread inside)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Askar","offers":[{"title":"Default Title","offer_id":54479784542492,"sku":"ofk1787962816326","price":146.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/1023\/2604\/files\/askar-08x-full-frame-reducer-flattener-for-103apo-telescope_1.jpg?v=1787962823","url":"https:\/\/www.quietlaurel.shop\/products\/askar-08x-full-frame-reducer-flattener-for-103apo-telescope","provider":"My Store","version":"1.0","type":"link"}
