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 shooting large areas of nebulae, star clusters, and faint, fast-moving celestial objects.\u003cbr\u003e\u003cbr\u003e- The 0.8x reducer adopts a triplet design and supports a 44mm full-frame image circle. The overall weight is 0.75kg. The back focus from the M48 thread is a standard 55mm. The front thread is M84x1. we have equipped three sizes of adapter, M68x1, M54x0.75, and M48x0.75 for easy subsequent connection and use. At the same time, it has a built-in M48x0.75 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecification:\u003c\/b\u003e\u003cbr\u003e- (After attaching) 120APO Focal length: 672mm\u003cbr\u003e- (After attaching) 120APO Focal ratio: f\/5.6\u003cbr\u003e- Lens number: Triplet design\u003cbr\u003e- Back focus: 55mm (from the base of M48 male thread)\u003cbr\u003e- Weight: 0.75kg\u003cbr\u003e- Rear-end thread type: M68x1; M54x0.75; M54x0.75-M48x0.75 (M48x0.75 filter thread inside)\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Reducer\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/99008\/99010-01.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/99008\/99010-02.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/99008\/99010-03.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products, Audio Amplifer and Decoders","offers":[{"title":"Default Title","offer_id":41028704370737,"sku":"99010","price":226.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1758936236-1.jpg?v=1780321210","url":"https:\/\/www.thanksbuyer.com\/ja\/products\/askar-0-8x-triplet-design-full-frame-reducer-professional-astronomical-accessory-for-120apo-telescope","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
