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.\u003cbr\u003e\u003cbr\u003e- The 0.84x reducer adopts a quadruplet design and supports an APS-C frame. The overall weight is 0.24kg. The back focus from the M48 thread is a standard 55mm. The front thread is M42x1 and the camera end thread is M48x0.75. At the same time, it has a built-in 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) 50EDPH Focal length: 230mm\u003cbr\u003e- (After attaching) 50EDPH Focal ratio: f\/4.6\u003cbr\u003e- Lens number: Quadruplet design\u003cbr\u003e- Back Focus: 55mm (from the base of M48 male thread)\u003cbr\u003e- Weight: 0.24kg\u003cbr\u003e- Rear-end thread type: 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\/99064\/99064-01.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/99064\/99064-02.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 1024px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/99064\/99064-03.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":41028712857649,"sku":"99064","price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1759215022-1.jpg?v=1780322085","url":"https:\/\/www.thanksbuyer.com\/es\/products\/sharpstar-f4-6-0-84x-reducer-high-quality-astronomical-accessory-dedicated-for-50edph-telescope","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
