With a 0.85x reduction factor, it shortens the focal ratio from f\/5.8 to f\/4.93 and reduces the focal length from 420mm to 357mm, allowing for shorter exposure times and a wider field of view. Field curvature, which can distort stars at the edges, is corrected, producing sharp, well-defined stars across the image. The reducer\/flattener easily attaches to the Evostar focuser, and its M48 male thread ensures compatibility with most camera adapters and T-rings, making it versatile for imaging setups. \u003c\/p\u003e\u003cbr\u003e","brand":"SKY-WATCHER","offers":[{"title":"RYDA","offer_id":40427790467273,"sku":"10060431","price":559.41,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0024\/9803\/5810\/files\/8575ab4302664a8e852933adb828b83a.jpg?v=1781261108","url":"https:\/\/www.jbhifi.com.au\/products\/sky-watcher-reducer-flattener-for-72ed","provider":"JB Hi-Fi","version":"1.0","type":"link"}
