By reducing the focal ratio from f\/7 to f\/5.4, it increases imaging speed, allowing significantly shorter exposure times while maintaining image brightness and detail. The focal length is reduced to 810mm, providing a wider field of view ideal for capturing larger deep-sky objects. With a corrected 36mm image circle, it supports APS-C sensor formats without edge distortion. The reducer offers a flexible 90mm back focus, or 55mm when using the included spacer and M48 adapter, and features integrated 2\" filter threads for convenient filter attachment. \u003c\/p\u003e\u003cbr\u003e","brand":"SKY-WATCHER","offers":[{"title":"RYDA","offer_id":40428619006153,"sku":"10074180","price":654.41,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0024\/9803\/5810\/files\/30b5dbc38ca44601988a90a6c2102a13.jpg?v=1782462444","url":"https:\/\/www.jbhifi.com.au\/products\/sky-watcher-77x-reducer-flattener-for-150ed","provider":"JB Hi-Fi","version":"1.0","type":"link"}
