The 0.8X focal reducer is made of high quality metal, with a beautiful design, and it's simple to use. The focal ratio is reduced from the original f\/5.5 to f\/4.5, and combined with your existing 61EDPH APO, produces sharp images and bright peripheral stars. It's an indispensable accessory for astro-imaging enthusiasts.\u003c\/p\u003e\n\u003cp\u003eA triplet air-spaced design, including a 360° rotator and M48 thread. Fully considering the needs of pro users, the back focus including rotator is the standard 55 mm. The 61EDPH reducer is equipped with a 2.3\" tube, one end of which adopts a M63×1 thread and connects to the pinion focuser of the primary mirror. The other end has an M48×0.75 thread, and the focal plane is 55mm from the end interface. If you need to expand the back focus, it can measure up to 99mm by removing the end interface and then using your own accessories to achieve the back focus you require.\u003c\/p\u003e\n\u003cp\u003eIf you are using the SharpStar 61EDPH APO Refractor telescope for visual observations and are now ready to embark upon astro-imaging work, this is an important accessory to add to your gear box.\u003c\/p\u003e","brand":"SharpStar","offers":[{"title":"Default Title","offer_id":31955032047729,"sku":"SHA-61EDPHII+FR","price":584.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/SharpStar_61EDPHII_with_Reducer.jpg?v=1776458991","url":"https:\/\/khanscope.com\/en-fr\/products\/sharpstar-61edphii-f-5-5-triplet-apo-telescope-with-0-8x-full-frame-focal-reducer-61edphii-fr","provider":"Khan Scope Centre","version":"1.0","type":"link"}
