After connecting with the Askar 103APO, it still maintained a focal length of 6.8. The flattener corrects field curvature and coma, resulting in flatter field edges and finer star points.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe 1.0x flattener adopts a triplet design and supports a 44mm full-frame image circle. The overall weight is 0.58kg. The back focus from the M48 thread is a standard 55mm. The front thread is M84*1. At the camera end, it is equipped with M54*0.75 and M48*0.75 two sizes of adapters, which are convenient for connection. At the same time, it has a built-in M48*0.75 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.\u003c\/span\u003e\u003c\/p\u003e","brand":"Askar","offers":[{"title":"Default Title","offer_id":54035100794991,"sku":null,"price":300.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/IMG-6936.webp?v=1786728372","url":"https:\/\/ontariotelescope.com\/products\/askar-1x-full-frame-flattener-for-103apo","provider":"Ontario Telescope and Accessories","version":"1.0","type":"link"}
