Instead of buying extra flatteners, calculating the back focus for your flattener and then adding extensions or adapters to match the calculated distance, astrophotographers can simply equip the Askar 107PHQ with any imaging device, keep the target in focus, and then the whole optical system is ready for imaging. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/107PHQ_Highlight_Icons.png?v=1748981729\" alt=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe 107PHQ has an aperture of 107 mm,  a focal ratio of f\/7, and a focal length of 749mm.
