The 86MA is the inaugural model in this lineup. While maintaining the high standards of SKY ROVER telescope, the 86MA features a native flat field design, integrating a triplet objective lens with a crescent-shaped field flattener through an optimized, unified optical system. The front lens group utilizes dual ED glass elements to enhance performance. Upholding SKY ROVER's stringent optical requirements, the MA series offers superior chromatic aberration control compared to similar products on the market, delivering finer image quality without compromising resolution. It supports full-frame imaging directly at prime focus—no need to calculate back focus—and also performs excellently with the addition of a 0.8x reducer. Compared with other imaging scopes in the SKY ROVER lineup, the MA series is compatible with standard astronomical accessories such as diagonals and eyepieces. It also supports advanced setups like binoviewers when used with an extender.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThanks to its F\/7 focal ratio, the MA series is forgiving in terms of focus precision, making it easier to achieve sharp, high-quality images. When used with the reducer\/flattener, the image plane remains sufficiently flat in most cases. For added precision, we've thoughtfully designed a compact flange ring that allows for fine-tuning focus when using the reducer, ensuring excellent imaging results.\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0661\/3873\/4829\/files\/1_68467e9c-5e6c-4e1b-a92c-ad0af4c155aa.png?v=1753535403\" style=\"float: none;\"\u003e\u003cmeta charset=\"utf-8\"\u003e\n\u003ch2 style=\"text-align: center;\" align=\"start\"\u003eProduct Details\u003cmeta charset=\"utf-8\"\u003e\n\u003c\/h2\u003e\n\u003ch3 align=\"center\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eOptical Construction\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eAir-spaced quadruplet (four elements) includes two ED glass lenses\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0661\/3873\/4829\/files\/2_0534244e-8a1a-4d4c-9f51-6630d30a56fc.png?v=1753535801\" style=\"float: none;\"\u003e\u003cmeta charset=\"utf-8\"\u003e\n\u003ch3 align=\"center\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eA true all-in-one: for visual and astrophotography alike\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eThe 86MA multipurpose astrograph comes standard with a 2-inch adapter, as well as one focus extension tube, M54 adapter x1,  M48 adapter x1 for convenient astrophotography use.
