The 66MA is the most compact model in this lineup at present. While maintaining the high standards of SKY ROVER telescope, the 66MA 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\/p\u003e\n\u003cp\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\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/D_c5e49031-1fed-4ab0-9444-3cb9bbe37acb.webp?v=1787940777\" alt=\"\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/D1.webp?v=1787940811\" alt=\"\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Capture_d_ecran_2026-08-28_141428_1024x1024.png?v=1787940894\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e66 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e462 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Ratio\u003c\/td\u003e\n\u003ctd\u003eF\/7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptics\u003c\/td\u003e\n\u003ctd\u003eAir-spaced quadruplet (four elements), includes two ED glass lenses, native flat field\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImage Circle\u003c\/td\u003e\n\u003ctd\u003e44 mm (Full Frame)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocuser\u003c\/td\u003e\n\u003ctd\u003e2.8\" R\u0026amp;P Dual Speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eM63x1 \/ M54x0.75 \/ M48x0.75 \/ 2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReducer\u003c\/td\u003e\n\u003ctd\u003e0.8× Full Frame Reducer (Optional)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccessories\u003c\/td\u003e\n\u003ctd\u003eTube ring, Vixen type plate, handle (compatible with Vixen type plate and Arca standard)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Length (Dew Shield Retracted)\u003c\/td\u003e\n\u003ctd\u003e34 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Length (Dew Shield Extended)\u003c\/td\u003e\n\u003ctd\u003e49 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDew Shield External Diameter\u003c\/td\u003e\n\u003ctd\u003e103 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eN.W.\u003c\/td\u003e\n\u003ctd\u003e3 kg (OTA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Weight\u003c\/td\u003e\n\u003ctd\u003e3.6 kg (rings \u0026amp; dovetail \u0026amp; handle)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacking\u003c\/td\u003e\n\u003ctd\u003eSoft bag, Transport carton\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eQuad OTA 66MA\u003c\/li\u003e\n\u003cli\u003eDovetail\u003c\/li\u003e\n\u003cli\u003e2'' to 1.25'' adapter\u003c\/li\u003e\n\u003cli\u003eHandle Bar and Tube Ring\u003c\/li\u003e\n\u003cli\u003eOptional 0.8x reducer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty \u0026amp; Manual\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/astronomyplus.com\/pages\/sky-rover-optics-warranty\" rel=\"noopener\" target=\"_blank\"\u003eSky Rover's 2 years warranty.\u003c\/a\u003e\u003c\/p\u003e","brand":"Sky Rover Optics","offers":[{"title":"Telescope Only","offer_id":52184148607205,"sku":"SRO-66MA","price":1175.0,"currency_code":"CAD","in_stock":true},{"title":"Telescope + 0.8x Reducer","offer_id":52184148639973,"sku":"SRO-66MA + 66MA0.8XR","price":1482.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/A_15e04943-4515-4cd6-ac17-f0e43dfb6062.png?v=1787941466","url":"https:\/\/astronomyplus.com\/products\/sky-rover-optics-66ma-multipurpose-quad-astrograph-66ma","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
