This C90 Mak has excellent optics with razor sharp images over a wide field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaksutov-Cassegrain Optical Design\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe MAK is a catadioptric spotting scope, which means the optical design includes both a lens and a mirror. The light coming through a MAK passes through the corrector lens to the primary mirror and back to a spherical secondary mirror before it hits the eyepiece. Images are bright, sharp, and virtually free of chromatic aberration. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003eThe Maksutov-Cassegrain’s optical design offers several unique benefits. Instead of a secondary mirror, the MAK features a “secondary spot” of reflective coating applied directly to the inside of the corrector plate. Because of this, the spotting scope does not require frequent collimation. Also, the secondary spot is significantly smaller, giving the MAK its signature high-contrast views.\u003cbr\u003e\u003cbr\u003eOne important thing to note about Maksutov-Cassegrain spotting scope is that the larger, heavier Maksutov corrector plate takes longer to cool down and adjust to ambient air temperature.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdditional Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMulti Coated Optics\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaksutov-Cassegrain Optical Design\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eCompact and Portable Design\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eErect Image System for Terrestrial and Astronomical Use\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eBuilt-in T-Adapter threads for Ease of Adapting SLR Cameras\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eComes with 32 mm Eyepiece, 45° Erect Image Diagonal and 8x21 Erect Image\u003c\/li\u003e\n\u003cli\u003eFinderscope\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eBackpack Made of Nylon\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eLimited Lifetime Warranty\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"box-sizing: inherit;
