Levy Comet Hunter OTA Telescope","description":"Highly corrected optics for wide-field observation and astrophotography. Developed in collaboration with the famous \"comet hunter\" David H. Levy. The Maksutov-Newton system has some advantages and disadvantages compared to the classic Newtonian design. Apart from the high price, the biggest disadvantage is the high price - the thick corrector lens in the front is the cause of this. The main advantage of the Maksutov-Newton compared to the classic Newtonian is the sharpness of the field of view. Classic Newtonian telescopes show a sharp star point only in the middle of the field of view - outside the optical axis they have a dominant aberration, called coma. This is inherent to the Newtonian design, and, therefore, valid for all Newtonian telescopes of all brands and not caused by manufacturing tolerances. Coma distorts the star image - the pinpoint star shows a tail, just like a small comet. This considerably decreases sharpness and contrast. The Maksutov-Newton shows a much sharper star image - for most applications, coma is not visible. This results in a high-contrast image across the entire field of view - for observations and for astrophotographers with DSLRs as well. This makes the Maksutov-Newton an ideal telescope for all uses, as it is capable of showing a strong field without the need for additional correctors.\u003cbr\u003e\u003cbr\u003eINCLUDES\u003cbr\u003e• Carbon fiber optical tube with 2\" focuser and 10:1 reduction\u003cbr\u003e• Carbon dew shield with dust cap\u003cbr\u003e• Tube rings with dovetail\u003cbr\u003e• Explore Scientific 52° 30mm Eyepiece\u003cbr\u003e• 8x50 finder scope, illuminated\u003cbr\u003e• Eyepiece barrel diameter: 2\" and 1.25\"\u003cbr\u003e• Tools\u003cbr\u003e• Instructions\u003cbr\u003e• Lunar map\u003cbr\u003e• Rotating star chart\u003cbr\u003e\u003cbr\u003eSpecifications: Total length including dew shield: 825mm Net weight including tube rings, handle, dew shield and finder scope: 7.9kg","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":52791584850263,"sku":"4852740","price":1458.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/4852740_M1_2019.jpg?v=1770989609","url":"https:\/\/astrotelescopios.com\/en-us\/products\/telescopio-explore-scientific-mn-152-david-h-levy-comet-hunter-ota","provider":"Astro Telescopios","version":"1.0","type":"link"}
