The closed \u003cstrong\u003eMaksut-Cassegrain\u003c\/strong\u003e optical system ensures clearer image contrast across the entire field. It is ideal for monitoring the planets of the Sun system and the Moon, as well as for observing bright nebulae, galaxies and bright stars, new stars and comets. The telescope is equipped with an adapter for a smartphone, a solar filter and equatorial mountings, which can also be used for video monitoring of planets. Maksutov-Cassegrain catadioptric telescopes loom at low, uninterrupted levels. First of all, the focal length is large with small dimensions, which allows you to use clear, long-focus eyepieces and capture a clear image. In addition, the closed design interferes with the influence of wind flows in the optical tube, which significantly reduces the brightness of the image. The head mirror of the telescope tube is made of special \u003cstrong\u003ePyrex\u003c\/strong\u003e material with a low coefficient of thermal expansion, which reduces optical performance and increases the service life of the device. Meniscus made from optical glass BK-7. All optical surfaces are highly spherical, increasing the efficiency of light transmission. The equatorial installation of the telescope with the mechanisms of thin arms makes it easy to take care of the additional movement of the objects along the horizon. The “dovetail” fastening is easier for installation with complete installations and allows the pipe to be installed on larger and wider equatorial installations. Due to its compact size, the telescope is also handy for keeping a close eye on places (for example, on a balcony or loggia) and takes up minimal space while saving on transportation. In addition to the built-in diagonal mirror, this model can be successfully used for landscape monitoring and digital photography (photography using an additional camera). \u003c\/p\u003e\n\u003cp\u003eThe flagship line of Messier telescopes from the German Bresser telescope is distinguished by high folding capacity, precision of the supply of optical elements and high-quality components materials. There are no compromises between price and price. All components, parts, and mirrors of the telescope are made with precision precision, which provides the best optical and operational characteristics in its class. Bresser telescopes are highly rated by experienced astronomy enthusiasts.\u003c\/p\u003e | Manufacturer code: 926263\n Parameters:\n Color: White\n Warranty: 12 months \nBrand registration country: Germany\n Country of origin for product: China\n Vaga: Pipe, kg: 1.8 Tripod, kg: 1.5 Installation, kg: 1.7 Telescope (with accessories), kg: 5.9\n Equipment: Pipe: aluminum\u003cbr\u003e\n Tripod: aluminum with object table for accessories\u003cbr\u003e\n Mounting: equatorial EQ-3\u003cbr\u003e\n Eyepieces: SPL 26 mm (1.25'')\u003cbr\u003e\n Vidoshukach: spot LED\u003cbr\u003e\n Adapter for smartphone (tablet) camera\u003cbr\u003e\n Sunny filter\n Opening: 1:14\n Video camera: LED with pinpoint guidance\n Limit value: 11.9\n Montuvannya: Ekvatorialne\n Computer guidance: No\n Optical design: Maksutov-Cassegrain \nEAN code: 4007922028255\n Package dimensions: 37 x 21 x 73 cm\n Dimensions: Telescope dimensions (length x width x height), mm: 900 x 900 x 1600\u003cbr\u003e\n Dimensions of the optical tube (diameter x length), mm: 105 x 350\u003cbr\u003e\n Height of tripod with mounting (min-max), mm: 680-1200\n Package weight: 8.6 kg\n Separate building time: 1.56 seconds\n Eyepiece mounting diameter: 31.75 mm\n Magnification: 48x (with different eyepieces included in the kit)\n Maximum color increase, times: 180\n Item: 926263\n Brand: Bresser\n","brand":"Bresser","offers":[{"title":"Default Title","offer_id":41290425335985,"sku":"sva_2491","price":27572.16,"currency_code":"UAH","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0538\/8517\/3937\/files\/teleskop-bresser-messier-mc-90-1250-eq3-38617124522255__325d220211_b6ee4577-792e-446c-a922-2b29fa4f1783.jpg?v=1754262360","url":"https:\/\/usefulrare.com\/products\/2491","provider":"Dostavka","version":"1.0","type":"link"}
