With this optical tube, you won't have to ask yourself that question, because it serves both purposes. This series draws on the elements that turn a simple optical tube into a powerful astronomical instrument.\u003c\/p\u003e\n\u003cp\u003eWith it, you can enjoy well-defined lunar craters, richly detailed planets, and deep-sky objects that will appear brighter than with a standard telescope. With the Omegon Pro Newton, you'll hit the mark: we offer you an ideal combination of finish and quality so that everything works perfectly on your journeys through the Universe.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAdvantages at a glance:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOptical tube with excellent finish: for years and years of observations\u003c\/li\u003e\n\u003cli\u003eBK-7 primary mirror with 94% reflectivity: clearer images than with a normal mirror for sublime contrast\u003c\/li\u003e\n\u003cli\u003e2\" Crayford focuser: smooth focusing to help you find the perfect sharp point\u003c\/li\u003e\n\u003cli\u003eMore backfocus: attach your SLR camera or any other\u003c\/li\u003e\n\u003cli\u003eEasy to mount: thanks to the dovetail solution, the tube is compatible with all mounts with Synta\/Vixen\/Skywatcher\/Celestron systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eHigh-quality metal tube with excellent finish\u003c\/b\u003e\u003cbr\u003eThe tube of this telescope is perfect for starting such a fascinating hobby. It replaces plastic with carefully finished metal, an essential condition in the world of telescopes to continue observing the night sky for many years.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eBK7 primary mirror\u003c\/b\u003e\u003cbr\u003eThe heart of the telescope is its BK7 glass primary mirror. Compared to \"conventional\" glass, this offers a more stable shape during the cooling phase, which means that image quality improves even when the tube has not fully acclimatized to ambient temperature.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eImproved coating: 94% reflectivity for brighter images\u003c\/b\u003e\u003cbr\u003eWhen you delve into the depths of the Universe through the telescope, you see objects that you would never be able to see with the naked eye. To achieve this, there are two vital elements: the aperture and the primary mirror, which, in this telescope, has a reflectivity rate of 94%. This allows you to enjoy extra clear images and first-rate contrast to explore the sky and see even the faintest deep-sky objects.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e2\" Crayford focuser for ideal sharpness\u003c\/b\u003e\u003cbr\u003eThe 2\" SingleSpeed Crayford focuser allows you to focus with any eyepiece of your preference. And all thanks to its ball bearing, which ensures smooth and precise gliding to find the exact focal point.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAstrophotography: compatible with your SLR camera\u003c\/b\u003e\u003cbr\u003eIn theory, to take astrophotos, all you have to do is attach the camera and press the shutter, but sometimes telescopes don't make it that easy. However, this optic offers enough backfocus to make it that simple. What does this mean? It means you can achieve perfect focus to take dream photos even with a large DSLR camera.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSimplified mounting: compatible with most mounts\u003c\/b\u003e\u003cbr\u003eThe 33.5 cm long Vixen-style dovetail bar serves as an interface for practically any acceptable mount. It is the definitive standard for most high-quality mounts. And best of all, the tube can be mounted and balanced in a matter of seconds.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eThin vane spider and maximum contrast\u003c\/b\u003e\u003cbr\u003eAny self-respecting astronomer knows that the spider is not the eight-legged insect that spins its web in corners, but the piece that holds the secondary mirror. In this case, its vanes are only a few millimeters thick. The result is excellent contrast.\u003c\/p\u003e\n\u003cp\u003eOur assessment: overall, a perfect tube for beginners or those looking to upgrade.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eTube fan for faster observation\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eObserve without waiting! When preparing a tube for observation, the primary mirror must cool down. The larger the mirror, the more patience you will need. But the integrated active ventilation of the primary mirror ensures faster cooling. For images of convincing quality.\u003c\/p\u003e\n\u003cp\u003eScope of delivery of the Omegon Pro N 254\/1250 OTA Newtonian:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e254\/1250 mm optical tube\u003c\/li\u003e\n\u003cli\u003e2\" Crayford focuser with 1:10 reduction\u003c\/li\u003e\n\u003cli\u003e2\" to 1.25\" reducer adapter\u003c\/li\u003e\n\u003cli\u003e35mm to 2\" extension tube\u003c\/li\u003e\n\u003cli\u003e8x50 finder scope with bracket\u003c\/li\u003e\n\u003cli\u003eBattery compartment for the tube fan\u003c\/li\u003e\n\u003cli\u003e2 tube rings\u003c\/li\u003e\n\u003cli\u003eDovetail bar.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581585482071,"sku":"63077","price":495.04,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/63077_1.jpg?v=1779016044","url":"https:\/\/astrotelescopios.com\/en-efta\/products\/telescopio-pronewton-n-254-1250-ota","provider":"Astro Telescopios","version":"1.0","type":"link"}
