With this prism, you will enjoy very comfortable observations, without impossible postures, at 90 or 45º (depending on the version). It is very useful for orienting yourself with a lunar or celestial chart!\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSummary of advantages:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNatural 90º orientation, for observing through the telescope as if looking directly through a lens telescope\u003c\/li\u003e\n\u003cli\u003eHelps with orientation on lunar and celestial charts\u003c\/li\u003e\n\u003cli\u003e29 mm optical path, for observation without shadows even at long focal lengths and wide fields of view\u003c\/li\u003e\n\u003cli\u003e120 mm optical travel\u003c\/li\u003e\n\u003cli\u003eBetter image quality than with an Amici prism\u003c\/li\u003e\n\u003cli\u003eExact 90º optical angle, regardless of the angle of incidence\u003c\/li\u003e\n\u003cli\u003eClamping screw and 1.25\" filter thread\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eOrientation for navigating lunar and celestial charts\u003c\/b\u003e\u003cbr\u003eWhen orienting yourself in the sky, it's very easy to get disoriented. Especially when working with lunar charts and some celestial charts. To identify a specific lunar crater, you first have to flip the image obtained through a star diagonal, which is upright, but laterally inverted. And that's not easy at all! However, with the pentaprism, you save yourself this complicated task. To get the correct orientation, simply rotate the celestial chart 180º.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eUltra-clear images with rich contrast\u003c\/b\u003e\u003cbr\u003eBK-7 glass, dielectric and with multi-coated surfaces: these three technical characteristics are the reason why the images are so bright and clear with such high luminosity. But furthermore, the image quality is much superior to that offered by a good Amici prism. And it's all due to the exclusive design, which lacks those edges present in other prisms that contribute to worsening the image. This pentaprism is an optical work of art carved from a single piece.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNo vignetting for views without darkened edges\u003c\/b\u003e\u003cbr\u003eYou can use long focal length or wide field of view eyepieces. A great advantage of the 29 mm optical path is that your clear view of the sky will not be limited.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAnodized housing with anti-reflective darkening\u003c\/b\u003e\u003cbr\u003eInside, the prism is darkened and opaque. This maintains good contrast for more enjoyable observation.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePentaprism: a professional accessory for astronomical observations\u003c\/b\u003e\u003cbr\u003eWhen it comes to correctly orienting yourself on a celestial chart, the pentaprism is a real blessing, because it maintains the normal image orientation of refractor telescopes. This accessory is a five-sided prism equipped with two highly reflective surfaces. The incoming light always finds its way at a right angle, whether it enters directly or diagonally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581588463959,"sku":"57293","price":139.67,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/57293_3.jpg?v=1779016145","url":"https:\/\/astrotelescopios.com\/en-efta\/products\/prisma-pro-penta-prisma-de-45%c2%ba-1-25","provider":"Astro Telescopios","version":"1.0","type":"link"}
