Explore Scientific 82° AR 11 mm 1,25" szemlencse

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the “averted vision” technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.MárkaExplore ScientificSzavatosság2 годаEAN4007922199726A csomag méretei (HxSzxM):15x11x8 cmSzállítási súly0.434 kgFókusztávolság, mm11Látómező, °82VízállóyesOldalsó szélek sötétítéseyesParfokálisyesArgon-tisztítottyesVédősapkák a készletbenyesSzemtávolság, mm15.6Látómezőhatár átmérője, mm15.9Típusultra széles látószögOptikai rendszer7 alkotóelem 4 csoportbanSzemlencsetubus átmérője, hüvelyk1,25Lencse bevonatafully multi-coated EMDSzemkagylógumi, összecsukható
