Product information "NATIONAL GEOGRAPHIC 10x50 Porro Binoculars"
These elegant Porro-prism binoculars have excellent optical characteristics. The green fully coated optics guarantee a decisively higher light transmission through the glass, thus increasing color fidelity and contrast. Diopter compensation is standard with these models. This makes these binoculars suitable for beginner birders or nature observers. Even on windy days, due to the 10-fold magnification, a stable image is provided. The 50 mm objective lenses gather enough brightness for observation even in twilight conditions. A carrying pouch and neck strap are included. For longer observations, a tripod-adapter thread is integrated.

EXPLORE SCIENTIFIC 1.25" UHC Nebula Filter
€58.00*
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC UHC filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The Explore Scientific UHC nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the Owl-nebula M97, the Veil-nebula NGC6992 or even the bright Dumbell-nebula M27 are not clearly visible. By using this filter you can see the nebulae and their structures without problems. A must for every visual observer.
The EXPLORE SCIENTIFIC nebula filters come with a individual test certificate - your guarantee to receive a premium filter.FEATURESenables the observation of emission nebulaeblocks almost the entire artificial lightonly the two emission lines of hydrogen and oxygen passes the filterWHAT'S INCLUDED1x 1.25" UHC nebula filter
