EXPLORE SCIENTIFIC Mounting Bracket for 8x50 Finderscope black

Top viewfinder telescope with upright field, illumination, 90° view and pole viewfinder engraving - image sharpness and viewing behavior raise this viewfinder significantly above the level of the usual 8x50 viewfinder telescopes. The upright image field facilitates orientation. Multi-Coating on all surfaces. This polar finder is mainly intended for the observer with a transportable telescope. The 90° view facilitates operation, and with the help of the pole scale and the lighting, a telescope can be quickly and safely aligned to the celestial pole. The upright field of view makes the handling together with the high image sharpness a pleasant experience. The lighting is powered by two LR41 button cells.

The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope

​The EXPLORE SCIENTIFIC Hybrid Finder Scope Base is designed to accept all legacy EXPLORE SCIENTIFIC and BRESSER Messier finder scope brackets and mini dovetail-type (e.g. Vixen, Synta, and many other brands) finder scope brackets. The base has rugged all-metal parts with black-anodized base and chrome-plated metal screws. Safety stops prevent the finder scope from sliding through and from falling when attaching screws are loosened. There are threaded holes on the left and right sides of the EXPLORE SCIENTIFIC Hybrid Finder Scope Base for desired access to attaching screws. Includes bolts and screws for mounting the base to the optical tube assembly. Direct replacement for all EXPLORE SCIENTIFIC and BRESSER Messier telescopes, allowing the use of a wide range of other-brand finder scope options.FEATURESDirect replacement for all EXPLORE SCIENTIFIC and BRESSER Messier telescopesAccepts all legacy EXPLORE SCIENTIFIC and BRESSER Messier finder scope bracketsAccepts also mini dovetail-type fittings from e.g. Vixen, Synta and many other manufacturersRugged all-metal parts with black-anodized baseIntegrated safety stopsIncludes bolts and screws for mounting the baseBolt hole spacing 32.5mm for mounting on telescope tubeSuitable for screw diameter M4/M5 SCOPE OF DELIEVERYHybrid Finder Scope BaseBolts and screws for mounting

Thanks to the large aperture of 50 mm, the Vixen 7x50 finder scope immediately reveals many objects that are not visible in smaller viewfinders. This makes it easy to adjust the telescope to the target object. The red illumination of the finder scope can be dimmed to different levels.The eyepiece is detachable (31.7 mm diameter) so that a CMOS camera with 31.7 mm diameter (available separately) can be attached and used as an autoguider. The eyepiece unit with crosshairs is also removable in order to use 31.7 mm diameter eyepieces (sold separately) with different focal lengths. This allows the finder scope to be operated with various magnifications.The lens is designed to be compatible with CMOS cameras. The distance between the bottom of the 31.7 mm sleeve on the camera side and the sensor surface should be approximately 17 mm. However, the focus position may vary depending on the camera, so you should adjust the guiding camera for focus before use. The focus of the optics is adjusted by rotating the lens. First, the black lock ring on the main optics must be loosened. Then, the focus can be adjusted by turning the lens mount. Please also read the operating instructions for the viewfinder and the CMOS camera used.If the focus of the viewfinder has been adjusted, the focus position must be readjusted when using the eyepiece unit.FEATURESMagnification: 7xAperture: 50 mmLenses: coatedCrosshairs: illuminated in red, dimmableDimensions: 220 mm × Ø 58 mmWeight: 467 gSCOPE OF DELIVERY7x50 viewfinderEyepiece unit with illuminationCR2032 batteryInstruction manual

Experience the beauty of our Earth up close with the NATIONAL GEOGRAPHIC Explorer 8x42 Binoculars. The compact binoculars are ideal for nature lovers who don’t want to miss a thing while trekking, camping, or birdwatching. With the 8x magnification, you can explore your surroundings with impressive detail. Optimal clarity thanks to high-quality optics With a 42-mm objective lens diameter, the binoculars remain compact yet allow enough light to pass through to your eyes to provide clear and bright images. The full multi-coating increases light transmission and minimizes reflections. The result: a sharp image even in dimming daylight. The excellent BaK-4 glass (barium crown glass) also contributes to the fact that you can always enjoy exciting views with fine details through the binoculars. Comfortable viewing with or without glasses Glasses wearers will also benefit greatly from the Explorer 8x42. The binoculars are equipped with twist-up eyecups, making it easy to adjust the distance between the eyes and the eyepieces in no time. The diopter adjustment of +/- 3 ensures that differences in vision between both eyes are also compensated for. Robust design for any outdoor adventure These binoculars are built for durability. The grippy rubber armouring protects against shocks and provides a secure hold—even in rough terrain. Moreover, the binoculars are waterproof and nitrogen-filled to prevent the lenses from fogging up internally during temperature fluctuations. At the end of your expedition, you can safely store the binoculars in the supplied bag until your next exploration. Discover the wonders of nature from a whole new perspective with the NATIONAL GEOGRAPHIC Explorer 8x42 Binoculars.
