Solar Telescope Solarview 50 mm 0.7 A

" are real solar H-alpha telescopes with bandwidth from 0.7 A specifically designed and engineered in the optics for solar observation . They are available in two versions 50mm f / 8 and 60mm f / 8, always with the free opening unobstructed . The lens is specifically designed to provide the best results in the line of 'H-alpha. They are equipped with 31.8mm focuser micrometer scale by reference millimeter perfect for photography and photographic tripod mount. Weight 1.5Kg and 2.2Kg, length 36 and 48cm. Possibility to mount on various mounts. Seeker Solsearcher supplied as standard. Key benefits and features of using a Solarscope or the Solarview:

• Absence of obstruction, of all openings from 50 and 60 mm This results in a greater increase in contrast and definition than H-alpha telescopes clogged. < li> tilting mechanism for precise commissioning band dell'etalon and doppler studies on bumps. The tilting in Solarscope acts internally, so the filter is always perpendicular to the optical axis, thus avoiding ghost images.
• The blocking filter comes standard with all Solarview has an aperture of 20 mm. This means not having any limitation or photographic observation.
• Etalon Fabry-Perot with bandwidth of
• Thermally stable: all the H-alpha telescopes have a ' very high thermal stability () so as to allow observations continued throughout the day without displacements of bandwidth. The Solarscope has succeeded in designing an H-alpha filter where you get a perfect thermal stability and centering of constant bandwidth, WITHOUT the aid of an obstruction centrale.Come say they represent, in our view, an evolution from precendenti H-alpha filter! All this has been confirmed by several tests conducted by magazines that have confirmed the perfect thermal stability, in any situation and during a full day under the sun.
• All optical surfaces of the filter are worked better than 1/100 lambda and are treated with anti-reflective dielectric process high efficiency all internal metal surfaces are dulled 100% dielectric process to avoid ghosting.
• Construction flawless made entirely of aluminum alloy machined or milled from solid with tight tolerances. Black anodized finish and satin. Closing screws in steel with final nylon to avoid scratching the eyepieces or other accessories.
• Safe: the special filters eliminate totally the ultraviolet, infrared, and much of the blinding brightness of the sun. And 'making it ideal for any use is professional and popular. The solar brightness is automatically adjusted to a value not tiring for the eyes.
• The entire production is centered on quality: a Zygo interferometer is used to monitor the optical quality throughout the production process the "" test-camera "" was built on a foundation separate than the production area in order to test the tools in total absence of vibrations.
• All filters and the telescope Solarview are individually tested instrumentally and also directly on the Sun before being delivered to the customer in order to guarantee the best optical performance .
