"These filters are very innovative because they have a unique and outstanding feature likely to get a lot more contrast and definition is the lack of central obstruction! Other sunscreens H-alpha, for example. Coronado , in fact suffer a significant obstruction in the opening of the filter (eg. Coronado 60: opening 60mm, 13.8mm obstruction that is 23%). There are those who still insist on saying, in order to justify their presence, that the obstruction effect of an optical system but now it is known worldwide that the opposite is true! But the absence of obstruction is not the only strength of Solarscope ... Key Benefits and Features:

  • Absence of obstruction, of all openings 50, 60 and 70 mm This results in a greater increase in contrast and definition than H-alpha filters clogged.
  • installed on any telescope it is a refractor, an SCT, a Maksutov, etc. (except newton)
  • tilting mechanism for precise commissioning band dell'etalon and studies Doppler 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 Solarscope has an aperture of 20 mm (in Coronado instead the standard filter has an opening from 5mm to 15mm, thus far smaller). This means you can work with focal too long and does not have unrestricted observation or photography. Solarscope in addition, the filter is mounted within a support by 50.8mm (on request also by 31.8mm), to use without limitations accessories from 50.8mm or 31.8mm (via the reducer supplied as standard). It follows that with Solarscope you can observe without bias or use its diagonals, turrets, binEyepiece, photo adapters from 50.8mm or any other accessory without limitation in diameter.
  • Etalon Fabry-Perot with bandwidth of < 0.7 A perfectly centered on 656.28 nm.
  • Thermally stable: all the H-alpha filters 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 that Solarscope represent, in our view, an evolution from H-alpha filters to precendenti! All this was confirmed by the various 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 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 telescopes 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 .
