WitrynaSpecifications. Meade's Solar White-Light Herschel Wedge is proven to give a sharper, higher-contrast image than traditional metallized solar film or front-mounted glass solar filters, by eliminating reflections between the filter and front telescope lens. The result is a sharp, very high contrast view of Sun spots and solar surface granulation. WitrynaThe Altair Solar Wedge (Herschel Wedge) replaces the normal 2" mirror or prism diagonal at the rear of your refractor telescope. The Solar Wedge transmits a greatly …

The Continuum … WitrynaThe solar prism is suitable for refractor telescopes without built-in field flattener and is used instead of the zenith mirror. About 96% of the solar energy is dissipated by the Herschel-type prism, the remaining 4 percent are available for photography. The images are sharper and richer in contrast than with simple objective lens solar filters.
While the prism is constructed of special glass which absorbs UV and IR light, it cannot be used with a reflecting telescope design. This is because reflecting telescopes usually have a secondary mirror close to focus which may be damaged by the heat caused by IR light. This concentrated IR, in particular, … Zobacz więcej A Herschel wedge or Herschel prism is an optical prism used in solar observation to refract most of the light out of the optical path, allowing safe visual observation.
