Product information

  • f/2 Highspeed filterset consisting of 3 filters: H-alpha, O III and S II. Highspeed Narrowband Filters are designed especially for the delicate requirements of extremely fast astrograph optics, in particular Hyperstar and RASA
  • conventional narrowband filters cause a heavy loss in transmission due to the strong CWL-shift. In extreme cases the CWL even does shift out of the FWHM (CWL= Center-wavelength / FWHM= full width half maximum). Therefore these filters have a CWL-preshift which matches f/2 to f/3 perfectly
  • the FWHM is optimized. In spite of the typical line broadening with such fast optical trains they are able to deliver maximum contrast
  • for the first time use fast optics really effectively for high contrast emission nebulae imaging. Triple S/N-ratio when compared to common narrowband filters at f/2.
  • using these filters between f/1,8 and f/3,5 shows a dramatic improvement compared to any regular set of narrowband-filters
