Features: Baader 1.25-Inch F/2 Highspeed H-alpha / OIII / SII Filterset
- F/2 Highspeed Filterset consisting of 3 Filter: H-alpha, O III and S II
- Highspeed Narrowband Filter 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= Centre-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
- These filters allow to use fast optics really effectively with high contrast emission nebulae imaging Using these filters between f/1,8 and f/3,5 shows a dramatic improvement compared to any regular set of narrowband-filters
