Baader F/2 Highspeed-Filterset 2-Inch H-alpha / OIII / SII

Features: Baader F/2 Highspeed-Filterset 2-Inch H-alpha / OIII / SII

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
For the first time 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
