The perfect mounting cell for eclipse photographers
AstroSolar film is the standard for white light solar filters. This mounting cell has two great advantages for eclipse photographers. The wide flange shades your camera avoiding overheating. The external 3 rubber bumper attachment is easy to remove and replace quickly without disturbing your aim. This is a great advantage for totality in a total solar eclipse. Highly recommended
• Highspeed Narrowband Filter, 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. 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
