  14.   O-III Super-G Filter (9nm) - CMOS optimized

    O-III Super-G Filter (9nm) - CMOS optimized

    From: € 89.00 Price excl. German VAT tax (19%): € 74.79
    • O-III Super-G filter with 9 nm FWHM and a maximum transmission of 97%.
    • For visual and photographic observation of planetary nebulae and supernova remnants, even with small telescopes
    • Can be used as a "Super-G filter"  replacement for RGB photography. While regular G-filters suffer from bad seeing due to air turbulences, the narrow range of 9 nm passes less thermal noise, i.e. sharper images. Nevertheless, the transmission window is large enough not to be considered a pure narrowband filter.
    • CMOS-optimized coating technolog with much steeper slopes of the filter passband - for increased contrast, longer life and to avoid reflections.
