  • This is the updated version of the IDAS NBX filter, correcting for the "halo" effect present on the previous NBX model filters by reducing internal reflection.
  • Nothing else has changed between the previous and updated model.

Product Details

  • The IDAS Nebula Booster 52mm Filter is designed to enhance the contrast of Ha (Hydrogen Alpha) and OIII (Oxygen II) emission nebula while accommodating the filter spectral shift when used with modern fast optical systems. This dual-band filter is ideal for one-shot color cameras, as well as mono-color astronomical cameras.

    Proprietary IDAS Sophisticated Optics Technology

    Ion-Gun Assist Deposition (IGAD) coating technology is used by IDAS for these astronomical filters. This results in superior filters with robust coatings and long-term spectral stability, even with temperature and humidity extremes. This stability is especially important for bandpass curves with steep slopes (narrowband filters). This technology helps to virtually eliminate bandpass shifts from the +/-3 or 4nm typical of standard coating filters.

    The Multi Bandpass Technology (MBT) is used in conjunction with the IGAD hard-coating technology to further elevate IDAS filters. This technology allows IDAS to create very complicated filters for astronomical use.

    Ultra Fine Polish (UFP) Finishing really sets IDAS filters apart from the competition. They are polished twice as long as is typical for optical glass. In combination with the use of high-quality substrate glass, no scratches, bubbles, or other defects are visible even under microscopic inspection.

     

    Ha Bandpass

    OIII Bandpass

     

    This filter has ideal flat-top bandpass, as well as in-band transmission. The off-center bandpass accommodates off-axis rays for fast optics (up to f/2). The steep bandpass edges help to minimize internal reflections. It is able to fully block NIR up to 1200nm.

IDAS NBZ

This dual band filter works great on my RASA with my ZWO 2600 camera.
