  • 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 48mm 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.

Great dual narrowband filter for fast telescopes and OSC cameras

The IDAS NBZ is awesome and parfocal with my IDAS D2 and D3 light pollution filters. I am using this filter on a f/4.7 telescope and it is on band and really pulls in the Ha and O3 signal.

Edge HD 8 Hyperstar V2 performance is sweet!

I've only had it out one night so far but was very impressed by it's performance! ZWO 294 color camera produced amazing results. 45 mins on the Horsehead and 90 mins on the Rosette. Great filter, as billed, maybe better and works great at F 2.1 IDAS NBZ 48mm

Love this.

This filter has changed my Dso imaging from meh to great. So glad I got it. Very excited for the coming year of imaging. I use this with Hyperstar. No halos.

Best filter yet

This filter is Great and I highly recommend it. I just cannot tell u how much better my images are, and you will see the same. I am in Bortle 9 skies, yet I get images where it appears I am in Bortle 2-3 skies, truly amazing! The cost is very reasonable compared to having an hour or 2 drive, to get to dark skies, now I can image from home!!!! Thanks OPT and IDAS!!!!!

One of the best

This filter is one of the better performing ones i have tested. The NBZ filter is good for F7 and faster scopes. I have only tested this so far with my c11 edge hd and hyperstar v4 during a full moon. The filter did a great job not only cutting the light pollution but also the glare from the moon. Its not as good as a narrowband Ha filter but the data is quite useable. Very impressed. Im also impressed that bright stars have very little halo. The antireflective properties are pretty amazing.

Amazing filter for RASA

the NBZ and RASA 8 are a great combination. I was able to shoot the Veil Nebula and M27 (Dumbbell) under a full moon and get pretty decent results. Haven't tried it yet under dark skies, but I am really looking forward to seeing what it can do. This filter works great with fast scopes like the RASA (f2) and doesn't seem to suffer the same loss of signal that the Optolong L-Extreme does.
