DAS NBZ Filters are designed to enhance the contrast of Hα and OIII emission nebula, yet accommodate 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.

Features include:

  • Ideal flat-top bandpass
  • Excellent in-band transmission
  • Off-center bandpass accommodates off-axis rays for fast optics (up to F2)
  • Steep bandpass edges minimize internal reflections
  • No IR blocker required
  • Available in 52mm and 48mm sizes
  • 2.5mm thickness (parfocal with other IDAS LPS filters)
  • IDAS-proprietary IGAD/MBT/UFPquality
  • Made in Japan
