Application and Performance:

  • High transmittance and smallest bandwidth to maximize contrast
  • Steep spectral profile minimizes halos around bright stars
  • A single substrate to eliminate internal reflections   
  • Narrowband Objects: OIII Emission Nebulae, Planetary, Wolf Rayet Nebulae and Supernova Remnants
  • Use in light polluted areas and dark sites
  • Extends imaging time when the moon is up
  • Antlia narrowband Pro filters can be used down to F/3 systems with slight loss of signal
  • All Antlia Narrowband filters are edge blackened to eliminate internal reflections from stray light
  • Superior optical reliability reduces post image processing
  • This filter is not suited to deep sky objects that do not contain OIII emissions.
