- Antlia 3nm SII 671.6 – 2\\” Mounted
- Antlia 3nm Ha 656.3nm – 2\\” Mounted
- Antlia 3nm OIII 500.7nm – 2\\” Mounted
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.
