Antlia 3NM SHO Narrowband Imaging Filter Set – 2-Inch Mounted (SII, Ha, OIII)

Description

• 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.
