Capture the cosmos in stunning "Hubble Palette" detail. This professional ZWO 36mm unmounted filter set includes H-Alpha, OIII, and SII narrowband filters with a sharp 7nm bandpass. Optimized for deep-sky astrophotography, these filters feature fine-optical polishing to 1/4 wave accuracy and multi-layer AR coatings to eliminate reflections and reveal the hidden structures of nebulae.

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 minimal loss of signal
• All Antlia unmounted narrowband filters are edge blackened to eliminate internal reflections from stray light
• Superior optical reliability reduces post image processing
• This filter is only effective for deep sky objects that contain OIII emissions
