SHO 7nm Prime Kit - 36mm (unmounted)

Antlia 7nm Prime filter kit - H-alpha, OIII, SII

Take your astrophotography to a new level with the Antlia 7nm Prime kit. This pack includes H-alpha, OIII and SII filters optimized to capture the entire SHO spectrum with great precision, even with high-speed lenses up to f/2.

Kit contents

• Antlia H-alpha 7nm Prime filter (656.3nm)
• Antlia OIII 7nm Prime filter (500.7nm)
• Antlia SII 7nm Prime filter (672.4nm)

Why choose the Antlia 7nm Prime kit?

• High transmission (>90%) to capture maximum H-alpha, OIII and SII signals.
• Optimized bandwidth at 7nm for an excellent balance between strong signal and spectral selectivity.
• Compatibility with high-speed optics up to f/2, ideal for ultra-bright setups.
• OD4 out-of-band suppression for exceptional contrast and a darker background sky.
• One-piece design glueless, with blackened edges, reducing internal reflections and stellar halos.
• Color fidelity in Hubble Palette (SHO) compositions for images that are both scientific and artistic.

Ideal applications

• SHO astrophotography (Hubble palette: SII - Ha - OIII)
• Photographing emission and planetary nebulae
• Observation of Wolf-Rayet regions and supernova remnants
• Use on polluted urban sites or under deep skies
• Photographic projects even with the presence of the Moon
