The Altair Astro 3nm ULTRA filters are designed for astro imaging of nebulae with Mono CCD or CMOS cameras, blocking light pollution by cutting out the light pollution wavelengths. The filter blocks UV IR and has an anti-reflection AR coating to suppress halos around bright stars.

Narrowband H-Alpha, O-III and SII nebula filters from Altair for astrophotography with CMOS sensors for high contrast for telescopes with ~f/4.5

• optimized for CMOS sensors (Color and MONO)
• exact and narrow half-widths for optimal signal-to-noise ratio
• Identical filter thicknesses for homofocality
• Blackened edges
• The edge of the filter is sealed to prevent moisture penetration
• SiO2 coating for virtually unlimited lifetime
• Low-profile filter mount - height only 6 mm
• Certificate
