Three-Band Light Pollution Filter – Optimized for Modern Color CMOS Cameras

Designed for astrophotographers and astronomy enthusiasts working under light-polluted skies, this three-band pass filter offers a powerful yet cost-effective alternative to expensive monochrome cameras and filter wheels.

It precisely isolates the main emission lines – H-alpha, OIII, SII, and NII – with peak transmission rates above 92% and up to 97% maximum, delivering exceptional detail not only in emission nebulae but also in galaxies, star clusters, and globular clusters, even in urban environments.

Perfectly compatible with the latest generation color CMOS sensors, this filter is ideal for optical systems with focal ratios as fast as f/2.0. Its advanced optical quality ensures high-contrast, sharp images while significantly reducing post-processing time.

  • Recommended for: Light pollution reduction, enhanced contrast for emission nebulae, saving post-processing time
  • Ideal use with: Color and monochrome CMOS cameras
  • Compatible systems: Focal ratios down to f/2.0

Technical Specifications

  • H-alpha transmission: >92% @ 656.3 nm
  • [S II] transmission: >92% @ 671.6 / 672.4 nm
  • [O III] transmission: >92% @ 495.9 / 500.7 nm
  • [N II] transmission: >92% @ 654.8 / 658.3 nm
  • Blocking range: ≥OD4 from 300 to 1100 nm
  • Filter thickness: 2 mm ± 0.05 mm
  • Supported focal ratio: down to f/2.0
