This broadband filter to reduce light pollution is designed to improve the quality of your images in urban environments. With a transmission of 90% of the main emission lines of nebulae, such as Ha 656nm, OIII 496nm, 500nm, SII672nm and H-beta 486nm, this filter allows you to capture the subtle details of your celestial subjects.
Technical Characteristics
- Electron beam deposition technology with ionic assistance for exceptional durability and scratch resistance;
- Planetary rotation system for precision and homogeneity of layers, ensuring high transmission in the passband and significant optical density outside the band;
- Transmission of 0.1% out of band, specifically on the main emission lines of artificial light pollution, such as Na 589nm, Hg 435nm and 578nm;
Compatibility
This filter is compatible with color CCD cameras and unmodified DSLR. It can be used to improve image quality in urban environments.
