Filtre CLS 1,25" - SVBony

This wideband 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 Features

• Electron beam deposition technology with ionic assistance for exceptional durability and scratch resistance;
• Planetary rotation system for precision and uniformity of layers, ensuring high transmission in the bandwidth and significant optical density outside the band;
• Transmission of 0.1% outside the 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 DSLRs. It can be used to enhance the quality of your images in urban environments.
