Broadband light pollution filter that selectively blocks mercury vapor, sodium, and LED sky glow while preserving natural starlight for cleaner images.
Description
The Optolong Clear Sky filter is a broadband light pollution filter designed to suppress artificial sky glow while transmitting the wavelengths most useful for astronomical observation and imaging. It selectively blocks common sources of light pollution including mercury vapor, sodium, and LED streetlight emissions, while passing the emission lines of nebulae and natural starlight. Suitable for both visual observing and DSLR/mirrorless camera astrophotography from light-polluted urban and suburban locations.
