SVBONY SV260 2″ Multi-Bandpass Broadband Filter
The SVBONY SV260 is a 2″ multi-bandpass broadband light pollution filter designed for deep-sky astrophotography. Using a five-bandpass transmission design, it helps suppress common sources of artificial light pollution while maintaining strong signal throughput for galaxies, reflection nebulae, and wide starfield imaging.
Five-Bandpass Broadband Design
The SV260 employs a five-bandpass broadband transmission profile, allowing multiple astrophotographic wavelengths to pass while selectively reducing the impact of common light pollution sources. This makes it suitable for broadband targets where colour balance and starfield integrity are important.
High Transmission & OD4 Cut-Off
With peak transmission exceeding 90% and an OD4 cut-off depth, the filter is designed to block unwanted wavelengths efficiently while preserving image brightness. This combination supports improved contrast without excessive signal loss.
Wide Wavelength Coverage
Operating across an approximate wavelength range of 300–1000 nm, the SV260 provides broad spectral coverage suitable for DSLR, mirrorless, and dedicated astronomy cameras. This wide range allows flexibility when imaging diverse deep-sky targets.
Designed for Light-Polluted Skies
The SV260 is intended for use in moderate to heavy light pollution environments, including urban and suburban locations. It is particularly effective for wide-field starfield imaging and broadband deep-sky photography under artificial sky glow.
Imaging Examples & Compatibility
Below are example results and typical usage configurations. The filter is compatible with standard 2″ filter threads and can be used with telescopes, camera adapters, and imaging trains that accept 2″ accessories.
