OPTOLONG 2" L-Synergy Filter Dual 7nm Narrowband Filter OIII(500.7nm)&SII(672.4nm)
L-Synergy's advantage lies in its selective transmission of only the nebula emission lines OIII (500.7nm) and SII (672.4nm), while blocking all other light-polluting emission lines. This ensures that only the signals from oxygen and sulfur elements are captured during imaging, resulting in a darker sky background and significantly enhanced contrast and signal-to-noise ratio (SNR) between nebulae. Even in heavily light-polluted areas, this filter selectively transmits nebula emission lines while filtering out light pollution, ultimately eliminating its impact on astrophotography
