Filters L-Synergy 2"

‌L-Synergy‌ is a dual 7nm narrowband filter compatible with DSLR cameras, color CMOS sensors, and CCD cameras, supporting telescope systems with F-ratio of F3.3 or above (slower system).

Its key advantage lies in enabling astrophotography amateurs to capture exceptionally detailed emission nebulae even in light-polluted environments. After years of technical refinement, it has been optimized to minimize bright star halos while isolating all emission lines except SII and OIII, achieving maximum effective transmission.
