Optolong L-Synergy Dual Narrowband Filter
The Optolong L-Synergy filter is designed for astrophotographers using DSLR, color CMOS, or CCD cameras who want to achieve stunning narrowband results without switching to a monochrome system. By pairing traditional dual-narrowband (Ha & OIII) concepts with a unique “Ha & OIII + SII & OIII” approach, L-Synergy overcomes the usual limitations of colour cameras and makes Hubble-Palette–style imaging accessible to everyone.
With this filter, you can produce deep, high-contrast SHO-like images of emission nebulae using your existing colour camera—no additional SHO filters or monochrome upgrade required. It’s an affordable way to achieve professional-level results even under bright suburban skies.
Why Choose the L-Synergy Filter?
The L-Synergy is a dual 7 nm narrowband filter engineered for telescopes with an f/ratio of f/3.3 or slower. Years of optical refinement have produced a design that suppresses bright star halos while delivering extremely high transmission in the key emission bands.
-
Selective Narrowband Performance
Transmits only the OIII (500.7 nm) and SII (672.4 nm) nebula emission lines, rejecting unwanted wavelengths and light pollution. -
Exceptional Contrast and Signal-to-Noise
By isolating the oxygen and sulfur signals, the filter produces a darker background sky and dramatically improves contrast—especially valuable in heavily light-polluted environments. -
Light-Pollution Resistant
Filters out the vast majority of urban skyglow, allowing astrophotographers to capture clean, detailed nebula structure from almost any location.
Optical Design
L-Synergy is precision-engineered based on the spectral behaviour of emission nebulae and common light-pollution sources. Its carefully tuned passbands maintain consistently high transmission in both SII and OIII, ensuring accurate colour capture and high-quality data for processing.
The result: a powerful, easy-to-use narrowband solution that unlocks deep-sky imaging performance far beyond what typical colour cameras can achieve, giving more astrophotographers access to true SHO-style imaging.
