Optolong L2 Dual-Combo Filter Set
The Optolong L2 Dual-Combo Set includes two premium dual-narrowband filters, L-eXtreme and L-Synergy, designed for colour-camera astrophotography. Compatible with telescopes f/3.3 and slower, this set allows users to capture Hubble Palette deep-sky images without switching to a monochrome camera or buying a full three-filter SHO set. It provides professional-level narrowband imaging with minimal investment.
The L-eXtreme transmits OIII (500.7 nm) and Hα (656.3 nm), blocking unwanted light-pollution wavelengths to deliver bright nebula details with high contrast. Years of refinement optimise performance and reduce bright star halos.
The L-Synergy transmits OIII (500.7 nm) and SII (672.4 nm) with high efficiency while rejecting other wavelengths. It minimises light pollution effects and preserves nebula detail, producing clean data for processing.
The combination of these filters allows colour-camera users to achieve Hubble Palette imaging efficiently. It enhances nebula structure, improves contrast, and enables richer colour separation in light-polluted skies.
The filters are engineered to preserve the distinctive colours of nebulae while filtering out most light pollution. Their tuned transmission profiles ensure strong signal in the target emission lines and high signal-to-noise performance for detailed deep-sky images.
This set is ideal for astrophotographers using colour cameras who want professional-quality narrowband imaging with existing equipment.
