The Optolong L2 Dual Combo 2" combines L-Synergy and L-eXtreme dual-narrowband filters to enable Hubble-palette imaging with color cameras using just two filters instead of three. With premium 7nm dual-band filters, these filters provide incredible light pollution suppression and contrast, revealing nebulosity in crisp detail even in challenging light-polluted environments. Both filters feature a standard 2" threaded filter design and support telescope systems as fast as f/3.3 and slower. This innovative solution allows one-shot-color camera users to capture stunning SHO (SII, Ha, and OIII) images without switching to monochrome equipment or purchasing expensive full filter sets.
