Optolong L-eNhance Light Pollution Dual-Bandpass Imaging Clip Filter for Canon EOS APS-C

The Optolong L-eNhance Clip Filter is a dual-bandpass light pollution filter optimized for Canon EOS APS-C DSLR and mirrorless cameras. Designed specifically for RGB astrophotography in urban skies, it isolates critical emission lines—H-Alpha, H-Beta, and OIII—while blocking out broadband light pollution from artificial and natural sources.

With >90% transmission at key nebula wavelengths and strong suppression from 300nm to 1000nm elsewhere, the L-eNhance enables vivid deep-sky imaging from light-polluted locations. Its high-contrast passband allows astrophotographers to simulate the Hubble SHO palette using a one-shot color camera.

This clip-in format is engineered for direct insertion into compatible Canon APS-C camera bodies without modification. Whether capturing emission nebulae or supernova remnants, the L-eNhance delivers crisp, narrowband-quality images—perfect for advanced imaging with minimal setup.
