Description

🌠 Capture the cosmos like a pro—no light pollution allowed!

The OPTOLONG 2-inch L-Quad Enhance Filter (L-QEF) is a professional-grade quad-bandpass filter designed to suppress artificial light pollution and natural skylight effects. It delivers over 90% transmittance of nebula emission lines (H-Beta, OIII, H-Alpha, SII), reduces starbursts, enhances contrast and color saturation, and cuts near-infrared noise up to 1000nm. Ideal for astrophotographers shooting under Bortle scale 1 to 7 conditions, it significantly improves the clarity and detail of celestial images.
