Filter Pack Optolong L-Quad Enhance + L-Para-L 2" - Astrophotography in city and polluted skies

Optolong L-Quad Enhance + L-Para-L 2" Filter Pack

The ultimate combo for astrophotography with color cameras under urban skies.

This exclusive pack brings together two of the most valued filters for astrophotographers using OSC (One Shot Color) cameras under skies with moderate to intense light pollution. By combining the ** Optolong L-Quad Enhance** filter with the innovative **Optolong L-Para-L**, you will capture images with greater contrast, color and detail without the need for mosaic or processing sacrifices.

what's included in this pack?

✅ Optolong L-Quad Enhance 2" filter

Multi-band filter that blocks mercury and sodium light (LED lanterns included) while allowing key emission lines to pass through: H-Alpha, H-Beta, OIII and SII. Ideal for emission and planetary nebulae, especially in urban or suburban areas.

✅ Filter Optolong L-Para-L 2"

Luminance filter designed to replace a traditional L, but with spectral curves better adapted to color sensors. It gradually suppresses the areas of the spectrum with more contamination, generating cleaner and more contrasted images without altering the color balance.

Advantages of using this pack:

🔭 Designed for color cameras (OSC)

Both filters have been optimized to maximize the performance of Bayer sensors in color astrophotography cameras.

🌆 Excellent results under polluted skies

They effectively reduce light pollution without the need for complex calibration processes.

🌌 Ideal for nebulae and large fields

Thanks to its multi-bandpass, you can capture emission-rich regions such as Orion, the Swan or the Galactic Center with a single shot.

High-quality glass with multi-layer coating

Manufactured with Schott glass and dielectric treatments that guarantee high transmission (>90%) and minimal internal reflection.
