Optolong L-Pro Filter 77mm

Optolong L-Pro Filter 77mm: Natural Colors Under City Lights

The L-Pro is Optolong's most refined broadband filter: multiple precisely placed passbands block the emission lines of streetlights and natural airglow, while keeping the color balance virtually neutral. This makes it the light pollution filter for objects that need to retain their color: galaxies, star clusters, reflection nebulae, and the Milky Way.

This 77mm version screws directly onto the filter thread of your camera lens: made for widefield and Milky Way photography with camera and lens.

Neutral where other filters color

More aggressive filters like CLS or UHC give a clear color cast and cost signal on broadband objects. The L-Pro preserves subtle hues and thus also saves processing time.

Solidly built

The optical glass is multi-coated against reflections and housed in a thin, black anodized metal ring with laser engraving.

Featured accessories

For emission nebulae with maximum contrast, a dual-band filter like the Optolong L-eXtreme is the logical addition.

For whom yes and for whom no

• ✓ Photographers of galaxies, star clusters, and reflection nebulae
• ✓ Those who want a natural color balance under city lights
• ✗ For exclusively photographing emission nebulae: a dual-band filter provides more contrast
