Astronomik L-2 Filter

The L-2 filter is designed to capture the luminance channel in astrophotography. It blocks ultraviolet and infrared light while allowing visible light to pass through, which helps maximize signal and photon counts for clearer, sharper images.

No, the filter utilizes advanced coating technology specifically engineered to eliminate halos and reflections. Even when imaging fields with very bright stars, you should see clean, artifact-free results.

Because the Astronomik L-2 is designed to be parfocal with other filters in the series, you generally do not need to refocus when switching filters. This allows for a much smoother and more efficient imaging workflow.

Yes, the L-2 is engineered to perform optimally with most optical systems, including those using correctors, flatteners, or reducers. Its design accounts for the optical path changes these accessories introduce.

The filter features a high-quality optical substrate with a durable, scratch-resistant coating. It is built to withstand regular use and cleaning over the long term, backed by a 10-year warranty.
