Astronomik L-2 Filter

Digital sensors are sensitive to ultraviolet and infrared light, which can cause blurry stars and color artifacts in your images. The L-2 filter blocks these wavelengths, ensuring only visible light reaches your sensor for sharper, more accurate results.

No, the Astronomik L-2 is designed to prevent vignetting. You can use it with wide-field setups without worrying about dark corners or reduced light transmission at the edges of your frame.

The L-2 is built with a standard aluminum frame and is compatible with both M48 and M49 threaded mounts. It is designed to integrate easily into most common astrophotography imaging trains.

A standard clear filter only protects your sensor from dust and debris. The L-2 goes further by specifically cutting out UV and IR light, which is essential for correcting the focus and color balance issues common in long-exposure deep-sky imaging.

Quite the opposite. The high-quality optical coating is engineered to maximize light transmission while minimizing internal reflections and ghosting, ensuring your final images remain clear and high-contrast.
