Astronomik L1 Filter

The L1 filter acts as a luminance channel, blocking UV and IR light while allowing visible light to pass through. It is designed to sharpen your images and prevent star bloating caused by light outside the visible spectrum.

Yes, the L1 is specifically optimized for optical systems that use correctors, flatteners, or reducers. Its design helps minimize reflections and halos that can often occur when using these additional glass elements.

Absolutely. The filter provides high-contrast, clear views suitable for both planetary detail and deep-sky objects, making it a versatile choice for a wide range of astrophotography.

Yes, because it sits in the optical path, it acts as a protective barrier for your camera sensor. It helps keep dust and moisture off the sensor surface while you are imaging.

The filter is engineered with high-quality multi-coatings to suppress reflections and halos. This ensures that even when bright stars are present, they remain sharp and clear rather than appearing bloated or distorted.

The 1.25-inch size is a standard thread size for most eyepieces and filter wheels. It is compatible with the vast majority of entry-level and intermediate telescope setups.
