Astronomik L2 Filter

Most digital camera sensors are sensitive to ultraviolet and infrared light, which can cause bloated stars and soft focus. This filter blocks those wavelengths, ensuring only visible light reaches your sensor for sharper, more accurate images.

This is a 31mm mounted filter with a T-mount connection. It is designed to integrate with standard T-rings and accessories, but you should verify that your specific camera adapter or filter wheel accepts 31mm mounted optics.

By cutting out the non-visible light that often creates a 'haze' or false color, this filter actually helps your camera achieve a more natural and neutral color balance. It is particularly effective for improving contrast in deep-sky imaging.

While it is primarily engineered for digital imaging, it can be used for visual observation to help reduce chromatic aberration in certain telescope designs. However, its main benefit is realized when capturing long-exposure data with a CMOS or CCD sensor.

Yes, it is highly recommended for one-shot color cameras. Because these sensors are sensitive to IR light, using this filter is essential to prevent star bloating and maintain color fidelity across the visible spectrum.
