Astronomik Luminance UV/IR filters are designed to deliver optimal performance with all types of telescopes, ensuring the best possible signal-to-noise ratio and the sharpest image during deep-sky imaging. The Astronomik Luminance is an advanced UV/IR blocking filter, with a transmission curve fine-tuned to match the characteristics of the optical system.
The Luminance filter is available in three versions:
- The L-1 filter has the widest transmission range. It is recommended when the optical system is completely free from chromatic aberration.
- The L-2 filter is a general-purpose filter, recommended in most cases when a corrector or focal reducer is present in the optical path.
- The L-3 filter is primarily recommended for refractors where color correction is not perfect, as this filter minimizes the blue halo around stars.
