【Product Description】
Designed for Achromatic and Semi-APO refracting telescopes, it effectively suppresses blue-purple chromatic aberration (CA) and improves the sharpness of planetary observation. It is suitable for the contrast enhancement of Jupiter's cloud belt, lunar surface and Martian landform. Multi-layer coating ensures high light transmission (>90%) and no glare/scattering. Compared with the traditional #12 filter, the color deviation is smaller, and it can slightly reduce the interference of urban sunlight.
