VAONIS CLS filter pre Vespera (AC023)

The VAONIS CLS Filter (AC023) is a high-quality light pollution filter specifically designed for the Vaonis Vespera smart telescope. It effectively suppresses artificial light from mercury vapor, sodium vapor, and other urban sources, enhancing contrast for deep-sky observation. The filter features multi-layer dielectric coatings on high-quality optical glass, ensuring excellent transmission at key emission lines (H-alpha, H-beta, OIII) while maintaining natural color balance.
