Colour Magic H-alpha SII OIII 3nm 2"

The Askar Colour Magic 3nm narrowband filter set comprises three individual ultra-narrow 3nm filters (H-alpha, SII, and OIII) designed for professional deep-sky astrophotography with color cameras or monochrome cameras. Each filter isolates specific emission lines at their center wavelengths (656.3nm for H-alpha, 672nm for SII, and 500.7nm for OIII) with over 90% peak transmittance, enabling high-contrast imaging of emission nebulae, planetary nebulae, and supernova remnants even in light-polluted areas. The ultra-narrow 3nm bandwidth and optimized halo control effectively reject light pollution while maintaining exceptional contrast, allowing astrophotographers to capture fine detail and create stunning Hubble Palette SHO images.
