Product Description
The Antlia 8-EL UHC Pro Visual Enhancer filter is a high-performance optical filter designed for visual observation of celestial objects.
This filter is designed to combat moderate light pollution while maintaining excellent color balance, making it ideal for visual observation of emission nebulae, planetary nebulae, and other objects. It selectively enhances key emission lines through its high-transmission design. The combination of high transmission (>95%) and sodium-light suppression allows observers to perceive fine structural details in Planetary nebula, emission nebula targets, even under moderate light pollution.
