The Antlia 8-EL UHC Pro Visual Enhancer is an advanced multiband filter for visual observation of deep-sky objects, designed for maximum contrast and high transmission in the key emission lines of nebulae. It effectively reduces the influence of moderate sky light pollution while maintaining the natural color balance of observed objects.

The filter transmits more than 95% of the light in the eight main emission lines: H-alpha, H-beta, OIII, NII and SII, which allows for clear visibility of nebula structures even in city conditions. By suppressing sodium light, it significantly improves the visibility of details in planetary and emission nebulae.

It is recommended for use with large aperture telescopes (at least 8") to compensate for the loss of sensitivity of the human eye in low light conditions. The filter is an excellent tool for visual observers who want to increase the contrast of nebulae without losing the naturalness of the image.
