Astronomik H-beta Filter – Enhance Contrast for Large Telescopes Size:Astronomik H-beta visual T-Mount (M42x0.75) This is a major advantageAstronomik H beta Filter The Astronomik H beta filter is specifically designed for visual observation, optimized for larger aperture telescopes. This filter enhances the H beta emission line, allowing it to pass through nearly unhindered, while blocking other wavelengths. It significantly boosts contrast for dark adapted eyes, making objects like the Horse Head Nebula observable with telescopes between 10" and 12". Main Use The ideal aperture ratio
