Product description

H-alpha: This filter is suitable for photographing hydrogen nebulae from areas with light pollution, but also from places with dark skies. The contrasts between objects that glow in H-alpha light and the sky background are greatly enhanced.

Antlia nebulae filters offer extreme contrast. This enables astrophotographers to achieve excellent results even in the presence of significant stray light from cities or the Moon. Antlia guarantees a transmission of at least 88 per cent within a 1 nm bandwidth around the central passband. This makes the narrow-band filters particularly suitable for fast telescopes and objectives. Even at an extreme aperture ratio of f/3, there is only a minimal loss of transmission.
