Omegon Duo Narrowband Filter H-Alpha/O-III - 7 nm full width at half maximum

Omegon Duo Narrowband Filter H-Alpha/O-III - 7 nm Half-Value Width

An interference filter like this one increases the contrast when photographing emission nebulae. The object stands out against the sky background and you can see details that were not visible before. This Omegon Pro Veil filter is designed for astrophotography with color cameras. This allows you to capture the light from two emission lines at the same time.

Many nebulae reveal a wealth of detail in the regions of ionized hydrogen, oxygen, or sulfur. The respective filter models in the Omegon Pro Veil filter series allow these wavelengths to pass through, but block stray light and artificial illumination.

With a low half-width of 3 or 7 nm and high transmission, you can create excellent deep-sky images with these filters, even in areas with heavy light pollution.
