A filter with incredible light pollution cut off characteristics
The new H-Alpha passfilter enables high-contrast deep sky images of H-II regions
The H-Alpha filter shares the same outstanding features as all the other Astromania imaging filters
Unmatched optical quality and high efficiency hardened multicoatings result in the sharpest and highest contrast images possible
The filter is used as an extreme anti light-pollution filter and for contrast-enhancement of emission nebulae and other astronomical objects bright in the infrared
