Product description

Planar polished for highest image quality. For observations of planetary nebulae with highest image contrast!

Baader OIII filters are blocked across the entire visual spectrum. This eliminates the irritating coloured halos that are often seen with OIII filters with less sophisticated coating technology at important OIII sources.
