Baader 2" Narrowband OIII Nebula Filter 10nm HBW
THE PROFESSIONAL NEBULA FILTER!
Baader 2" Narrowband OIII Filter, (10nmHBW) Optically Polished
The non plus ultra for visual deep-sky observers, offering the highest performance of all nebula filters, especially under extremely light-polluted skies.
Among the narrowest transmission band O-III filters on the market, ideally suited for CCD imaging thanks to its unsurpassed contrast.
No image degradation is perceptible even at the highest magnifications. Features the same ultra-hard, extremely durable vacuum-deposited dielectric coatings employed on the UHC-S filter.
The Baader O-III Filter effectively blocks the entire visual spectrum with the exception of the O-III transmission line, eliminating the annoying colored halos surrounding stars that
often appear through O-III filters manufactured by means of less sophisticated coating technology.
