ANTLIA OIII 3nm FAST ULTRA NARROWBAND FILTER Size:2" Double layer for a betterThe Antlia OIII 3nm FAST ultra narrowband filter boosts the contrast of emission nebulae and supernova remnants for professional results, even under a bright sky affected by light pollution. The FAST series of filters are designed for telescopes with a focal ratio between f 2. 6 f 3. 6. Blueshift data indicates that at a focal ratio of f 2. 6, the angle of incidence of the light cone is 10 and its bandwidth shifts 2. 2nm to shorter wavelengths.
