ANTLIA SII 3nm FAST ULTRA NARROWBAND FILTER M77 The ED lens reduces theThe Antlia SII 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.
