ANTLIA OIII 3nm PRO ULTRA NARROWBAND FILTER Solar A deformation like this canThe new Antlia O III 3nm PRO ultra narrowband it is the latest filter produced by Antlia. This filter boosts the contrast of emission and planetary nebulae, Wolf Rayet nebulae and supernova remnants for professional results, even under a bright sky affected by light pollution. The 3. 0 nm band pass is only 1% of the entire visible spectrum, increasing the signal to noise ratio and delivering high contrast images and extremely dark backgrounds. To even
