The DW mechanism must operate at both room temperature and at 35K. WebbNarrowband filters are narrow in order to pass a very restricted band of wavelengths around specific emission lines of Ha, SII, OIII. Ha (Hα) 656nm = Hydrogen-Alpha. S-II 672nm = Sulfur-II. O-III 496nm = Oxygen III. As their name suggests, narrowband filters have a “narrow” bandpass. mcheli mod 1.12.2 curseforge
