The Chroma SHO 3nm Imaging Filter Set is a premium narrowband imaging solution designed for capturing emission nebulae with unprecedented detail and contrast. This unmounted square filter set includes three separate 3nm bandpass filters: Sulfur-II (SII) isolating 671.6/673.1nm doublet emissions, Hydrogen-alpha (Ha) at 656.3nm peak transmission, and Oxygen-III (O-III) at 500.7nm, enabling the classic Hubble Palette color mapping. Constructed with Chroma's durable sputtered hard coatings on single glass substrates with front-side coatings and rear anti-reflection coatings to maximize transmission and prevent ghosting, these filters deliver spectrally stable performance across temperature fluctuations.
