The Chroma 2" LRGB Filter Set is specifically designed for deep space CCD/CMOS imaging, enabling astronomers and astrophotographers to capture vibrant, true-color images of nebulae, galaxies, and star clusters. This premium filter set uses Chroma's durable sputtered hard coatings applied to single-substrate glass with anti-reflection coatings to maximize transmission and prevent ghosting. With individual Luminance, Red, Green, and Blue filters optimized for high transmission and excellent color separation, the set delivers high signal-to-noise ratios for fine structural detail across a wide range of deep-sky objects. The parfocal design with ultra-steep bandpass transmission and low out-of-band leakage effectively reduces halos while blocking UV and IR light for pinpoint star rendering.
