Chroma 50mm LRGB Filter Set
Chroma 50mm LRGB Filter Set is specifically designed for deep space CCD/CMOS imaging. This filter set comes with four 50mm unmounted filters: Luminance, Red, Green, and Blue.
Chroma manufactures the highest quality astronomy filters with durable, sputtered hard coating using single substrates of the best glass, eliminating the need for laminations. All primary filter coatings are applied on the front surface and anti-reflection coatings on the rear surface to prevent ghosting and to maximize transmission.
Highly precise and accurate, the bandpass of these filters remain spectrally stable and do not drift in response to extreme temperature fluctuations or changes in humidity.
