The Chroma LRGB Astronomy Filter Set – 36mm is widely regarded as one of the finest broadband filter sets available for serious astrophotography. Designed and manufactured in the USA by Chroma Technology, these premium unmounted filters deliver exceptional transmission, outstanding colour separation and industry-leading optical consistency for demanding monochrome imaging workflows.

Engineered with advanced hard-sputtered coatings, the Chroma 36mm LRGB filters provide extremely high transmission efficiency with excellent out-of-band blocking, helping astrophotographers achieve cleaner stars, richer colour balance and superior contrast across galaxies, nebulae and deep sky targets.

Unlike lower quality filter sets that suffer from spectral drift, halos or inconsistent colour response, Chroma filters are designed for long-term stability and precision imaging performance under varying environmental conditions. Their carefully coordinated passbands ensure accurate RGB colour reconstruction while the luminance filter maximises fine detail and signal-to-noise ratio.

The 36mm unmounted format is ideal for modern monochrome CMOS and CCD astronomy cameras paired with electronic filter wheels, making this set a superb choice for advanced astrophotographers building premium imaging systems.
