The Chroma LRGB Astronomy Filter Set – 1.25" is a premium broadband filter solution designed for astrophotographers demanding exceptional optical quality, accurate colour reproduction and industry-leading contrast performance. Manufactured in the USA by Chroma Technology, these filters are trusted worldwide by advanced imagers, universities and professional observatories.

Featuring advanced hard-sputtered coatings and precision-engineered passbands, the Chroma 1.25" LRGB filter set delivers extremely high transmission efficiency with excellent out-of-band blocking for cleaner stars, richer colour balance and improved deep sky imaging performance.

Unlike lower quality filter sets that can suffer from reflections, halos and inconsistent colour response, Chroma filters are engineered for stability and long-term imaging precision. The carefully matched RGB channels provide natural colour reconstruction while the luminance filter maximises fine detail and signal-to-noise ratio.

The 1.25" mounted format is ideal for compact monochrome CMOS and CCD imaging systems, making this set an outstanding choice for high-performance deep sky astrophotography.
