This four-filter 36 mm Baader LRGB set is intended for colour imaging with a monochrome CMOS or CCD camera. It contains luminance, red, green and blue filters, with unmounted construction and 2 mm glass thickness.
Spectral coverage
The manufacturer lists L at 420–685 nm, R at 595–690 nm, G at 490–580 nm and B at 400–510 nm. The luminance filter combines UV/IR rejection with a stated 98% transmission across its visible passband. The RGB channels are balanced for similar exposure times.
Coating and optical finish
Reflex-Blocker hard coatings reduce reflections, while Life-Coat sealed coating edges and blackened filter edges address edge reflections and durability. Each filter is plane-optically polished. The black outer-rim indicator identifies the telescope-facing side.
Camera and optical compatibility
Baader specifies use from f/15 to f/1.8. The filters are designed for parfocal operation, but residual colour focus in a telescope can still require individual focus offsets or refocusing. The 36 mm version is unmounted and needs a matching filter holder.
