ZWO LRGB 1.25 "is a set of four professional astrophotographic filters dedicated to cooperation with monochrome cameras.

All filters are characterized by high, exceeding 90% efficiency in the maximum transmission band, and thanks to the use of a very good Schott glass substrate and covering the surface with a full multilayer coating, the resulting image is extremely Vivid and contrasting.

The separation of the maximum transmittance for the G and R filters was selected in such a way as to effectively eliminate the signal coming from the spectral lines of sodium and mercury lamps, which are the main part of the light pollution.
