Optolong LRGB 2 "is a set of four professional astrophotographic filters dedicated to cooperation with monochrome cameras.

All filters are characterized by high efficiency, exceeding 95%, in the maximum transmission band, and thanks to the use of a very good glass substrate and covering the surface with a full multilayer coating, the resulting image is extremely vivid and contrasting.

The separation of the transmission maximums 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 lamps, which constitute the main part of the light pollution.
