Svbony LRGB 1.25" is a complete set of LRGB filters dedicated for use in professional astrophotography sets equipped with monochrome cameras, both with CCD and CMOS matrices.

Each of the filters included in the set was made on a carefully selected optical substrate additionally covered with an anti-reflective layer, which, in addition to improving the contrast and detail of the image, is a layer that protects the surface from minor damage. The transmittance ranges of the individual filters were selected in such a way that it was possible to achieve equal weights between the R, G and B channels. Importantly, these filters are also characterized by high transmittance for the Hα, S II and O III spectral lines.

Attention! LRGB 1.25" telescopes are not recommended for use in visual observations. Under no circumstances should they be used as eye protection when observing the Sun!
