A set of three RGB filters in the Deep-Sky version, in a 1.25 "frame. Recognized as the best on the market. • transmission up to 95% • ultra sharp, point star images • high contrast • optimized spectral windows to obtain the largest number of photon counts on the matrix • diffraction-limited accuracy • parchocal with other Astronomic filters • resistant to moisture, scratch, does not age • Soda lines are not passed Under conditions of light pollution, the manufacturer suggests using a CLS-CCD filter instead of L (luminance). Thanks to this, the quality of the material increases significantly.
