Baader Contrast Booster is a unique filter with wide applications in lunar - planetary observations. It is intended for achromatic refractors, improving the quality of images they give, including reducing chromatic aberration and improving sharpness. It is a good replacement for ND lunar filters. • improves color reproduction in achromatic refractors • allows you to use the full capabilities of the achromatic refractor • reduces chromatic aberration • enhances the details visible on the surfaces of the solar system - it works well with observations of Jupiter • can replace the classic yellow-green filter • transmission of light is 95% • improves the contrast and color of the Moon's dial • darkens the sky background • useful in astrophotography - reduces the blue light around the photographed objects (recommended in combination with an IR-Cut infrared filter) • made of neodymium glass • 7-layer back reflective coatings with a reflection coefficient of 0.2% • dielectric, 23-layer, cured front coatings • abrasion resistant filter
