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
