Sky Rover Optics 2" Astronomical High Contrast Visual Filter is a broadband astronomical filter designed for visual observations. It has been developed to reduce the effect of light pollution caused by urban lighting, street lamps and other artificial light sources. As a result, it increases the contrast between nebulae and the sky background, making it easier to see subtle structures of deep-sky objects even under moderately light-polluted skies.
