Sky Rover Optics 56 mm UHC Filter is an Ultra High Contrast astronomical filter designed for observing nebulae under light-polluted skies. The filter reduces the effect of artificial lighting, such as street lamps and urban illumination, increasing the contrast between nebulae and the night-sky background. This makes it possible to see more details of nebular structures during visual observations.
