Description
The 1.25Inch Moon & Skyglow is a multi-band pass filter transmitting a high percentage of light in the visual spectrum. The filter enhances contrast when observing brighter objects including the moon and planets. It also will suppress sky glow from artificial lighting and background glow reflected when the Moon is up. The filter has a mild effect of darkening the background of the night sky so that the fainter objects are more clearly seen contrasted against the blackness of space.
