The 1.25Inch Moon & Skyglow is a multi-bandpass 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. The filter effectively filters out selective wavelengths of low-pressure sodium and other man-made sources typically used in street lighting. It enhances the views of deep-sky objects by increasing the contrast of these objects against the background sky. While nebula filters transmit only a few select wavelengths corresponding to various atomic lines， this filter transmits a large portion of the continuous spectrum while blocking a few select lines of the more common man-made light. Neodymium provides a unique， selective， blocking feature in that this element greatly reduces glare without reducing important color and brightness variations.
