Fight back against light pollution! The Garrett Optical 1.25-inch Skyglow LPR (Light Pollution Reduction) is designed to filter out a few specific wavelengths from streetlights, as well as skyglow from Earth's Moon. Performs well in our 70mm and larger binoculars that are threaded for filters, though the greatest benefit will be seen in 100mm and larger models. Performs extremely well in telescopes, and is also useful for enhancing planetary detail. Each filter comes with its own padded plastic case. Sold individually.
