Remove Light Pollution While Keeping Your Images Bright
Light pollution limits how much of the night sky we can see and photograph. When imaging with a color camera in light polluted areas, skyglow degrades image quality. Light pollution filters help to selectively block light emitted from common streetlights and other ambient lighting. But most light pollution filters greatly compromise the total light throughput, causing dim images, and negatively impact the color balance, causing images to appear too green or blue.
The Light Pollution Imaging Filter for RASA “surgically” removes unwanted light pollution while preserving as much of the useful spectrum as possible. That means you’ll still retain over 90 percent of the light captured by your telescope at many wavelengths.
