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.
Perfect for Imaging Colorful Nebulae and Galaxies
The Light Pollution Imaging Filter 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. Unlike other light pollution suppression filters, the Celestron LP Imaging Filter maintains a relatively neutral color balance so you can bring out subtle color in galaxies and other faint deep sky objects. Multiple layers of specially-formulated dielectric coatings provide the desired transmission, while anti-reflective coatings minimize star halos and internal reflections.
Individually Tested for Quality
Every Celestron Light Pollution Imaging Filter is tested individually for light transmission. Inside the box, you’ll receive a graph detailing the actual transmission spectrum for your specific filter. Also included is a clear plastic case to protect the filter when not in use.
