Celestron RASA 8 Light Pollution Imaging FilterCelestron Rasa 8 Light Pollution Imaging Filter For the vast majority of us, we live in cities or locations with a lot of street lights. Light pollution in the night sky can significantly degrade contrast in astronomical images. This is especially true when using very fast telescopes like the Celestron 8 RASA because the sky background saturates very quickly. The noise of the light pollution overwhelms the signal from the celestial object you are
