By strategically blocking these wavelengths, the filter greatly reduces the effects of light pollution without degrading overall image quality. The result is bright, detailed objects that pop off the black sky background with superior contrast.įortunately, many sources of light pollution have relatively discreet emission spectra they emit primarily at specific wavelengths of light. The Light Pollution Imaging Filter for the 8” RASA remedies this by blocking light pollution while transmitting light from deep-sky objects. The “noise” of the light pollution overwhelms the “signal” from the celestial object you are imaging, making it difficult to get the most detailed image.

This is especially true when using very fast telescopes like the 8” RASA because the sky background saturates very quickly. Light pollution in the night sky can significantly degrade contrast in astronomical images.
