Light Pollution Imaging Filter, Rowe-Ackermann Schmidt Astrograph (RASA) 8 Overview: Enhance your 8” Rowe-Ackermann Schmidt Astrograph (RASA) by blocking light pollution, improving image contrast, and darkening the sky background. This filter selectively blocks wavelengths of light from sources of light pollution, such as streetlights, not broad regions of the spectrum. Does not block wavelengths associated with emission nebulae, keeping your nebula images bright and detailed. Fits into the 8” RASA’s integrated filter mount, maintaining peak optical performance. Optically flat surfaces free of defects, constructed of Schott glass with anti-reflection coatings. Show more
