Rowe-Ackermann Schmidt Astrograph (RASA) Light Pollution Imaging Filter
Take beautiful images of deep-sky objects from light-polluted suburban locations with the Rowe-Ackermann Schmidt Astrograph (RASA) using this all-new light pollution suppression filter designed by Celestron and Astrodon, a leading astroimaging filter company.
Custom fit to drop into RASA’s optical window, so you get optimum optical performance even with the addition of the filter.
Selectively removes unwanted light pollution while allowing more overall light transmission to pass through to the sensor. Provides over 90% transmission at critical wavelengths.
Maintains a more neutral color balance than other light pollution imaging filters, perfect for imaging colorful nebulae and galaxies.
Every filter is individually tested for light transmission. A graph of test results for your specific filter is included for your reference–a valuable service unique to Astrodon.
