Astrodon is known for designing the best performing, most durable filters for astrophotography and research.

For astrophotography, Astrodon LRGB filters simplify imaging by allowing you to take one exposure time for each color, only one corresponding dark exposure time and nearly equal color combine weights in post-processing. The resulting color balance is superb, which is why so many of the top imagers now use Astrodon LRGB filters. These designs eliminate halos around bright stars that detract from the beauty of the galaxy or nebula.

Astrodon Narrowband filters set the highest, consistent performance level, and are spectrally narrower than most other filters, leading to the best contrast and faintest structures in your nebula. Astrodon has a performance guarantee of >90%T at the emission line on every box.

UBVRI and Sloan PHOTOMETRIC filters are 100%-coated using no colored glass for long-term durability that is so critical for consistent, long-term research. They have the highest throughputs available for better signals and fainter objects and are becoming widely accepted in professional observatories in sizes up to 150mm. Some of these larger filters are used on the famous Palomar 200" telescope, at the MacDonald Observatory, Las Cumbres Observatory of Global Telescopes, AAVSO and universities and research organizations worldwide.

All Astrodon astrophotography filters are manufactured in the U.S. with superb quality control using 100% hard-oxide sputtered coatings. Astrodon filters cost a little more because of the benefits that their high performance and great durability provides. Filters are a critical part of telescope systems. They are the "spark plugs" that make the "engine" go. Step up to Astrodon and see the difference.
