Baader Scientific & Photometric Filters

Baader Planetarium photometric filters let amateur and professional observatories collect calibrated brightness and colour measurements. Two standard systems are covered: Johnson-Cousins UBVRI and the Sloan Digital Sky Survey (SDSS) passbands.

The UBVRI filters are sold individually or as a set, as are the Sloan u', g', r', i', z-s' and y' filters with the complete ugriz' set. They are used for variable stars, exoplanet transits and asteroid lightcurves.
