Baader UBVRI Photometric Filters

Baader Photometric UBVRI filters follow the Johnson-Cousins UBVRI system used for standard stellar photometry. They allow amateur and research observatories to measure brightness and colour indices that can be compared with catalogue values and professional results.

The U, B, V, R and I filters are sold individually or as a complete UBVRI set. They are a common choice for variable star monitoring, scientific outreach projects and university teaching labs.
