Baader Yellow 495nm Long-Pass Filter - Round Mounted - FCFY- William Optics Accessories Universal AC adapter includedAbout the Baader Yellow 495nm Long Pass Filter Round Mounted Baader Planetarium astronomy filters by far supersede the mediocre quality of common "flame polished" color filters. A fine optical polish and 2 mm thick glass allows the Baader Yellow Filter to be inserted anywhere into the optical path without introducing astigmatism or other defects.
