Read here the detailed test report of Francesco di Biase from 06 November 2021 (in English): Baader Ultra Narrowband Filters Under The Sky
Mr. Francesco di Biase had the opportunity to test the new Baader Ultra Narrowband Filters 36mm in unmounted version in his small observatory with a sliding roof under a suburban sky (19.40 SQM). Among other things, the observatory is equipped with a 10micron GM2000 HPS II mount and a 12" GSO RC telescope, which he uses at full focal length with a KAI 4022 CCD sensor.
We are very pleased about the positive feedback on the new CMOS-optimized Baader 3.5 / 4nm Ultra-Narrowband Filter-Set – CMOS-optimized (H-alpha / O-III / S-II) (various versions available) and his field report.
Original: My general opinion on performance, supported by the tests carried out and my experience with other high-end products, is fully positive. I believe that they can be equated with the most famous brands, with the advantage of a cheaper price. Of course, as soon as I need them, I will seriously consider using these filters for my setup.
Have you had any experience with the new CMOS-optimized Baader filters? We are happy to receive more reviews.
