Astronomik now produces clip-in filters for Canon EOS M-series mirrorless cameras. Prices start at €139 (about $175) for a CLS Clip-Filter. Designed to fit between most Canon lenses and its M1 and M3 camera series detectors, the filters' placement ensure minimal distortions to stars throughout your images. These filters offer the same specialized passbands as the firm's DSLR clip-in filters, including clear (CLS) with UV/IR blocking, narrowband wavelengths such as Hα, O III, S II, and many other passbands particularly useful when shooting with modified mirrorless Canon cameras.
