The Astronomik UHC-E Clip-Filter EOS R APS-C (Astronomik, SKU: 10220086 / 8h11ux) is a light pollution suppression filter designed for Canon EOS R APS-C mirrorless cameras. The UHC-E model was developed for imaging emission nebulae and comets under light-polluted skies. Thanks to its 45 nm Full Width Half Maximum bandwidth, the filter significantly increases the contrast between objects and the sky background, while at the same time passing more starlight than the narrower UHC filter. Its transmission characteristics also include the typical emission bands of comets, which makes them easier to photograph.
