Astronomik UHC-E Filter

This filter is designed specifically for Canon EOS APS-C cameras. It features a clip-in design that fits directly into the camera body, making it incompatible with full-frame Canon models or other camera brands.

The 45nm bandwidth is wide enough to allow plenty of starlight through for shorter exposures, yet narrow enough to effectively block common sources of light pollution like mercury and sodium vapor streetlights. This balance makes it an excellent choice for urban astrophotography where you need to boost contrast without losing too much signal.

No, this is an emission-line filter designed primarily for emission nebulae and comets. Because galaxies emit a broad spectrum of light, this filter will block much of their signal; for galaxies, you are better off using a clear or UV/IR cut filter.

While it is optimized for light-polluted areas, it can still be used in dark-sky locations to increase the contrast of emission nebulae. However, you may find the effect less dramatic than when shooting under urban skies where the light pollution suppression is most needed.

No, the Astronomik UHC-E filter does not include a storage case. We recommend keeping it in a dedicated filter box or your camera bag's accessory pouch to prevent scratches and dust accumulation when it is not installed in your camera.
