Astronomik UHC-E deepsky filter (EOS-clip)

The CLS filters are general purpose deepsky filters which blocks the light from Hg and Na lamps, but transmits all the other wavelengths.

They work as a contrast enhance filter for emission, planetary nebulae and supernova remnants. They're also work for all other objects with wider spectrum as well, like stellar clusters, galaxies, open- and globular clusters if our sky is light polluted.

These filters for Canon EOS APS-C models provide many advantages. Astrophotography is possible with these filters not only using the telescope, but using standard objective lenses as well. On the other hand these narrowband filters can be used with off-axis guiders as well, as the guide star's brightness is not affected by the filter.

The OWB filter can be used to restore the original color sensitivity (white balance) of the camera after the IR blocking filter has been replaced.

Note: these filters are compatible with all Canon objective lenses except for the EF-S series, where the back lens does not fit into the camera body because of the filter.

Compatible models: 350D, 400D, 450D, 500D, 550D, 600D, 650D, 700D, 750D, 760D, 800D, 850D, 1000D, 1100D, 1200D, 1300D, 2000D, 4000D, 20D, 30D, 40D, 50D, 60D, 70D, 80D, 90D, 7D, 7DmkII
