Astronomik UHC Clip Filter for Canon EOS DSLR Cameras.
The Astronomik UHC ( Ultra High Contrast ) filter allows the transmission of nearly 100% of the radiation from both O-III and the H beta lines. Though the second window for the H-alpha-line is not intended for visual observing, it is important, if the filter is used with an electronic device. All annoying, scattered light from other wavelength sources, including local artificial light pollution, is reliably filtered out. With this strong blocking of the sky background an unexpected wealth of detail becomes visible for gas nebulae and planetary nebulae.
Attached is an image of the Horsehead/Flame nebula from two 10 minute, ISO800 exposures under a Tyne & Wear, Bortle 8 sky using a Canon T3 and the UHC filter.
