Optolong Filters Clip Filter for Canon EOS APS-C UHC

Optolong Filters Clip Filter for Canon EOS APS-C UHC is a high-quality clip-in filter that plugs directly into the body of Canon APS-C DSLR cameras. The filter is specially designed to darken the sky background to enhance the contrast of deep-sky objects, even when photographing from light-polluted environments.

The UHC (Ultra High Contrast) design allows the main emission lines of nebulae to pass through, such as H-alpha, H-beta and OIII, while effectively blocking interfering artificial light - including sodium and mercury lamps. As a result, nebulae and galaxies become more clearly visible and longer exposure times can be used without ‘burning’ the image.

Because the filter plugs directly into the camera, you can combine it with virtually any Canon EF or EF-S lens, as well as telescopes via a T-ring. This makes the Clip Filter ideal for those who want to shoot flexibly with different lenses and setups. The compact design also protects the sensor from dust during use.

Application
This filter is ideal for astrophotographers working with a Canon APS-C DSLR and suffering from light pollution. It is particularly suitable for nebulae, star clusters and galaxy fields. For visual use, this filter is not suitable; it is specifically designed for photography. When used with wide-angle lenses, be aware that vignetting may occur, especially at very short focal lengths.
