UHC Light Pollution Clip Filter for Canon FF Cameras

The UHC (Ultra High Contrast) broadband filter is designed to improve the visibility of various deep sky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

Main Use and Performance

  • Suitable for color CCD cameras and unmodified DSLRs
  • UHC with narrower passband provides higher contrast than CLS. Thus it is more suitable for urban environment where you suffer from severe light pollution.
  • UHC has a substantial red passband and offer superb views for objects like the Orion Nebula (M42)
  • Light pollution filters do not eliminate the effects of light pollution or increase the object's brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.

Format

This filter is sized to clip into a Canon full frame camera.
