This filter is suitable for non-modified Canon APS-C cameras and Canon cameras that still
have the first filter on the sensor or any filter that blocks infrared light.

This Optolong CLS filter does not block infrared light so a suitable infrared blocking filter should be used.

The filter works by blocking the wavelengths of mercury and sodium-vapour used in urban lighting while letting the visible and the critical OIII, H-Alpha and H-Beta bands through, allowing great versatility in terms of potential objects to image.

 Note that this Filter is not for EF-S camera Lens. You need to buy a modified Canon EF-S lens or modify the lens yourself.

Main Features:

Blocks wavelengths of mercury and sodium vapour artificial lighting, vastly reducing light pollution and skyglow: you can image from within cities.
