Optolong CLS Clip Canon EOS Full Frame

Optolong CLS Clip Canon EOS Full Frame: light pollution suppression from within the body

You click a clip-filter into the camera body in seconds, directly in front of the sensor. Then you simply mount your lens or telescope adapter: the filter protects the sensor and filters every image you take. This CLS filter (City Light Suppression) blocks the disruptive emission lines of street lighting, while allowing the light from nebulae and galaxies to pass through.

The result under a city sky: a darker background, more contrast, and longer usable exposure times before light pollution overwhelms the image.

Click and shoot

The filter is installed and removed without tools and leaves camera functions untouched. The filter works with lenses and telescope adapters; for mirrorless adapters, check that there is enough space for the rear lens.

Widely applicable

CLS is a broadband filter suitable for emission nebulae, but also useful for galaxies and star clusters under moderately light-polluted skies. For unmodified cameras, this standard version is the right choice.

Featured accessories

For darker skies or nebula photography with more contrast, the Optolong UHC clip or an L-series filter is the next step.

For whom yes and for whom no

• ✓ Deep-sky photographers shooting from the city or outskirts
• ✓ For those who want to continue using any lens without modification
• ✗ Owners ofastro-modified cameras: then choose the CLS-CCD version with IR blocking
