Astronomik CLS CCD clip-on filter for NIKON Z XL
Astronomik CLS-CCD Nebula filter for astrophotography
This filter is suitable for photographing nebulae, star clusters and also galaxies even from close-up. The contrast of deep sky objects is improved, as the light from artificial illumination is blocked as far as possible. This allows you to expose 3 times longer before the sky background lightens. In this way, the CLS CCD filter improves results whether you are working near cities or under dark skies away from towns.
The CLS CCD filter is ideal for photographic use on telescopes of all apertures with focal ratios from f/15 to f/2.
How the CLS-CCD filter works
The filter completely blocks the emission lines of low and high pressure lamps (mercury (Hg) and sodium (Na)) and the glare lines of air. This improves contrast everywhere, even under dark alpine skies.
All important emission lines of astronomical objects are transmitted. The filter also blocks infrared light (IR light). Therefore, an additional IR blocking filter is not necessary.
Astronomik XL clip-on filter for Nikon Z Full Frame System Cameras
The clip-on filter is optimized for use with normal camera lenses and for use with telescopes.
The filters sit securely and stress-free on the camera. Mounting and dismounting is easily done with your finger - no tools required! There is no need to modify the camera to use the filters.
The challenge:
do you own a camera and also use it for astrophotography? Then you have probably already encountered the following problems:
Large filters in screw-in cells are very expensive.
Filter holders cannot be used between the camera body and the objectives, because then infinity focusing is no longer possible.
In very fast telescopes with short working distance, not even a filter box or a filter wheel can be used, since the distance to the corrector can no longer be maintained.
With long exposure times, the chip in your camera gets dusty.
With the Astronomik clip-on filter you get rid of all these limitations at a stroke.
Astronomik clip-on filters are laser-cut on state-of-the-art machines and can be inserted directly into the camera body in a matter of seconds. No conversions are necessary and all functions (focus, aperture, image stabilization) remain completely intact.
The clip-on filters are optimized for use with normal camera lenses and for use with telescopes. The filter used provides excellent protection against dust, preventing dust from entering the sensor during long exposures.
Astronomik clip-on filters are registered as utility models with the European Patent Office.
Compatibility:
Nikon Z full frame mirrorless cameras Z5, Z6 and Z7 are compatible, other bodies have not been tested by the manufacturer yet.
The filter is not compatible with the original Nikon Z 2.0x teleconverter.
Due to the very small space inside the camera, clamp filters can add minimal obstruction at the edge of the field, which is easily corrected with the normal flat field.
Astronomik recommends the CLS CCD filter as the first filter.
This filter largely suppresses artificial light pollution and natural airglow. With this filter you get a dark sky background, so you can expose longer and make fainter objects visible. The filter is optimized so that objects appear in natural colors, i.e. as they would be perceived by the human eye if it were much more sensitive.
Important: The basic CLS filter does not have built-in IR blocking. Therefore, for a converted ("astromodified") camera the CLS-CCD is required!
