Clip-Filter system for Nikon Z Full Frame Mirrorless cameras

Do you own a Nikon Z Full Frame digital camera for astro-imaging? Then you have surely encountered the following problems:

  • Large filters for large camera lens objectives are very expensive
  • If you are using an Off-Axis Guider stars will be dimmed on your autoguiding camera when a 2" round mounted filter is threaded to a corrector being ahead of the reflecting prism from the light path. 
  • With long exposure times your camera’s sensor chip is exposed to more dust

With the Astronomik Clip-Filter System you can take care of all of these problems at once!

The patented Astronomik Clip-Filter System is black anodized aluminum and laser-cut on state-of-the-art modern machines. It can be inserted within seconds directly into the Nikon Z camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!

The filters are held in place save and secure with no stress to the high quality glass. Installation and removal are quick an easy!
The clip-filter are designed and optimized to be used with normal lenses and with telescopes as well.
Due to the very tight space inside the camera the clip filters might add a minimal obstruction at the edge of the field, which is easily corrected by normal flat fielding.

Astronomik UHC Clip-Filter Nikon Z XL

You will enjoy using your Astronomik UHC filter because you will see more stars and more details in deep-sky-objects compared to using filters from all other manufacturers.

The Astronomik UHC (Ultra High Contrast) filter allows the transmission of nearly 100% of the radiation from both O-III and the H beta lines. Though the second window for the H-alpha-line is not intended for visual observing, it is important, if the filter is used with an electronic device. All annoying, scattered light from other wavelength sources, including local artificial light pollution, is reliably filtered out. With this strong blocking of the sky background an unexpected wealth of detail becomes visible for gas nebulae and planetary nebulae.

Main use

Astronomik UHC filters’ astounding high light transmission brings better views of deep-sky-objects even to small telescopes! The high transmission of our optical glass filters means that enough light is available to allow successful visual observations with telescopes beginning at 2" (50mm) aperture. Our Astronomik filters are optimized for use with telescope focal length f / ratios of f/4 to f/15. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios of 1:2 and more come into play. Another major advantage of our Astronomik UHC filter is the high optical quality of the filter glass. When using Astronomik UHC filters you will quickly notice the same needle-sharp stars which you are familiar with from your astronomical instrument without any filter!

    Important: Full Spectrum modified cameras will need an additional IR-block-filter.
