Astronomik MC-clear Filter
The Astronomik MC-(multicoated) Clear filter serves dual purposes: as a dust protector or to maintain the optical depth of your imaging system.
Dust protection: The robust coating ensures scratch resistance and durability, making the Astronomik MC-Clear filter the perfect choice for protecting your optics or sensors (e.g. Schmidt-Cassegrain telescopes, Schmidt-Newton telescopes, Maksutov systems, and DSLR cameras) from dust particles and airborne contaminants without affecting the sensitivity of the camera or the eye, altering colors or destroying the optical performance of your system.
Parfocality: The Astronomik MC-Clear glass is manufactured to the same high standards as other Astronomik filters, ensuring it is parfocal with other Astronomik filters. This means it can be used interchangeably with other filters without affecting the focus.
The filter is multicoated to prevent unwanted reflections and does not block infrared (IR) or ultraviolet (UV) light.
Astronomik MC-Clear filter are highly regarded by camera manufacturers worldwide for their superior coating and scratch resistance, available in various custom diameters.
Main use
The Astronomik MC Clear is made by the same high-end process as all other Astronomik filters. The coating has the same scratch resistance and the substrate has the same high quality. Because of this it is parfocal with all other Astronomik filters and can be used in any optical system for dust protection without modifying the spectral characteristics and without destroying the optical performance of your system.
Other uses
- As a dust protection of Schmidt-Cassegrain, Schmidt-Newton or Maksutov system or as a dust protection in front of DSLR camera.
- As an alternative instead of the UV-IR-Blocker if your system has no refracting elements.
-
Alternatives
You should think about using the IR-blocker or even the UV-IR blocker if you have a system with any refracting elements.

Clip-Filters for mirrorless Canon EOS R APS-C cameras
Canon EOS R APS-C series cameras are an excellent choice for astrophotography. With Astronomik Clip-Filters, you can use our full range of filters with your camera to capture stunning images. Whether paired with a camera lens or a telescope, our clip filters ensure maximum image quality and performance from your setup.
The Astronomik Clip-Filters offer a number of practical advantages that make them an ideal choice for astrophotographers:
- Installing and removing the Astronomik Clip-Filter is very quick and easy and requires no extra tools or modifications to the camera body. They can be changed at any time, even at night.
- All lens functions, such as focus, aperture, and image stabilization remain fully functional.
- The Astronomik Clip-Filters are held securely in place without stressing the high-quality glass.
- The Astronomik Clip-Filters are designed and optimized for use with both standard camera lenses and telescopes.
Through the Astronomik Clip-Filters, we were able to solve several common issues faced by astrophotographers:
- Large filters for large camera lenses are very expensive.
- Using a filter holder between the camera body and the lens prevents focusing to infinity.
- For very fast telescopes (low f-number) like the Vixen R200SS or the Takahashi “Epsilon” astrograph, a filter drawer or filter wheel can not be used because the distance to the corrector lenses would be changed.
- Long exposure times lead to dust settling on the camera’s sensor chip.
Additionally, all Astronomik EOS R APS-C Clip-Filters serve as an excellent dust shield, protecting the sensor during long exposures. If you only need a dust shield without filtering effects, the Astronomik MC-Clear EOS R APS-C Clip-Filter is the right choice.
Use Astronomik filters for your Canon EOS R APS-C camera and enjoy marvelous images with an ultra-light equipment!
NOTE: Please store the Clip-Filter in the supplied storage box and do not leave it in the camera permanently.

Astronomik filters are diffraction-limited, ensuring that the optical performance (resolution and contrast) of your telescope is not compromised. Thanks to the high-precision machining of the glas substrate, all Astronomik filters are parfocal. The wedge errors are far below all common tolerances. Therefore, all issues concerning focal distances and the exact alignment of images from each color channel are effectively eliminated.
All Astronomik filters are ideal for modern cameras, including both CMOS- and CCD-based models, ensuring you capture the best possible images with your equipment. Sharpness, contrast, and the absence of any reflections and halos are guaranteed. Even with bright stars in the field of view, nebulae and galaxies will be captured with the finest structures. The Astronomik MFR and MaxFR coatings are designed for optimal performance across a wide range of focal ratios of the optics used.
Every Astronomik filter undergoes a rigorous quality control process before delivery.
