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.
Additionally, it 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.
Other uses
- It is an alternative to the Astronomik IR-Block or UV-IR Block (L-1, L-2, L-3) filters for photography in systems without refracting optical elements, e.g. Newton telescopes.
Alternatives
- Use the Astronomik IR-Block or UV-IR Block (L-1, L-2, L-3) filters for photography in systems with refracting optical elements.
Suitability of the Astronomik MC-Clear filters
- Visual observation: For dust protection only
- CMOS and CCD photography: Good, to compensate the optical thickness of other Astronomik filters; dust protection
- DSLR photography: For dust protection only
- Webcam and video: For dust protection only
Clip-Filter for Pentax K-1 and K-1 Mark II cameras
Since 2007 we offer our extremely popular Astronomik Clip-Filters. The complete range of Astronomik filters is available as Clip-Filters for the Pentax K-1 and K-1 Mark II cameras.
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 cannot 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 Pentax K-1 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 Pentax K-1 Clip-Filter is the right choice.
Use Astronomik filters for your Pentax K-1 camera and enjoy marvelous images with an ultra light equipment!

Due to the high-precision machining of the carrier substrate, all Astronomik filters are parfocal with wedge errors far below all common tolerances. Astronomik filters are diffraction-limited, ensuring that the optical performance (resolution and contrast) of your telescope is not compromised. Issues concerning focal distances and the exact alignment of images from each color channel are therefore 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 coating is 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.
