The Astronomik CLS CCD filter is designed for use with cameras that are intended for astronomical use. It enhances the contrast between all deep-sky objects and the sky background, making it ideal for astrophotography under light polluted skies.
Its wider transmission range compared to UHC filters allows a greater amount of light to pass through, resulting in less dimming of stars.
The Astronomik CLS CCD filter is optimized to block as much unwanted light as possible while allowing the maximum amount of light from the astronomical objects to pass through. The Astronomik CLS CCD filter completely blocks the emission lines of artificial light sources such as streetlights (e.g., high- and low-pressure sodium (Na)- and mercury (Hg)-vapor lamps) as well as all lines of natural airglow.
The Astronomik CLS CCD filter is suitable for DSLR, CMOS, and CCD cameras and can be used with telescopes or lenses with focal ratios from 1:1.8 to 1:15.
The integrated infrared (IR)-blocking layer makes it suitable for use with cameras without their own IR-block filter.
Other uses
The 1.25" and 2" socket models can be used for observations from light-polluted areas.
For color images from emission line objects, the Astronomik CLS CCD filter is an excellent choice for the luminance channel.
Alternatives
For cameras with a built-in IR cut filter or for visual observation, the Astronomik CLS filter is a more budget-friendly option.
Suitability of the Astronomik CLS CCD filters
- CMOS and CCD photography: Very good blocking of light-pollution
- DSLR photography (original): Good, color balance is shifted but contrast is enhanced
- DSLR photography (astro-modified): Very good, color balance is close to perfect
- DSLR photography (MC-modified): Very good, color balance is close to perfect
Clip-Filters for Sony Alpha 7 and Alpha 9 cameras
Since 2007, we have offered our extremely popular Astronomik Clip-Filters. The complete range of Astronomik filters is available as Clip-Filters for the Sony Alpha 7 and Alpha 9 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.
Due to the very tight Sony bayonet and the limited space inside the camera, the Astronomik Sony Alpha 7 Clip-Filters cause a minimal obstruction in the corners. But this can be easily corrected by flatfielding.
Additionally, all Astronomik Sony Alpha 7 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 Sony Alpha 7 Clip-Filter is the right choice.
Use Astronomik filters for your Sony Alpha 7 or Alpha 9 camera and enjoy marvelous images with ultra-light equipment!

Technical Data
- 95% transmission at 486nm (H-beta)
- 95% transmission at 496nm (OIII)
- 95% transmission at 501nm (OIII)
- 97% transmission at 656nm (H-alpha)
- Transmission range: 450 to 520nm and 640 to 690nm
- Glass thickness: 1mm (except Astronomik OWB Type 3 and XT filters)
- Finely polished optical glass, free of any striae, residual stresses, and bubbles
- Extremely scratch-resistant and durable coating
- Completely resistant against high humidity and aging effects
- Parfocal with other Astronomik filters
- Diffraction-limited
- Optimized spectral windows
- Delivered in a high-quality, long-lasting filter box
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.
