The Astronomik ProPlanet 807 filter is an ideal addition to the Astronomik ProPlanet 742 filter for imaging the moon and planets, especially Mars, with telescopes of 10" (250mm) aperture and larger when the seeing conditions are poor. The Astronomik ProPlanet 807 filter only allows infrared (IR) light with wavelengths longer than 807nm to pass through, significantly reducing the effects of seeing compared to the visible spectrum. This results in much sharper images than typically expected from your equipment and location. Another advantage is that it effectively darkens the sky background during advanced dawn, enabling the photography of planets and the moon even in daylight conditions.
Other uses
- It enables imaging of young stars in dust clouds and stellar nurseries.
Alternatives
If the seeing is not too bad or if your telescope has an aperture smaller than 10" (250mm), we recommend using the Astronomik ProPlanet 742 filter.
Suitability of the Astronomik ProPlanet 807 filters
- Visual observation: Unsuitable, the eye is insensitive to this spectral region
- CMOS and CCD photography: Reasonable for special IR-photography, such as imaging chlorophyll or star-forming regions
- DSLR photography (original): Unsuitable
- DSLR photography (astro-modified): Unsuitable
- DSLR photography (MC-modified): Good, for IR daylight photography, but longer exposure times
- Webcam and video (planets): Very good, effectively rejects seeing problems, particularly with telescopes larger than 10" (250mm) aperture
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!

Astronomik XT-Filters
The new Astronomik XT-Filters are specifically designed for astrophotography with wide-angle lenses, delivering sharp and crisp star images all the way to the edges of the image. Since many years, Astronomik Clip-Filters are a popular and well known tool among astrophotographers worldwide. However, when using very short focal length lenses to take widefield images, standard Clip-Filters could introduce aberrations, stretching stars in the outermost corners of the image. To solve this issue, the new Astronomik XT-Filters are coated on an extremely thin substrate of only 0.3mm or 0.5mm thickness, significantly reducing these aberrations.
Despite the reduced thickness, the Astronomik XT-Filters maintain the highest optical quality: they are finely polished, free of any striae, residual stresses, and bubbles, and are suitable for the most advanced imaging applications. The Astronomik XT-Filters are manufactured using the same durable coating technology as all Astronomik filters. They are extremely scratch-resistant, unaffected by high humidity, and do not degrade over time. This ensures they retain their performance for years. As with all our filters, we underline this promise with a 10-year warranty.
Please note that not all Astronomik filters are available as XT-versions due to the complexity of manufacturing these ultra-thin filters. Currently, filters are produced that are predestined for photography with wide-angle lenses.
Technical Data
- More than 97% transmission for wavelengths between 807nm and 1100nm
- Blocking of wavelengths between 350nm and 790nm
- 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.
