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 to 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
Size of filter
Astronomik filters come in a wide range of standard sizes, both mounted and unmounted, to suit various optical setups and cameras.
This filter is a filter with a protective ring for filter wheels without screw thread. The glass thickness is 1mm, the mechanical thickness is 3mm, the diameter is 31mm.
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.
