This filter is an ideal complement to the ProPlanet IR 742 for use with converted DSLR cameras, CCD cameras and Webcams. The effects of seeing are distinctly reduced. It is your entry into previously unknown dimensions of photography of the moon and the planets. The ProPlanet IR 807 only allows infrared light with wavelengths of more than 807 nm to pass. In this wavelength range the effects of seeing are significantly lower than in the visible spectrum of the human eye. This allows much sharper images than are usually obtained from your device and location. Another advantage is that the sky background of advanced dawn is dark and even allows photography of planets and moon at daylight.
The Astronomik ProPlanet IR 807 cuts off the visible part of the spectrum and allows the light of wavelengths longer then 807nm to pass. Due to this behavior the part of the spectrum that is most sensitive to bad seeing is rejected. This approach does a big improvement to the imaging of planets and the moon. The image is more steady than the image in the visible light.
Visual observation (dark skies): Unsuitable, the eye is insensitive at this spectrum
Visual observation (urban skies): Unsuitable, the eye is insensitive at this spectrum
Film photography: It depends,
CCD photography: Reasonable, for special IR photography (as chlorophyll)
DSLR photography (original): Unsuitable
DSLR photography (astro modified): Unsuitable
DSLR photography (MC modified): Very good, for IR daylight photography
Webcam / Video (Planets): Very good, rejects problems with seeing, particularly with telescopes larger 250 mm aperture
Webcam / Video (Deep Sky): Very good, rejects problems with seeing, particularly with telescopes larger 250 mm aperture
more then 97% transmission for wavelengths of 807nm to 1100nm
blocking of wavelengths between 350nm and 790nm
Parfocal with other Astronomik filters
Glass thickness: 1mm
Completely resistant against high humidity, scratches and aging effects
Diffraction limited, the filter will not reduce the optical performance of your telescope!
Astronomik filters are delivered in a high-quality, long lasting, filter box
Since 2008 we do ship filters with a completely new design. Any kind of halo or strange reflection is a matter of past
