Astronomik Planet IR Pro 807 Filter - 1.25" Mounted

The Astronomik ProPlanet 807 filter is a deal addition to the Astronomik ProPlanet 742 for imaging the moon and planets, with telescopes larger then 10" (250mm) when the seeing is poor. This filter is an ideal complement to the planet IR Pro 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 planet IR Pro 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 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.

The Astronomik ProPlanet 807 has other uses, too. It is designed to be an addition to the Astronomik ProPlanet 742, if the seeing is extremely bad and a larger telescope is used. For most cameras the exposure times doubles, compared to the Astronomik ProPlanet 742 or imaging in visible light, if the Astronomik ProPlanet 807 is used. It also darkens the background during twilight, allows imaging of bright planets, stars and comets by day and promotes imaging of young stars in dust clouds and stellar nurseries. (If the seeing is not so bad or if the telescope is smaller than 10" (250mm) we recommend the use of the Astronomik Planet IR Pro 742.)

Astronomik Planet IR Pro 807 Filter - 1.25" Mounted Features...

  • 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

Product Series

The Astronomik UV-IR Blocker lets the full range of sensitivity of the human eye (according to DIN 5031) pass, and blocks all other parts of the spectrum in the UV and IR. The Astronomik UV-IR Blocker is the ideal choice as a luminance filter for any kind of digital photography. Because of the perfect blocking of UV and IR all optical problems in these parts of the spectrum are avoided. The filter is optimized for systems with focal ratios between f/0.5 and f/50. The typical transmission is higher than 99%.

Main use

The UV-IR Blocker gives you a perfect parfocal filter for the luminance channel. It is also great as a dust protection for your telescope and camera.

Other uses

  • As a dust protection of Schmidt-Cassegrain, Schmidt-Newton or Maksutov system or as a dust protection in front of DSLR camera.
  • As an alternative instead of the IR-Blocker if your camera has a high sensitivity at short wavelengths.
  • As an alternative instead of the MC Clear if your system has any refracting elements

Alternatives

You should think about using the IR-blocker if your camera has a low sensitivity at short wavelengths. Think about using the MC Clear glass if you have a system without any refracting elements. If you do color imaging from light polluted places, please think about using the CLS CCD filter for the luminace data instead!

Suitability

  • Visual observation (dark skies): It depends, for dust protection only
  • Visual observation (urban skies): It depends, for dust protection only
  • Film photography: It depends, for dust protection only
  • CCD photography: Very good, if used with optics which contain refracting elements
  • DSLR photography (original): It depends, for dust protection only
  • DSLR photography (astro modified): It depends, for dust protection only
  • DSLR photography (MC modified): Very good, if used with optics which contain refracting elements
  • Webcam / Video (Planets): Very good, if used with optics which contain refracting elements
  • Webcam / Video (Deep Sky): Very good, if used with optics which contain refracting elements

Technical Data

  • 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
