Astronomik ProPlanet 642 IR-Pass SCT Rear Cell Filter




The most recent addition to the Astronomik ProPlanet IR-pass filter family, the ProPlanet 642 BP facilitates an extensive array of applications for daytime IR photography, high resolution Moon and planetary imaging, and taking awe-inspiring photos of deep sky targets in the H-Alpha portion of the spectrum when used for astro-imaging.



This filter provides a 200 nm spectral window from 642 nm to 842 nm. Unlike Astronomik's other two ProPlanet filters, the P642 blocks the longer infrared. Along with the ProPlanet 742 and 807 filters, Astronomik now gives you three choices for your IR-imaging needs. The ProPlanet 642 will frequently be the correct choice for optimal imaging.



Daylight IR-Imaging:



  • Images have high contrast and superb color presentation
  • Transparent images have "wood effect"
  • No hot spot in the longer IR
  • Short exposure times analogous to regular VIS-imaging
  • Works best for infrared videos




High Resolution Lunar & Planetary Imaging:



  • Short exposure times
  • Effective reduction in seeing
  • Optimized contrast
  • Longer IR blocking eliminates ghosting and enables peak sharpness




Deep-Sky Astrophotography of H-Alpha Regions:



  • Excellent 656 nm H-Alpha line transmission
  • Close to 40 nm FWHM with DSLR cameras that have been astro-modified
  • Amazing contrast despite moonlight or severe light pollution
  • Modest filter price favorable for casual H-Alpha imagers
  • Easy focusing facilitated by the combination of camera display and LiveView




Technical Specifications




  • Transmission for wavelengths between 642 nm and 842 nm is over 96%
  • Wavelengths from 350 nm to 630 nm are obstructed
  • Parfocal with all other filters carried by Astronomik
  • 1 mm glass thickness
  • Fully protected from the impacts of scratching, aging, and high humidity
  • Diffraction limited, this filter will not lower the optical performance level of your telescope
  • Astronomik filters are delivered with a durable, high quality plastic storage container
