Astronomik ProPlanet 642 IR Filter - Nikon XL Full Frame Clip


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.

The P642 IR-Pass Filter offers a 200 nm spectral window between 642 nm and 842 nm. As opposed to the other two Astronomik ProPlanet filters, the P642 blocks the longer infrared. Astronomik is now providing users with three separate options for their IR-imaging needs, this P642 filter as well as their other two ProPlanet filters, the 742 and 807. For best imaging, the ProPlanet 642 will frequently be the ideal choice.

Daylight IR-Imaging:

  • Images feature high contrast and superior color presentation
  • Transparent images with "wood effect"
  • No hot spot in the longer IR
  • Short exposure times, nearly identical to regular VIS-imaging
  • Optimally equipped for infrared videos

High Resolution Lunar & Planetary Imaging:

  • Short exposure times
  • Effective decrease in seeing
  • Optimized contrast
  • Longer IR obstruction removes ghosting and allows peak sharpness


Deep-Sky Astrophotography of H-Alpha Regions:

  • Best H-alpha line transmission at 656 nm
  • FWHM of approximately 40 nm with DSLR cameras that have been astro-modified
  • Spectacular contrast in moonlight or with severe light pollution
  • Reasonably priced filter for amateur H-alpha imagers
  • Easy focusing facilitated by the combination of camera display and LiveView


Technical Specifications

  • More than 96% transmission for the 642 nm to 842 nm wavelength range
