Astronomik ProPlanet 742 IR-Pass Filter - T-Mount




  • This Astronomik ProPlanet 742 IR Filter is designed specifically for astrophotography of the planets and is mounted in a 2" machined cell
  • Made with regards to the highest technical guidelines to provide the optical performance required for planetary imaging with telescopes featuring apertures in the 5" to 8" range
  • With this filter, only infrared emissions with wavelengths of more than 742 nm are allowed to be transmitted
  • Atmospheric turbulence will not afflict planetary images since they are formed from IR light
  • Multi-layer coatings on all Astronomik filters protect them well against the effects of scratching, aging, and high humidity
  • German-made for supreme quality optics!




More About the Astronomik T-Thread Mounted ProPlanet IR 742 Filter




Ideal for imaging the Moon and planets, particularly Mars, with 6" (150 mm) or more aperture telescopes, Astronomik ProPlanet 742 IR-Pass filters only permit the transmittance of infrared light with wavelengths of more than 742 nm. In this part of the spectrum, seeing effects are substantially lower than in the visible spectrum of the human eye. This enables considerably sharper images than can be typically obtained from your device and location. Another benefit of the ProPlanet 742 IR is the dark sky background of advanced dawn, enabling lunar and planetary photography even at daybreak.



While the P742 filter is allowing light from wavelengths over 742 nm to pass through, it is also fully blocking the visible portion of the spectrum at the same time. This optimizes both lunar and planetary images considerably. Steadiness improves over the image taken in visible light, with nearly identical exposure times needed. And, like all Astronomik filters, the ProPlanet IR 742 is parfocal with all other filters carried by Astronomik.



Astro-imaging of the Moon and planets is not the P742 IR filter's only purpose as it also enables incredible terrestrial photography results. If the EOS-Clip P742 filter model is employed in an MC modified DSLR camera, you'll obtain excellent results imaging nature. It eliminates the portion of the spectrum where chlorophyll looks green, and shows its high near infrared reflectiveness. When taking photographs of trees in the spring and summer under clear skies, the resulting image is striking. Trees and clouds are displayed as white in front of an almost completely dark background.



Transmission Specifications




  • 96%+ transmission for wavelengths between 742 nm and 1100 nm
  • Blocks undesired wavelengths from 350 nm to 730 nm
