Astronomik ProPlanet 742 IR-Pass EOS XT Clip Filter - P742-EOS-XT

SKU: ASF-P742-EOS-XT

Astronomik ProPlanet 742 IR-Pass Filter - XT EOS Clip

  • Mounted in an XT clip filter format, this Astronomik ProPlanet 742 IR-Pass Filter is ideally suited for both CCD astro-imaging and webcam or video planetary capture
  • Astronomik XT EOS APS-C clip filters enhance image quality by providing magnificent star images to the corners of the view field, allowing users to fully benefit from Astronomik clip filters even when capturing ultra wide angle photos with short focal length instruments
  • Created to the highest technical standards for the high optical performance you want and need for imaging planets with approximately 5" to 8" aperture telescopes
  • This filter allows only Infrared light with wavelengths of more than 742 nm to pass through
  • Since images are created from IR light, atmospheric turbulence will have less of an affect on planetary images
  • Multi-layer coatings on all Astronomik filters protect them well against the effects of scratching, aging, and high humidity
  • Made in Germany, a country recognized for their high optical quality!


More About Astronomik ProPlanet 742 IR-Pass Filters

For capturing stunning images and video of the Moon and planets, specifically Mars, with telescopes that have apertures of 6" (150 mm) or higher, the Astronomik ProPlanet 742 IR-Pass Filter is the optimal choice. Only infrared light with wavelengths over 742 nm is allowed to pass through. Seeing effects are substantially reduced in this area of the spectrum versus the visual spectrum of the human eye. This results in images that are significantly sharper than what could typically be achieved from your device and location. Another advantage of the ProPlanet 742 IR is that it still facilitates a dark sky background even in late dawn. This allows lunar and planetary photography to continue even at daybreak.

The Astronomik ProPlanet 742 cuts off the visible part of the spectrum and allows only the light of wavelengths longer then 742 nm to pass. This results in significant improvements in lunar and planetary image results. Images are more steady than the image in visible light, with nearly identical required exposure times. The Astronomik ProPlanet 742 IR Filter is also parfocal with other Astronomik filters.

Along with astrophotography, this P742 IR filter also facilitates gorgeous terrestrial photography. When the XT EOS P742 Clip filter model is used in an MC modified Digital SLR camera, you'll be able to achieve exceptional results for nature imaging. This filter blocks the area of the spectrum where chlorophyll appears green, and displays its high reflectiveness in the near infrared. Photographing trees in the spring and summer months under blue skies gives you amazing images with trees and clouds that appear white ahead of a almost black background.

Astronomik XT Clip Filter System

Constructed using black anodized aluminum, this proprietary Clip-Filter system from Astronomik is produced on the most advanced, state-of-the-art machinery. Astronomik Clip Filters have long been a well-received accessory among astrophotographers. With these Astronomik XT clip filters, capturing extremely wide-angle images is now possible without compromising image quality at the corners. This is due to an ultra-thin carrier substrate of only 0.3 mm. Astronomik XT filters contain the same multi-layer coating technology as all other Astronomik filters, despite this ultra-thin glass. They offer full resistance to the effects of scratching, aging, and high humidity.

Transmission Specifications

  • Transmits over 96% of wavelengths between 742 nm and 1100 nm
  • Blocks undesirable 350 nm to 730 nm wavelengths
