More About the Astronomik 36 mm ProPlanet IR 742 Filter
For capturing stunning images 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 P742 filter offers tremendous enhancement of lunar and planetary images by simultaneously obstructing visible light while permitting only emissions from wavelengths longer than 742 nm to be transmitted through to the image. Compared to the image in visible light, this image is more steady with exposure times that are nearly identical. Furthermore, like all filters offered by Astronomik, the ProPlanet IR 742 is parfocal with all other Astronomik filters.
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.
- 96%+ transmission for wavelengths between 742 nm and 1100 nm
- Blocks undesired wavelengths from 350 nm to 730 nm
