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 the light of wavelengths longer then 742 nm to pass. This results in a big improvement in images of planets and the Moon. Images are more steady than the image in visible light, with nearly identical required exposure times. The Astronomik ProPlanet IR 742 Filter is also parfocal with other Astronomik filters.

Along with video capture and CCD astrophotography, this P742 IR filter also facilitates gorgeous terrestrial photography. When this P742 filter 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.
