Astronomik ProPlanet 807 IR-Pass Filter

Astronomik's ProPlanet 807 IR Filter works in conjunction with the Astronomik P742 filter for Moon and planet photography when using large telescopes with apertures of 10" (250 mm) or more and seeing conditions are weak. In addition, this filter can be used in combination with converted DSLR cameras, CCD cameras, and Webcams. Negative viewing effects are sharply reduced. The P807 filter represents your entry point to heretofore uncharted territory in lunar and planetary astrophotography.

With this filter, the only light permitted to pass through is light from wavelengths of 807 nm or longer. Adverse seeing effects are reduced considerably in this range versus the visual spectrum of the human eye. This greatly enhances image sharpness and steadiness compared to what your device and location could typically realize. Moreover, the ProPlanet 807 delivers a dark sky background well into dawn so you can keep imaging the Moon and planets even as the Sun is coming up.
