More About Astronomik ProPlanet 742 IR-Pass Filters

Ideal for video imaging of 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.

By simultaneously allowing only light from wavelengths longer than 742 nm to pass while completely suppressing the visible area of the spectrum, the Astronomik ProPlanet IR 742 Filter greatly enhances images of the Moon and planets. Images are more steady compared to the image in visible light, with close to the same necessary exposure times. Additionally, the ProPlanet IR 742 is parfocal with all other filters made by Astronomik.

Video capture and CCD 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 P742 filter 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.

Astronomik Pentax K-1 Clip Filter System

Compatible with Pentax K1 and K1 Mk II digital SLR cameras, this Pentax K1 clip filter is the newest member of the Astronomik clip filter family. Does not support camera models with APS-C sensors! Astronomik clip filters are designed to be used with traditional camera lenses for use with telescopes.

Transmission Specifications

  • 96+% transmission for wavelengths of 742 nm to 1100 nm
  • Blocks unnecessary wavelengths from 350 nm to 730 nm
