  • Astronomik Planet IR Pro 742 Filter - 1.25-inch Mounted

    The Astronomik ProPlanet 742 is the ideal filters for the reception of the moon and planets, notably Mars, with telescopes from 6-inch (150mm) aperture.

    The planet IR Pro 742 only allows infrared light with wavelengths of more than 742nm to pass. In this wavelength range the effects of seeing are significantly lower than in the visible spectrum of the human eye. This allows much sharper images than are usually obtained from your device and location. Another advantage is that the sky background of advanced dawn is dark and so the filter even allows photography of the planets and the moon at daylight.

    The Astronomik ProPlanet 742 cuts off the visible part of the spectrum and allows the light of wavelengths longer then 742nm to pass. Due to this behavior the part of the spectrum that is most sensitive to bad seeing is rejected. This approach does a big improvement to the imaging of planets and the moon. The image is more steady than the image in the visible light with nearly identical exposure times.

    Besides astrophotography the filter allows you to get stunning results in nature photography. If an EOS-Clip Filter is used in an MC modified DSLR you get tremendous results imaging the flora. The filter cuts off the part of the spectrum where Chlorophyll looks green and shows its high reflectivity in the near infrared. If trees are photographed in spring and summer under blue skies you get stunning images with white trees and clouds in front of a near black background. The Astronomik ProPlanet 742 darkens the background during twilight and allows imaging of bright planets, stars and comets by day. It also promotes imaging of young stars in dust clouds and stellar nurseries. (When the seeing is very bad and the instrument is 10-inch (250mm) or larger, the Astronomik ProPlanet 807 may be the better choice.)

    Planetary IR Filter

    I only have used this once for Saturn & Mars with my ASI 290MC. The filter worked well with natural looking colors.

    Works on Mars

    I got my first decent photo of Mars this year using the Astronomik IR Pro 742. Didn't need an IR filter in prior years, but it was a necessity this year between my seeing and the Martian dust storms.
