ProPlanet IR Pass Filters

 

Astronomik’s ProPlanet 642 BP or bandpass clip filters are ideally suited for infrared imaging during daylight hours with modified DSLR cameras. Normal, unmodified DSLRs do have a built-in infrared blocking filter in place as the sensors alone are sensitive up to 1100nm. If this internal filter is removed, the camera can be used for the thrilling field of infrared imaging once a ProPlanet 642 filter is introduced into the lightpath.

The ProPlanet IR 742 is ideal for imaging the Moon and planets, with telescopes 6” and larger (150mm) when the seeing is poor. This filter allows infrared light with wavelengths of more than 742 nm to pass. In this wavelength range, the effects of seeing are significantly lower than in the visible spectrum of the human eye, allowing much sharper images than are usually obtained from your imaging setup. 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 during daylight.

The Astronomik ProPlanet IR 807 cuts off the visible part of the spectrum and allows the light of wavelengths longer than 807nm to pass. The part of the spectrum that is most sensitive to poor seeing and great improvements can be realized when imaging the Moon and planets. This filter is ideal for imaging the Moon and planets, with telescopes 10” and larger (250mm) when the seeing is poor.
