  • Description

    Baader Planetarium delivers the latest tool in the planetary imager's bag of tricks. The Baader IR-Pass filter blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). By combining a luminance image taken with the IR-Pass filter, along with RGB frames, overall image sharpness is significantly enhanced. Some of the world's best amateur planetary images have been taken with this technique.
    The IR-Pass filter shares the same outstanding features as all the other Baader filters. High optical quality, Striae-free substrate and high efficiency multicoatings result in the sharpest and highest contrast image possible.
