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.
