Hutech/IDAS planetary imaging filters are specialized filters designed with tuned passbands intended to enhance features of specific planetary targets. Note that these filter bandpasses are at (or beyond) the edges of the visual spectrum. The camera and optical imaging components must be designed for proper operation at these wavelengths.
This filter is used for imaging vapor and clouds on Mars and Venus as well as for imaging biological subjects. The UV bandpass design enhances in-band contrast by aggressively eliminating out-of-band light:
Available in 31.7mm(M28.6)
This filter is used for imaging Venus (increases contrast for lower atmosphere cloud structures).
This filter is used to image Mars. It enhances the visibility of atmospheric water vapor clouds
