The Baader Planetarium company has introduced the latest tool from the collection of "hat tricks" for astrophotographers. The Baader IR-Pass filter blocks waves below 685 nm. At longer lengths, planetary images are much less distorted by interference from atmospheric fronts ( seeing ). By combining the luminance image made by the IR-Pass filter with RGB frames, we achieve a significant improvement in the overall sharpness of the image. Many of the world's best amateur images of planetary nebulae have been made using this technique.

The IR-Pass filter also has other outstanding features that distinguish all other Baader filters. High optical quality, substrate free from lines close together, and high-performance coatings give images as sharp and contrasting as possible.
