Baader Planetarium IR Pass Telescope Filter
Best optical enhancement for serious planetary astrophotographers.
This filter is designed for planetary imaging, effectively blocking wavelengths below 670 nm. By doing so, it minimizes atmospheric distortions, commonly known as seeing, allowing for sharper and higher-contrast images. Combining luminance images captured with this filter with RGB frames can significantly enhance overall image sharpness.
