Astronomik ProPlanet IR Pass Filter

This filter blocks visible light and only allows infrared wavelengths above 807 nanometers to reach your sensor. By focusing on these longer wavelengths, it effectively cuts through atmospheric turbulence, which helps stabilize the image and reveal finer details on planets like Mars or Jupiter.

Infrared light is less sensitive than visible light, so it requires a significant amount of light-gathering power to produce a bright, usable image. Smaller telescopes often struggle to capture enough signal at these wavelengths, leading to underexposed or noisy results.

Yes, it is excellent for daytime imaging of bright celestial objects. Because it blocks the visible spectrum, it significantly darkens the blue sky background, creating a higher contrast environment for capturing planets like Venus or Mercury during the day.

This filter uses a standard 1.25-inch connection, making it compatible with most common eyepieces and camera adapters. It is best suited for reflector and Schmidt-Cassegrain telescopes, provided your specific camera sensor is sensitive to infrared light.

Unlike color filters that isolate specific visible wavelengths, this filter completely eliminates the visible spectrum. It is a specialized tool designed for specific conditions, such as poor atmospheric seeing or high-contrast planetary imaging, rather than general-purpose observation.
