This is particularly true if you're looking at pictures of nebulas. The hydrogen alpha light is in the infrared and for humans is color mapped to red.

Cameras are sold with the capability of capturing the hydrogen alpha light. Like the Nikon 810A which is a Nikon 810 but with the IR filter removed.
