Public perception often mistakenly assumes that telescope images reflect how the human eye sees celestial objects. However, astronomers utilize advanced camera technology that interprets light differently than human vision. Cameras and our retinas operate on distinct principles: human vision relies on rods and cones, while cameras use pixels to capture photons. Consequently, images from the Hubble or JWST do not emulate the exact colors or visibility but rather provide approximations that factor in technological limitations and artistic interpretation. Understanding this nuance enriches our appreciation of astrophotography.
Two kinds of cells in your retinas, called rods and cones, are the basis of human vision. Rods can't detect color but are good at registering low levels of light.
No photograph, including ones you take with your smartphone, can perfectly replicate what your eye sees. The best our tech can do is approximate what you see.
