Quick Summary

Celestial photography, also known as astrophotography, is the practice of photographing astronomical objects and events. This technique allows for the recording of celestial bodies that are too faint to be seen with the naked eye by accumulating light over long exposure periods.12

Historically, photography was the primary method for detecting many faint celestial objects before the advent of radio telescopes. Astronomical cameras are typically attached to powerful telescopes mounted on precision, clock-driven systems to counteract Earth's rotation during exposures that can last for hours.2

Modern astrophotography utilizes advanced detectors like charge-coupled devices (CCDs), which are significantly more sensitive than traditional photographic film and can capture a wider range of wavelengths. These technologies enable detailed imaging and spectral analysis of stars, nebulae, and other cosmic phenomena, revealing information about their composition and physical conditions.342

photometry
The introduction of photography provided the first nonsubjective means of measuring the brightness of stars. The fact that photographic plates are sensitive to violet and ultraviolet radiation, rather than to the green and yellow wavelengths to which the eye is most sensitive, led to the establishment of two…
