Astronomical optics collect electromagnetic radiation and redirect it to form images or feed instruments. Understanding image formation is necessary for choosing camera pixel size, focal length, magnification, field of view, and focus position and for diagnosing aberrations such as coma, astigmatism, or chromatic error.

Aperture and focal length control different aspects of a telescope's performance. Astronomers match aperture, focal length, seeing, and pixel size so data are neither undersampled nor wastefully oversampled.

Refracting telescopes use lenses to bend light to a focus, while reflecting telescopes use curved mirrors. Small refractors are robust and provide high-contrast views, while large research observatories use reflective designs to achieve large apertures and flexible instrument placement.

Modern astronomy depends on detectors that count or measure incoming radiation and instruments that separate that radiation by wavelength. Imaging reveals morphology and brightness, while spectroscopy reveals composition, temperature, density, magnetic fields, and line-of-sight motion.

Adaptive optics and interferometry are two different techniques for improving angular detail. Adaptive optics is powerful for near-infrared and visible ground-based imaging of compact targets, while interferometry enables extremely high-resolution radio, millimeter, and selected optical observations.
