Although optical telescopes are the type most commonly used for stargazing and amateur astronomy, lots of astronomical research is done on telescopes that look at other wavelengths of light. Each of these wavelength ranges shows us something unique about the universe and allows us to view events and objects that can't be seen with human eyes.
Yet binoculars reveal many sights that most people think require a telescope â including craters, mountains, and plains on the Moon, planets and their satellites, the brightest asteroids at favorable times, the occasional comet, countless double and variable stars, dozens of star clusters, and some nebulae and galaxies.
