Search for: Introduction to Astronomical Instruments. Each chemical element has its own "signature" spectral pattern, so it's possible to analyze the composition of a star from many thousands of light-years away provided astronomers can collect its light. While visible objects such as stars and galaxies emit radio waves as well as light waves, others can only be detected by radio telescopes. It might be outdated or ideologically biased. Although radio telescopes vary, based on its shape and size, and the kind of … Astronomical Instruments . Optical Telescopes -- The purpose of a telescope is to collect light and then to have the image magnified. The Meade LX200 "Classic" computer control system permitted the telescope to be mounted in an altazimuth orientation, while motors, directed by an internal microprocessor, on both telescope axes followed astronomical objects with extreme precision.

The overall goal is to fully understand the physical principles and performance of astronomical instruments and to contribute to the development of new instrumentation technologies. = 휶? = 휶? Astronomy. The first category might includeall of the instruments which are used in the actualprocess of observing celestial objects. Compared to a telescope, binoculars for astronomy actually have certain advantages. The first detector used for astronomical observations was the human eye, but it suffers from being connected to an imperfect recording and retrieving device—the human brain. Other instruments can be placed in the focal plane for various purposes, e.g., a photo-electric cell to measure the luminosity, the slit of a spectrograph to analyse the light, or a thermo-couple to measure temperature. He used his "three-powered spyglass" to discover the four main moons of Jupiter as well as numerous previously unknown features of the moon.
