... Charge Coupled Devices (CCD) are currently by far the most widely used type of detector in astronomy. ... After a brief introduction to the VLT Control System, the VLT CCD Detectors Control Software is presented. The VLT Control System is a distributed system consisting of a set of UNIX Workstations, dedicated to high level operations, such as coordination of sub-system activities and interface to the users, and VME-based Local Control Units (LCU), dedicated to the control of sub-systems hardware. ...

The Discovery of the Galilean Satellites . ... Probably the most significent contribution that Galileo Galilei made to science was the discovery of the four satellites around Jupiter that are now named in his honor. Galileo first observed the moons of Jupiter on January 7, 1610 through a homemade telescope. He originally thought he saw three stars near Jupiter, strung out in a line through the planet. ...

In 1990, Duncan Steel, then of the Uni. of Adelaide, commenced the Anglo-Australian Near-Earth Asteroid Survey. This project took advantage of the photographic work being undertaken at the 1.2-m U.K. Schmidt Telescope of the Anglo-Australian Observatory. Since the U.K. Schmidt had commenced its photographic sky surveys in 1973, many comets had been found, but few NEAs. ... The status of the AANEAS and other U. K. Schmidt NEA discoveries can be found here. ... Siding Spring Survey Main Page . ...

Large sunspots were occasionally seen far in the past without any instruments, when the sun was dimmed by thick haze, but not much was remembered of those observations. ... Sunspot Cycle (1850 - 1975) . One who was greatly influenced by Schwabe's discovery was an English gentleman of independent means, Richard Christopher Carrington , who devoted himself to the study of sunspots. ... Carrington had seen a flare, of the rare variety that is visible in white light (only about 50 are known). ...

... 400mm f/2.8 Nikor lens: images the sky on the entrance slit. ... The optical system maintains image quality along the slit length so that each row of the image is a spectrum of that spatially selected region of the sky. 180mm f/2.8 Nikor lens: collimates the light from the slit. ... The auxiliary optical platform on WISPI now accomodates a short focal lens and a guiding/imaging video system that may use sub-pixel corrections to provide feedback to the tracking drive motors. ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...
