Astronomers usually measure the flux of an object by collecting light with a telescope, sending it through a known filter, and then determining the power. ... But astronomers usually give their photometric results in terms of magnitudes. ... Astronomers define an absolute magnitude that is independent of the distance of a star and only depends on the intrinsic properties of the object: the absolute magnitude is the magnitude the star would have if it were 10 parsecs away from the Earth. ...

... Like the Lynxx and the ST-4, this camera has a preferred orientation with the telescope (see figure 4). ... Before taking images, the camera and the telescope have to be calibrated. ... This is the normal CCD camera image mode. The second method is the track and accumulate mode. In this mode, the camera takes several short images, and then adds them together to give an image that is comparable to the same total time image as taken by the grab function. ...

... A faint, dusty rose of the northern sky, emission nebula IC 410 lies about 12,000 light-years away in the constellation Auriga. The cloud of glowing hydrogen gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. ... These "tadpoles" (seen just below center) are regions of denser, cooler gas, and more slowly resist the erosive radiation from the hot stars. ...

... Bad Astronomy . ... Radio . ... Bitesize Astronomy . ... Think of a telescope as a bucket that collects light. ... So over the years, telescope makers have focused on making telescopes bigger and bigger. ... For radio telescopes, however, the size limit is much bigger. Many astronomical objects emit radio waves, and as it happens telescopes built to detect radio don't have the same stringent smoothness criteria optical telescopes do. ... But radio telescopes can get even bigger. ...

Next: The Focal Plane Instruments Up: No Title Previous: The X-ray Optics . CXO has two focal plane instruments - the High-Resolution Camera (HRC) and the Advanced CCD Imaging Spectrometer (ACIS). Each of these instruments, in turn, has two detectors, one optimized for direct imaging of x rays that pass through the optics and the other optimized for imaging x rays that are dispersed by the objective transmission gratings when the latter are commanded into place directly behind the HRMA. ...
