Amateur astronomyUploader: JoJot 4 month ago Subscribe 9
The Low Resolution Imaging Spectrometer LRIS is a faint-light instrument capable of taking spectra and images of the most distant known objects in the universe. In particular, this applies where large numbers of amateur astronomers with small telescopes are more effective than the relatively small number of large telescopes that are available to professional astronomers. Because CCD imagers are linear, image processing may be used to subtract away the effects of light pollution, which has increased the popularity of astrophotography in urban areas. Collectively, amateur astronomers observe a variety of celestial objects and phenomena. With these computer-driven telescopes, the user typically enters the name of the item of interest and the mechanics of the telescope point the telescope towards that item automatically.
