ASTRO 310: Observational Astronomy
Prof. Sylvain Veilleux (CSS 0223, veilleux{at}astro.umd.edu)
TA. Stacy Teng (CSS 0202, stacyt{at}astro.umd.edu)

Course Description: Introduction to current optical observational techniques, with brief coverage of infrared, ultraviolet, and X-ray techniques. Statistics, geometrical optics, telescopes, effects of the atmosphere, spectroscopic instruments, and detectors. Practical work at the observatory using a CCD camera. Some nighttime observing sessions.
