Masters of the 3.5-m

APO 3.5-m Control Room
Graduate students George Privon and David Whelan are captured here in the control room of the Apache Point Observatory (APO) 3.5-m telescope during their observing run in November 2007. George, David, and astronomer Trinh Thuan were trying to constrian primordial Helium abundances using spectroscopy of emission-line galaxies. The APO 3.5-m is one of many telescope facilities for which UVa's Astronomy Department has direct access.
