W. M. Keck Observatory
LRIS slitmask
A slitmask for the Low Resolution Imaging Spectrometer at Keck. A lot of my time in grad school was spent designing these slitmasks. Each of the slits corresponded to a (candidate) high-redshift galaxy whose spectrum we wanted to collect.
Keck logo window
Window in the rear of the visitors' center, facing the ops rooms. When observing, we would spend the night in the ops rooms, directing the observations and reviewing the data.
NIRC
The Keck near-infrared camera. I used this instrument in grad school, and now it's a museum piece.
