Image 1 Image 2 and Image 3 are the control screens for the DEIMOS spectrograph

Image 4 the DEIMOS controls and telescope controls, although we did not observe due to the weather DEIMOS was calibrated early in the evening using the artificial lighting in the observatory. At the end of the night I got to shut DEIMOS down, reading the procedure off of one screen and applying the commands to another.

Image 5 This is Prof Chuck Steidel from Caltech in the Keck I remote control room, Chuck kindly invited me along for a third nights observing with him. This night was clear as, all night with 0.6 arcsecond seeing. In this image Keck I is online and data is streaming in. The screen in the top left shows the Tech assistant at the summit, she also sees us. The three screens in front of Chuck is where it is all happening.

The screen on the left shows the configuration of Keck I diagrammatically, with the beam splitter sending data to an imager or the spectrograph. Top right of this screen shows the star field that the guiding camera is looking at, there is a box drawn around the star that is being used to track with.

The central screen shows the Quasar at 10 billion l/y that Chuck is imaging.
The screen on the right shows the mask that Chuck is using on the spectrograph. He was hoping to use the continuum of the Quasar to detect foreground Lyman Alpha clouds.

Image 6 as for previous image, note in the central and right hand screens the blue bar filling horizontally across the screen, this indicates how far through the 30 min integrations of the red and blue wavelength we are.

Image 7 The central and right hand screens now show the results of the first 30 min integrations with the spectra shown horizontally in the central screen and vertically in the right hand screen.

Image 8 This is the telescope control screen, note the three green lights in the lower left quarter of the screen. The previous two nights on Keck II with Duncan's team those lights were red all night, which meant the dome could not be opened.
