N.B. As of this writing (April 2003) cameras and camera software are still evolving as we gain experience in actual operation. The following notes may not include the latest changes.

New guide cameras have been, or soon will be, introduced at the Shane 3-meter prime focus, cassegrain, and coude, the CAT, and the Nickel 1-m. Each system consists of a camera containing a thermoelectrically cooled LBL high-resistivity CCD, a camera power supply, a Linux-based computer, control software, and a GUI.

Hardware is identical across installations, but software varies, depending on telescope, focus, and instrument. Software is started according to the table below:

from x-term
command line
from Gnome
window manager
Couderedeye2romeguidecoude Click on
Cass redeye1romeguidecass
Cass w/Geminiredeye1romeguidegemini
Primeredeye1romenot yet installed

For 3-m observing, the guider is started from--and the GUI displayed on--the telescope operator's console ( For CAT and 1-meter operation, the observer uses the consoles for redeye2 and redeye3, respectively.

If the terminal you use for guiding is running the Gnome window manager, you may start the guide software and GUI by clicking on the guider icon at the bottom of the screen. (Rome displays several guide icons for 3-meter guiding. Select the one appropriate to the focus and instrument.) If your window manager is fvwm, start the guide software and GUI from the x-terminal command line, using the appropriate command listed in the table above.

Starting the guide software will cause the several elements of the GUI to be displayed. This may take as long as 10-15 seconds. Don't try to interact with the GUI until startup has completed. You can follow the progress of the startup in the text-only log window.

The completed screen will look something like the one illustrated below. The parts of the GUI are divided according to function: camera control, guider control and monitoring, image display and control, and the log window. Only one copy of the guider GUI can be run for any given guide camera, but near-simultaneous copies of the image display and image control windows can be run from any computer on which the Guider Copy program has been installed, allowing, for example, a 3-meter observer to monitor acquisition and guiding being performed by the telescope operator.
