In addition to the graphical user interface, the new telescope also includes a "feed emulator program" which allows you to run the telescope by typing in the same commands used in the old Venix operating system. You may choose to use either the graphical interface or the command line interface.
After you login, the computer system will automatically load the telescope control system and open two windows, one for telescope control and one for access to the "star caches" or coordinate files. These two basic windows should be open throughout the night, but additional windows will pop up as needed. The screen layout includes a third window for entering typed commands.
To work in a window, move the mouse's pointer to within that window. In the window are "buttons," boxes for displaying information, and fields for entering information. The mouse is used to control most of the action on the screen. Generally, the left button on the mouse is used to "push" a button on the screen, and the right button is used to access and select menus. To "push" a button, move the mouse's pointer onto that button and click the left (select) button on the mouse. To enter information into the program (e.g. the wavelength setting for the grating) move the mouse's pointer to the line for the information you want to enter, and then type in the appropriate number or character string. If the task calls for entering several fields (e.g. adding a new star to a star cache) the carriage return will automatically move you to the next field. Note the most windows contain a "close," "cancel," "quit," "exit," "enter", or "ok" button to exit and close that window.
With that brief introduction, choose where you want to go next.
