Opening the Observatory

Before starting, it is strongly recommended that you open up an xterm (change size to be as long a possible) to display the output of the observatory server tserver by typing:

show tserver

Keep this window open to monitor the status of the telescope and all the devices. Then in a second xterm type:

openup

This script will open the slit, check that the devices have been homed, open the telescope mirror and generally prepare for observations. When this command is finished type:

keepopen maxtime=3600

or whatever number of seconds you plan to observe. Leave this program running to keep the slit open. Shrink the window to a small size.

Finally open a third command window to type your commands.
