== Autoguiding ==
As of February 2021, there is a web browser interface to the backend autoguider control GUI, so users no longer need to access the backend ([[#Backup autoguiding procedure|unless you have problems]]). Note that the original autoguider software does need to be running on ioserver1 in order to operate the guider, but you shouldn't need to interact with it directly. The procedure for autoguiding via the browser is described below.
Open a web browser and navigate to:
10.2.2.32:5001
'''Make sure that there is only ever one autoguider window open at a time, or you will have problems.'''
The autoguider control interface looks like this:
<br clear=all>
The autoguider camera image is displayed on the top right, with the finderchart image below. There will be a green "Online" indicator at the top left if all is well; if it's red ("Offline") the autoguider control software might not be running on ioserver1. If it looks ok, continue reading this section, otherwise - and if you run into trouble with any of the steps below - skip to the [[#Backup autoguiding procedure|next section]]call a technician.
To acquire a guide star, do the following:
# Click "Stop Continuous" to stop exposing.
# Click "INITIALISE" to return the XY-slides to the home position.
# In Close the terminal running the web server, press CTRL-C to kill the processbrowser window.
== Shutdown recipes ==
# Click the '''SHUTDOWN''' button on the bottom right of the TCS screen. This will close the mirror & baffle covers, close the dome shutters, and park the telescope and dome. A blue progress circle will rotate on the button while all the commands are executed; it will disappear once the shutdown procedure is complete.
# Turn on the slew lights on the "Advanced" tab and check on the Mobotix webcam that telescope and dome are closed and parkedand closed.
# On the central panel of the TCS "Controls" tab, check for grey or orange indicators showing the status of each subsystem: telescope Tracking = Off (grey); Mirror covers = Closed (orange); Dome (orange) Tracking = Off (grey) and Shutters = Closed (orange) [the arc indicating the shutters on the schematic will also turn red and settle in the West].
# On the left-hand panel of the Controls tab, there should be a message in orange stating "Unpark telescope to slew", indicating that the telescope is parked.
# If any of the above is not in the correct state, you can rectify it using the relevant buttons on the Advanced tab.
# '''Logout''' of the TCS and close the webcam browser windowswindow.# Stop the autoguider exposures and , initialise the XY slidesand close the autoguider browser window.# Close the webcam browser windows.
# Make sure the instrument (Mookodi or Sibonise) is not exposing and follow the relevant instrument shutdown procedure.

== Troubleshooting ==
The table below describes some problems you might encounter. Some can be tackled by the observer (see column 4). If the suggested steps to be followed by an observer fail, please call a technician.
{| class="wikitable" border="1"
| Mechanical or electronic standby.
|-
| The telescope spontaneously shut down (mirror covers closed, dome closed, telescope parked).| The facility was shutdown by the LCU, either due to bad weather or a loss of connection to the TCS.| Check the weather: if it's bad you must leave the telescope closed. Check the TCS: if there is a message stating that the connection has been lost, reload the page. If the weather is good, press Startup and resume observing.| Observer|-| The dome didn't open on startup, or closed by itself and won't reopen.
| There may be a dome comms problem.
| Call a technician to remedy.
