/* Autoguiding */
# Check that "Error = 0". If "Error = 1" click "RESET".
# Click "INITIALISE" to initialise the XY slides. Confirmation of a successful initialisation is indicated with "Initialised = 1".
# From the dropdown menu under "GOTO GS", Select Slide 0 if using SHOCMookodi, or Slide 1 for Sibonise (each Nasmyth port has its own autoguider). '''Make sure the camera is not exposing when switching slides.'''
# Enter the RA and Dec of your target on the two lines below "Fetch DSS image". Use space delimiters, not colons.
# '''Slew the telescope to the target using the TCS and make sure it is tracking before pressing the "Fetch DSS image" button'''. This is important because the autoguider software needs to know the rotator angle relative to the sky in order to load the catalogue image in the correct orientation.
# A catalogue image of your field will load in the bottom right. Click on a fairly bright star in the top half of the image to use as a guide star. The closer to the top of the image the better, to avoid vignetting the SHOC Mookodi field (central) with the Lodestar camera pickoff arm.
# Click "GOTO GS" to the left of the finderchart. You will see the XY slide coordinates updating and the status "Moving = 1".
# In the upper-left "Exposure Control" section, enter an exposure time in milliseconds (e.g. 2000) and click "Start Continuous".
'''To start guiding''':
# On the main autoguider GUI, if using SHOC Mookodi select Slide 0; or Slide 1 for Sibonise.
# If the status of any of the error codes (Err, XLL, XUL, YLL or YUL) is 1, click RESET, then INITIALISE. "FAKE" should always be a green "Fake is OFF" button while guiding - this is a test function for engineering purposes.
# To start continuous exposures with the autoguider Lodestar camera, enter a number (~2 seconds) in the box on the right, and click CONTINUOUS. Binning should be set to 2x2. To get a workable look-up table, on the left-hand side of the main autoguider GUI, move the uppermost vertical slider ~1/6 of the way from the bottom. Leave the other two sliders in their default positions (lower vertical slider halfway up; lower horizontal slider all the way to the left; upper horizontal slider all the way to the right).
# Enter the target coordinates (using spaces as delimiters, e.g. 12 34 56 -76 54 32) in the separate GS_FC window and click "Set".
# Check that a finder chart loads showing your field. Guide stars are to be selected from outside the green box in the finder chart image. When North is Up in the SHOCMookodi/Sibonise image, click on a star in the upper half of the image to use as a guide star.<!--, with X<20000 and Y<15000. As Y approaches 10000 increases it begins to vignette the SHOC Mookodi field, so try to choose a guide star at low Y.-->
# On the XY Slide Control section of the main GUI, click "Goto GS". This will send the XY slides to the position you clicked on the finder chart. <!--If it doesn't, read the coordinates of the guide star off the image and enter them manually; when the position is reached click "Pick guide star" and click on your chosen star in the guide camera image.-->
# Click the "Pick G_Star" button in the "Guiding" panel, which will turn dark blue to indicate that it's ready to receive your guide star selection.
Bus 001 Device 079: ID 1278:0507 Starlight Xpress Lodestar autoguider
Bus 001 Device 081: ID 1278:0507 Starlight Xpress Lodestar autoguider
There is one Lodestar camera each for SHOC Mookodi and Sibonise. If you see one Starlight Xpress in the list it might just be the one you need, so try the next steps. If you do not see any Starlight Xpress listed then the cameras are not detected on the USB ports and the icron devices probably need power cycling (call electronics standby).
