=== Biases and flats ===
# Move the fold mirror into the beam: on the right-hand side of the TCS GUI there is a large green button that will either say "Fold mirror is in beam", or "Fold mirror is out of beam". If it doesn't say the former, click it to make it so. # Park the guide camera in the top-right-hand corner of the guide star field of view (represented by the finderchart on the TCS: click "GoTo" in the TCS GUI: XY Slides Control, and enter X=500, Y=20000. Wait a few moments for the camera to move then check that it reached the desired coordinates.# Take biases or flats as per the usual SHOC procedures. === Observing a target ===
The procedure for acquiring a target with SHOCnWonder on the 1.9m is as follows:
'''5.''' Press “Auto” on TCS GUI (telescope will slew to target)
'''To ensure that the guide camera is away from the centre of the field -- to avoid obscuring the SHOC beam -- you should select your guide star nowCheck fold mirror and focus on TCS GUI:'''
'''6.'''

'''12.''' Acquire field on SHOC:
'''Start guiding:'''
'''13.''' Check that there is a guide star in the Acquisition & Guiding Control image, if not, repeat steps 6 9 & 710
'''14.''' On TCS GUI: Pointer - press “Guide Star”
'''Start photometry:'''
'''16.''' On SHOC GUI - configure and take science exposures. For multiple filter cycling, configure SHOC then follow these instructions.
'''17.''' To acquire the next target, '''do not initialise the XY slides''' - this should only be done if there is a fault, in which case the Reset and Initialise buttons will turn red and should be pressed in that order. To move from one target to the next, simply repeat the procedure above from step 1.
