== Acquiring a target with shocnwonder on the instrument selector ==
The instrument selector has replaced the old acquisition box, though the guide mirror remains. With shocnwonder mounted on the instrument selector, the acquisition procedure is slightly different from when past imaging cameras were mounted on the acquisition box. Whereas before, one would centre the guide mirror to allow the beam to pass through the central hole in the guide mirror to the camera, that hole is now covered by a fold mirror that directs the beam to shocnwonder, which is mounted at a 90 degree angle, effectively in the "initialise" position of the old acquisition & guiding camera. The new guide camera is mounted on linear stages that move in X and Y across the guide star finderchart field of view. If the guide camera is centred, it will obscure the SHOC beam, so it should always be away from centre when using SHOC. The XY slide coordinates at the centre of the field are (7150, 82000).
