74" / 1.9m - Instrument Selector

184 bytes added, 22 February
/* Instrument Description */
Below is the image showing the new SHOC system mounted to the side of SpUpNIC's acquisition box. The new SHOC system replaces the old guider box that use to migrate between SpUpNIC and HiPPo. The new SHOC system is incorporated into a newly designed off-axis "pick-off" style guider system that can accommodate a filter wheel unit and SHOC camera behind the guider.
To select between the primary instrument and SHOC, a user can actuate the fold mirror in/out of the beam to direct the science beam towards the desired instrument (see figure Figure 2 below for that indicates the button on TCS that actuates the fold mirror). When the fold mirror is IN beam and the guider's XY stages are "centred" then the guider camera also functions as a "target acquisition" camera for SpUpNIC/HiPPo, similar to the old system. Also as in the old system, the guider can patrol the area of the large annulas mirror to acquire an appropriate guide star. [[File:mookodi_sat_pred_vs_source_pos.gif|frame|left|Figure2: Button (and indicator) that actuates the fold mirror. It will remain green in both states (IN or OUT)]]
