** A '''red marker position of (370, 270)''' is a good place to start in centring an object on SpUpNIC's slit.
** An autoguider camera focus value of 6000 is a good starting point with SpUpNIC/SHOC.
** It is currently necessary to kill the guide star finderchart image display box on the TSCTCS, before pressing "Read" to import the target coordinates from SpUpNIC in order to load the new guide star finder.
** The area within the green circle on the finderchart no longer marks the usable guide star region - guide stars within parts of the circle are accessible to the XY slides. The XY slide ranges are (0 < X < 14000, 0 < Y < 91000).
** The new guide camera field is larger and the chip has far fewer hot pixels to upset the guiding.
