Pan around the main field while averaging using the cursor keys on the keypad. Let the staff know before your run if you wish to use it. The new guider can be started or stopped using the xguider window on chichon. Parameters can only be changed from the PC keyboard. The program will prompt you for which telescope you are on, and restore the appropriate values.
Cursors are reset to the center of the screen.
Turn up the high voltage, and after finding a quide star, hit 'z' for guiding on bright stars, or 'Z' for faint stars. Then repeatedly hit '5' to decrease or '6' to increase the sky value. Aim for sky between 20 and 60, as determined by the intensity reading on the lower right of the monitor, or returned when hitting the space bar on the PC keyboard. The intensity displayed on the monitor is that corresponding to the central pixel of the active cursor. Saturation is 255 - but if a few pixels in the core of the star saturate, don't let it concern you.
