Look for "Starlight Xpress Lodestar autoguider" in output

# Start rts2 control of Lodestar on the pi:

ssh pi@1mag1.suth.saao.ac.za

sudo bash

/etc/init.d/rts2 start

# Take images with the Lodestar:

ssh -X observer@1ms1.suth.saao.ac.za

rts2-xfocusc -d AG1CCD -e 1

(where AG1CCD is on DER1 and -e is the exposure time option).

# Take and save an image with the Lodestar:

CTRL-C out of rts2-xfocusc

rts2-scriptexec -d AG1CCD -s 'E 1'

# Loop multiple saved images:

rts2-scriptexec -d AG1CCD -s 'for 5 {E 1}'

(also rts2-xfocusc --save)
