08:20:31 Imager readout modes:
08:20:31   0 is Fast

08:20:31 Guider is SX Universal (no rotator)
08:20:31 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
08:20:31 Max unguided exposure 60 sec.
08:20:31 Guider is set to multi-star mode
08:20:31 (assuring that FocusMax is running now...)
