08:12:35 Selecting filter SG from previous ACP run at 20250524@081052 UTC
08:12:35 Imager readout modes:
08:12:35   0 is Fast
08:12:35   1 is Normal
08:12:35 Guider is SX Universal (no rotator)
08:12:35 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
08:12:35 Max unguided exposure 60 sec.
08:12:35 Guider is set to multi-star mode
08:12:35 (assuring that FocusMax is running now...)
