03:00:30 Selecting filter B from previous ACP run at 20250123@025854 UTC
03:00:30 Imager readout modes:
03:00:30   0 is Fast
03:00:30   1 is Normal
03:00:30 Guider is SX Universal (no rotator)
03:00:30 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
03:00:30 Max unguided exposure 60 sec.
03:00:30 Guider is set to multi-star mode
