02:34:08 Selecting filter B from previous ACP run at 20250224@022828 UTC
02:34:08 Imager readout modes:
02:34:08   0 is Fast
02:34:08   1 is Normal
02:34:08 Guider is SX Universal (no rotator)
02:34:08 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:34:08 Max unguided exposure 60 sec.
02:34:08 Guider is set to multi-star mode
02:34:08 (assuring that FocusMax is running now...)
02:34:16 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:34:16 Calculated field of view (arcmin): H = 36.3 V = 24.3
