07:31:56 Selecting filter SR from previous ACP run at 20240412@073030 UTC
07:31:56 Imager readout modes:
07:31:56   0 is Fast
07:31:56   1 is Normal
07:31:56 Guider is SX Universal (no rotator)
07:31:56 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
07:31:56 Max unguided exposure 60 sec.
07:31:56 Guider is set to multi-star mode
07:31:56 (assuring that FocusMax is running now...)
07:31:56 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
