02:09:00 Weather safe, server is Boltwood Cloud Sensor II
02:09:00 Telescope is ACP->TM61, driver V3
02:09:00 Dome is MaxDome
02:09:00 MaxIm DL is version 6.28
02:09:00 Imager is ASCOM

02:09:00 Selecting filter B from previous ACP run at 20240215@020825 UTC
02:09:00 Imager readout modes:
02:09:00   0 is Fast
02:09:00   1 is Normal

02:09:00 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:09:00 Max unguided exposure 60 sec.
02:09:00 Guider is set to multi-star mode
02:09:00 (assuring that FocusMax is running now...)
02:09:00 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:09:00 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:09:00 Plate solving with GSC 1.1 (ok for wider fields)
