02:04:48 This is AcquireScheduler V9.0.3
02:04:48 Custom image file path/names are in use

02:04:49 Weather safe, server is Boltwood Cloud Sensor II
02:04:49 Telescope is ACP->TM61, driver V3
02:04:50 Dome is MaxDome
02:04:50 MaxIm DL is version 6.28
02:04:50 Imager is ASCOM
02:04:50 Using focus offsets and star mags from FilterInfo.txt
02:04:50 Selecting filter V from previous ACP run at 20240217@020430 UTC
02:04:50 Imager readout modes:
02:04:50   0 is Fast
02:04:50   1 is Normal
02:04:50 Guider is SX Universal (no rotator)
02:04:50 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:04:50 Max unguided exposure 60 sec.
02:04:50 Guider is set to multi-star mode
02:04:50 (assuring that FocusMax is running now...)
02:04:50 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:04:50 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:04:50 Plate solving with GSC 1.1 (ok for wider fields)
02:04:50 Mount supports tracking rate offsets
