02:02:54 This is AcquireScheduler V9.0.3
02:02:54 Custom image file path/names are in use

02:02:54 Hardware GEM pier side reporting is available.
02:02:55 Initializing AcquireSupport V9.0.3
02:02:55 Weather safe, server is Boltwood Cloud Sensor II
02:02:55 Telescope is ACP->TM61, driver V3
02:02:55 Dome is MaxDome
02:02:55 MaxIm DL is version 6.28
02:02:55 Imager is ASCOM
02:02:55 Using focus offsets and star mags from FilterInfo.txt
02:02:55 Selecting filter B from previous ACP run at 20240221@020220 UTC
02:02:55 Imager readout modes:
02:02:55   0 is Fast
02:02:55   1 is Normal
02:02:55 Guider is SX Universal (no rotator)
02:02:55 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:02:55 Max unguided exposure 60 sec.
02:02:55 Guider is set to multi-star mode
02:02:55 (assuring that FocusMax is running now...)
02:02:55 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:02:55 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:02:55 Plate solving with GSC 1.1 (ok for wider fields)
02:02:55 Mount supports tracking rate offsets

02:02:55   (turning on sidereal tracking)
02:02:56 Pointing updates are enabled
02:02:56 Catalog Maximum Mag = 18.0
02:02:56   Start slew to V838_Mon...

02:03:26   Switching from B to SR filter for pointing exposure
02:03:26   Focus change of -320 steps required
02:03:30   (taking 10 sec. exposure, SR filter, binning = 4)
02:03:30   (using Fast readout mode)
02:03:30   (starting exposure)

02:04:00   Image finished
02:04:00   Plate-solve pointing image.
02:04:00   2112 image stars found
02:04:00   483 catalog stars found
02:04:01   Solved! 186 stars matched.
02:04:01   Average residual is 0.25 arcsec.
02:04:01   Pointing error is 1.834 arcmin @ angle 78.85
02:04:01   True focal length is 3468.4 mm.
02:04:01   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89

02:04:02   [sync] pointing model updated
02:04:02   Within max error tolerance, no re-slew needed.
02:04:02   Target is now centered.
