08:23:05 This is AcquireScheduler V9.0.3
08:23:05 Custom image file path/names are in use
08:23:05   [PreFlip=300 PostFlip=300 AF=180 PU=60]
08:23:05 Hardware GEM pier side reporting is available.
08:23:06 Initializing AcquireSupport V9.0.3
08:23:06 Weather safe, server is Boltwood Cloud Sensor II
08:23:06 Telescope is ACP->TM61, driver V3
08:23:06 Dome is MaxDome
08:23:07 MaxIm DL is version 6.28
08:23:07 Imager is ASCOM
08:23:07 Using focus offsets and star mags from FilterInfo.txt
08:23:07 Selecting filter V from previous ACP run at 20240127@081727 UTC
08:23:07 Imager readout modes:
08:23:07   0 is Fast
08:23:07   1 is Normal
08:23:07 Guider is SX Universal (no rotator)
08:23:07 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
08:23:07 Max unguided exposure 60 sec.
08:23:07 Guider is set to multi-star mode
08:23:07 (assuring that FocusMax is running now...)
08:23:07 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
08:23:07 Calculated field of view (arcmin): H = 36.3 V = 24.3
08:23:07 Plate solving with GSC 1.1 (ok for wider fields)
08:23:07 Mount supports tracking rate offsets
08:23:07 ==== Starting target 3C_279 ====
08:23:07 ACPS Observation 3C_279(1 of 1)
08:23:07   (belongs to Project AAVSO_survey_HQ_AUTO_ver3479, Plan 3C_279)
08:23:07   (turning on sidereal tracking)
08:23:07 Pointing updates are enabled
08:23:07 Catalog Maximum Mag = 18.0
08:23:07   Start slew to 3C_279...
08:23:09   (wait for slew to complete)
08:23:34   (slew complete)
08:23:34     [flip check:  Tn=460s HAc=-11770s GW=T HAz=-11310s DWz=T WF=no]
08:23:34   Updating pointing...
08:23:34   Switching from V to SR filter for pointing exposure
08:23:34   Focus change of -290 steps required
08:23:37   (taking 10 sec. exposure, SR filter, binning = 4)
08:23:37   (using Fast readout mode)
08:23:37   (starting exposure)
08:24:02   (exposure complete)
08:24:04   (exposure complete and image downloaded)
08:24:06   Image finished
08:24:06   Plate-solve pointing image.
08:24:06   159 image stars found
08:24:07   144 catalog stars found
08:24:08   Solved! 42 stars matched.
08:24:08   Average residual is 0.38 arcsec.
08:24:08   Pointing error is 1.795 arcmin @ angle 81.19
08:24:08   True focal length is 3469.1 mm.
08:24:08   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
08:24:08   True image center (J2000): 12h 56m 18.2s   -05° 47' 05.51"
08:24:08   Imager sky position angle is 178.8 deg.
08:24:08   [sync] pointing model updated
08:24:08   Within max error tolerance, no re-slew needed.
08:24:08   Target is now centered.
08:24:08   (high cadence option, no web previews)
08:24:08   (aggregated exposure times, trying to autoguide)
08:24:08   Switching from SR to SU filter for imaging
08:24:08   No focus change required
