08:28:54 This is AcquireScheduler V9.1.3
08:28:54 Custom image file path/names are in use
08:28:54   [PreFlip=300 PostFlip=300 AF=180 PU=60]
08:28:54 Hardware GEM pier side reporting is available.
08:28:55 Initializing AcquireSupport V9.2.4
08:28:55 Weather safe, server is Boltwood Cloud Sensor II
08:28:55 Telescope is ACP->TM61, driver V3
08:28:55 Dome is MaxDome
08:28:55 MaxIm DL is version 6.28
08:28:55 Imager is ASCOM
08:28:55 Using focus offsets and star mags from FilterInfo.txt
08:28:55 Selecting filter V from previous ACP run at 20250605@082836 UTC
08:28:55 Imager readout modes:
08:28:55   0 is Fast
08:28:55   1 is Normal
08:28:55 Guider is SX Universal (no rotator)
08:28:55 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
08:28:55 Max unguided exposure 59 sec.
08:28:55 Guider is set to multi-star mode
08:28:55 (assuring that FocusMax is running now...)
08:29:03 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
08:29:03 Calculated field of view (arcmin): H = 36.3 V = 24.3
08:29:03 Plate solving with GSC 1.1 (ok for wider fields)
08:29:03 Mount supports tracking rate offsets

08:29:03 ACPS Observation NGC_6864(1 of 1)
08:29:03   (belongs to Project AAVSO_Pgc_Welch_AUTO_ver4538, Plan NGC_6864)
08:29:03   (turning on sidereal tracking)
08:29:03 Pointing updates are enabled
08:29:03 Catalog Maximum Mag = 18.0
08:29:03   Start slew to NGC_6864...
08:29:05   (wait for slew to complete)

08:29:49   Switching from V to SR filter for pointing exposure
08:29:49   Focus change of -290 steps required
08:29:54   (taking 10 sec. exposure, SR filter, binning = 4)
08:29:54   (using Fast readout mode)
08:29:54   (starting exposure)
08:30:16   (exposure complete)
08:30:19   (exposure complete and image downloaded)
08:30:19   Camera temp (deg.C) = -8
08:30:20   Focuser position = 3338
08:30:20   Focuser temp (deg.C) = 22.2
08:30:20   Image finished
08:30:20   Plate-solve pointing image.

08:30:21   285 catalog stars found
08:30:22   Solved! 102 stars matched.
08:30:22   Average residual is 0.3 arcsec.
08:30:22   Pointing error is 0.944 arcmin @ angle 94.96
08:30:22   True focal length is 3465.8 mm.
08:30:22   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
08:30:22   True image center (J2000): 20h 06m 08.7s   -21° 55' 21.09"
08:30:22   Imager sky position angle is 179.0 deg.
08:30:22   [sync] pointing model updated
08:30:22   Within max error tolerance, no re-slew needed.
08:30:22   Target is now centered.
08:30:22   (high cadence option, no web previews)
08:30:22   (long exposure, trying to autoguide)
08:30:22   Switching from SR to SG filter for imaging
08:30:22   Focus change of 50 steps required
08:30:25   (take guider image at initial interval 5 sec)
08:30:35   Multi-star guiding, MaxIm chose star at X=563.7875 Y=832.0995
