01:59:45 This is AcquireScheduler V9.0.3
01:59:45 Custom image file path/names are in use
01:59:45   [PreFlip=300 PostFlip=300 AF=180 PU=60]
01:59:45 Hardware GEM pier side reporting is available.
01:59:46 Initializing AcquireSupport V9.0.3
01:59:46 Weather safe, server is Boltwood Cloud Sensor II
01:59:46 Telescope is ACP->TM61, driver V3
01:59:46 Dome is MaxDome
01:59:46 MaxIm DL is version 6.28
01:59:46 Imager is ASCOM
01:59:46 Using focus offsets and star mags from FilterInfo.txt
01:59:46 Selecting filter SG from previous ACP run at 20240222@015914 UTC
01:59:46 Imager readout modes:
01:59:46   0 is Fast
01:59:46   1 is Normal
01:59:46 Guider is SX Universal (no rotator)
01:59:46 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
01:59:46 Max unguided exposure 60 sec.
01:59:46 Guider is set to multi-star mode
01:59:46 (assuring that FocusMax is running now...)
01:59:46 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
01:59:46 Calculated field of view (arcmin): H = 36.3 V = 24.3
01:59:46 Plate solving with GSC 1.1 (ok for wider fields)
01:59:46 Mount supports tracking rate offsets

01:59:46 ACPS Observation V838_Mon(1 of 1)
01:59:46   (belongs to Project AAVSO_P237_CWT_AUTO_ver3515, Plan V838_Mon)
01:59:46   (turning on sidereal tracking)
01:59:46 Pointing updates are enabled
01:59:46 Catalog Maximum Mag = 18.0
01:59:46   Start slew to V838_Mon...
01:59:48   (wait for slew to complete)

02:00:28   Switching from SG to SR filter for pointing exposure
02:00:28   Focus change of -50 steps required
02:00:30   (taking 10 sec. exposure, SR filter, binning = 4)
02:00:30   (using Fast readout mode)
02:00:30   (starting exposure)
02:00:52   (exposure complete)

02:00:55   Image finished
02:00:55   Plate-solve pointing image.
02:00:56   1097 image stars found
02:00:56   483 catalog stars found
02:00:57   Solved! 161 stars matched.
02:00:57   Average residual is 0.23 arcsec.
02:00:57   Pointing error is 1.461 arcmin @ angle 80.02
02:00:57   True focal length is 3467.5 mm.
02:00:57   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89

02:00:57   [sync] pointing model updated
02:00:57   Within max error tolerance, no re-slew needed.
02:00:57   Target is now centered.
