Licensed to Arne Henden
03:50:21 This is AcquireScheduler V9.0.3
03:50:21 Custom image file path/names are in use
03:50:21   [PreFlip=300 PostFlip=300 AF=180 PU=60]
03:50:21 Hardware GEM pier side reporting is available.
03:50:22 Initializing AcquireSupport V9.0.3
03:50:22 Weather safe, server is Boltwood Cloud Sensor II
03:50:22 Telescope is ACP->TM61, driver V3
03:50:22 Dome is MaxDome
03:50:22 MaxIm DL is version 6.28
03:50:22 Imager is ASCOM
03:50:22 Using focus offsets and star mags from FilterInfo.txt
03:50:22 Selecting filter B from previous ACP run at 20240118@034946 UTC
03:50:22 Imager readout modes:
03:50:22   0 is Fast
03:50:22   1 is Normal
03:50:22 Guider is SX Universal (no rotator)
03:50:22 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
03:50:22 Max unguided exposure 60 sec.
03:50:22 Guider is set to multi-star mode
03:50:22 (assuring that FocusMax is running now...)
03:50:22 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
03:50:22 Calculated field of view (arcmin): H = 36.3 V = 24.3
03:50:22 Plate solving with GSC 1.1 (ok for wider fields)
03:50:22 Mount supports tracking rate offsets
03:50:22 ==== Starting target OJ287 ====
03:50:22 ACPS Observation OJ287(1 of 1)
03:50:22   (belongs to Project AAVSO_MISC_PYG_AUTO_ver3260, Plan OJ287)
03:50:22   (turning on sidereal tracking)
03:50:22 Pointing updates are enabled
03:50:22 Catalog Maximum Mag = 18.0
03:50:22   Start slew to OJ287...
03:50:24   (wait for slew to complete)
03:51:19   (slew complete)
03:51:19     [flip check:  Tn=480s HAc=-15805s GW=T HAz=-15325s DWz=T WF=no]
03:51:19   Updating pointing...
03:51:19   Switching from B to SR filter for pointing exposure
03:51:19   Focus change of -320 steps required
03:51:22   (taking 10 sec. exposure, SR filter, binning = 4)
03:51:22   (using Fast readout mode)
03:51:22   (starting exposure)
03:51:48   (exposure complete)
03:51:50   (exposure complete and image downloaded)
03:51:51   Image finished
03:51:51   Plate-solve pointing image.
03:51:52   230 image stars found
03:51:52   211 catalog stars found
03:51:53   Solved! 78 stars matched.
03:51:53   Average residual is 0.39 arcsec.
03:51:53   Pointing error is 1.937 arcmin @ angle 260.93
03:51:53   True focal length is 3464.0 mm.
03:51:53   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
03:51:53   True image center (J2000): 08h 54m 40.8s   20° 06' 12.26"
03:51:53   Imager sky position angle is 178.8 deg.
03:51:53   [sync] pointing model updated
03:51:53   Within max error tolerance, no re-slew needed.
03:51:53   Target is now centered.
03:51:53   (high cadence option, no web previews)
03:51:53   (aggregated exposure times, trying to autoguide)
03:51:53   Switching from SR to B filter for imaging
03:51:53   Focus change of 320 steps required
03:51:57   (take guider image at initial interval 5 sec)
03:52:10   Multi-star guiding, MaxIm chose star at X=859 Y=830.996
03:52:10 **No stars at all found in guider image
03:52:10 **No usable stars in guider image; trying again at max guider exposure
03:52:23   Multi-star guiding, MaxIm chose star at X=0 Y=0
03:52:24 ** This guide star disappeared or moved > 20 pixels. Can't continue.
03:52:24 **No usable stars at max guider exposure interval, can't guide
03:52:24 **Autoguiding failed.
