01:52:53 This is AcquireScheduler V9.0.3
01:52:53 Custom image file path/names are in use
01:52:53   [PreFlip=300 PostFlip=300 AF=180 PU=60]
01:52:53 Hardware GEM pier side reporting is available.
01:52:54 Initializing AcquireSupport V9.0.3
01:52:54 Weather safe, server is Boltwood Cloud Sensor II
01:52:54 Telescope is ACP->TM61, driver V3
01:52:54 Dome is MaxDome
01:52:54 MaxIm DL is version 6.28
01:52:54 Imager is ASCOM
01:52:54 Using focus offsets and star mags from FilterInfo.txt
01:52:54 Selecting filter SR from previous ACP run at 20240215@014704 UTC
01:52:54 Imager readout modes:
01:52:54   0 is Fast
01:52:54   1 is Normal
01:52:54 Guider is SX Universal (no rotator)
01:52:54 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
01:52:54 Max unguided exposure 60 sec.
01:52:54 Guider is set to multi-star mode
01:52:54 (assuring that FocusMax is running now...)
01:52:54 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
01:52:54 Calculated field of view (arcmin): H = 36.3 V = 24.3
01:52:54 Plate solving with GSC 1.1 (ok for wider fields)
01:52:54 Mount supports tracking rate offsets
01:52:54 ==== Starting target KN_Lyn ====
01:52:54 ACPS Observation KN_Lyn(1 of 1)
01:52:54   (belongs to Project AAVSO_MISC_HQA_AUTO_ver3479, Plan KN_Lyn)
01:52:54   (turning on sidereal tracking)
01:52:55 Pointing updates are enabled
01:52:55 Catalog Maximum Mag = 18.0
01:52:55   Start slew to KN_Lyn...
01:52:56   (wait for slew to complete)
01:54:11   (slew complete)
01:54:11     [flip check:  Tn=502s HAc=-13958s GW=T HAz=-13455s DWz=T WF=no]
01:54:11   Updating pointing...
01:54:11   (taking 10 sec. exposure, SR filter, binning = 4)
01:54:11   (using Fast readout mode)
01:54:11   (starting exposure)
01:54:27   (exposure complete)
01:54:30   (exposure complete and image downloaded)
01:54:31   Image finished
01:54:31   Plate-solve pointing image.
01:54:31   281 image stars found
01:54:31   252 catalog stars found
01:54:32   Solved! 93 stars matched.
01:54:33   Average residual is 0.32 arcsec.
01:54:33   Pointing error is 0.658 arcmin @ angle 241.47
01:54:33   True focal length is 3465.8 mm.
01:54:33   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
01:54:33   True image center (J2000): 08h 16m 33.0s   47° 50' 23.64"
01:54:33   Imager sky position angle is 178.7 deg.
01:54:33   [sync] pointing model updated
01:54:33   Within max error tolerance, no re-slew needed.
01:54:33   Target is now centered.
01:54:33   (high cadence option, no web previews)
01:54:33   (aggregated exposure times, trying to autoguide)
01:54:33   Switching from SR to SG filter for imaging
01:54:33   Focus change of 50 steps required
01:54:35   (take guider image at initial interval 5 sec)
01:54:45   Multi-star guiding, MaxIm chose star at X=451.9333 Y=347.0965
01:54:46 ** This guide star disappeared or moved > 20 pixels. Can't continue.
01:54:46 **No usable stars in guider image; trying again at max guider exposure
01:54:59   Multi-star guiding, MaxIm chose star at X=249.1564 Y=48.98144
01:54:59   (guide star SNR=8.8 X=249 Y=49)
01:55:00   (first exposure estimate 3.42 sec)
01:55:06   (guide star SNR=3.3 X=250 Y=48)
01:55:07   (final exposure for guiding 3.1 sec)
01:55:14   (guide star SNR=2.9 X=248 Y=47)
01:55:32 **Guider waited for 15.5 sec and never got a measurement
01:55:33   (take guider image at initial interval 3.1 sec)
01:55:40   Multi-star guiding, MaxIm chose star at X=452.0007 Y=347
01:55:40 ** This guide star disappeared or moved > 20 pixels. Can't continue.
01:55:41 **No usable stars in guider image; trying again at max guider exposure
01:55:53   Multi-star guiding, MaxIm chose star at X=0 Y=0
01:55:54 ** This guide star disappeared or moved > 20 pixels. Can't continue.
01:55:54 **No usable stars at max guider exposure interval, can't guide
01:55:54 **Autoguiding failed.
