05:46:24 This is AcquireScheduler V9.1.3
05:46:24 Custom image file path/names are in use
05:46:24   [PreFlip=300 PostFlip=300 AF=180 PU=60]
05:46:24 Hardware GEM pier side reporting is available.
05:46:25 Initializing AcquireSupport V9.2.4
05:46:25 Weather safe, server is Boltwood Cloud Sensor II
05:46:25 Telescope is ACP->TM61, driver V3
05:46:25 Dome is MaxDome
05:46:25 MaxIm DL is version 6.28
05:46:25 Imager is ASCOM
05:46:25 Using focus offsets and star mags from FilterInfo.txt
05:46:25 Selecting filter SG from previous ACP run at 20250605@054547 UTC
05:46:25 Imager readout modes:
05:46:25   0 is Fast
05:46:25   1 is Normal
05:46:25 Guider is SX Universal (no rotator)
05:46:25 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
05:46:25 Max unguided exposure 59 sec.
05:46:25 Guider is set to multi-star mode
05:46:25 (assuring that FocusMax is running now...)
05:46:32 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
05:46:32 Calculated field of view (arcmin): H = 36.3 V = 24.3
05:46:32 Plate solving with GSC 1.1 (ok for wider fields)
05:46:32 Mount supports tracking rate offsets

05:46:33 ACPS Observation NGC_6144(1 of 1)
05:46:33   (belongs to Project AAVSO_Pgc_Welch_AUTO_ver4538, Plan NGC_6144)
05:46:33   (turning on sidereal tracking)
05:46:33 Pointing updates are enabled
05:46:33 Catalog Maximum Mag = 18.0
05:46:33   Start slew to NGC_6144...
05:46:34   (wait for slew to complete)
05:47:04   (slew complete)

05:47:04   Switching from SG to SR filter for pointing exposure
05:47:04   Focus change of -50 steps required
05:47:06   (taking 10 sec. exposure, SR filter, binning = 4)
05:47:06   (using Fast readout mode)
05:47:06   (starting exposure)
05:47:25   (exposure complete)
05:47:27   (exposure complete and image downloaded)
05:47:27   Camera temp (deg.C) = -6.3
05:47:29   Focuser position = 3331
05:47:29   Focuser temp (deg.C) = 23.7
05:47:29   Image finished
05:47:29   Plate-solve pointing image.
05:47:30   953 image stars found
05:47:30   206 catalog stars found
05:47:31   Solved! 64 stars matched.
05:47:31   Average residual is 0.26 arcsec.
05:47:31   Pointing error is 0.784 arcmin @ angle 95.98
05:47:31   True focal length is 3469.3 mm.
05:47:31   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
05:47:31   True image center (J2000): 16h 27m 17.3s   -26° 01' 29.50"
05:47:31   Imager sky position angle is 178.9 deg.
05:47:31   [sync] pointing model updated
05:47:31   Within max error tolerance, no re-slew needed.
05:47:31   Target is now centered.
05:47:31   (high cadence option, no web previews)
05:47:31   (long exposure, trying to autoguide)
05:47:31   Switching from SR to SG filter for imaging
05:47:31   Focus change of 50 steps required
05:47:34   (take guider image at initial interval 5 sec)
05:47:44   Multi-star guiding, MaxIm chose star at X=137.0565 Y=862.2123
05:47:44   (guide star SNR=13.3 X=137 Y=862)
05:47:45   (first exposure estimate 1.13 sec)

05:47:49   (final exposure for guiding 1.02 sec)
05:47:54   (guide star SNR=2.7 X=138 Y=862)
05:48:07 **Guider waited for 10 sec and never got a measurement

05:48:12   Multi-star guiding, MaxIm chose star at X=0 Y=0
05:48:13 ** This guide star disappeared or moved > 20 pixels. Can't continue.
05:48:13 **No usable stars in guider image; trying again at max guider exposure
05:48:26   Multi-star guiding, MaxIm chose star at X=1325.988 Y=607.8066
05:48:27 ** This guide star disappeared or moved > 20 pixels. Can't continue.
05:48:27 **No usable stars at max guider exposure interval, can't guide
05:48:27 **Autoguiding failed.
