05:07:17 This is AcquireScheduler V9.1.3
05:07:17 Custom image file path/names are in use
05:07:17   [PreFlip=300 PostFlip=300 AF=180 PU=60]
05:07:17 Hardware GEM pier side reporting is available.
05:07:18 Initializing AcquireSupport V9.2.4
05:07:18 Weather safe, server is Boltwood Cloud Sensor II
05:07:18 Telescope is ACP->TM61, driver V3
05:07:18 Dome is MaxDome
05:07:18 MaxIm DL is version 6.28
05:07:18 Imager is ASCOM
05:07:18 Using focus offsets and star mags from FilterInfo.txt
05:07:18 Selecting filter V from previous ACP run at 20250526@050546 UTC
05:07:18 Imager readout modes:
05:07:18   0 is Fast
05:07:18   1 is Normal
05:07:18 Guider is SX Universal (no rotator)
05:07:18 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
05:07:18 Max unguided exposure 59 sec.
05:07:18 Guider is set to multi-star mode
05:07:18 (assuring that FocusMax is running now...)
05:07:26 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
05:07:26 Calculated field of view (arcmin): H = 36.3 V = 24.3
05:07:26 Plate solving with GSC 1.1 (ok for wider fields)
05:07:26 Mount supports tracking rate offsets

05:08:18   Switching from V to SR filter for pointing exposure
05:08:18   Focus change of -290 steps required
05:08:22   (taking 10 sec. exposure, SR filter, binning = 4)
05:08:22   (using Fast readout mode)
05:08:22   (starting exposure)
05:08:44   (exposure complete)

05:08:48   Focuser temp (deg.C) = 21.9
05:08:48   Image finished
05:08:48   Plate-solve pointing image.
05:08:49   627 image stars found
05:08:49   173 catalog stars found
05:08:50   Solved! 52 stars matched.
05:08:50   Average residual is 0.33 arcsec.
05:08:50   Pointing error is 8.347 arcmin @ angle 252.76
05:08:50   True focal length is 3468.6 mm.
05:08:50   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89

05:08:50   Imager sky position angle is 178.9 deg.
05:08:50   [sync] pointing model updated
05:08:50   Re-slew to target.
05:08:50   Start slew to NGC_6171...
05:08:51   (wait for slew to complete)
05:09:06   (slew complete)
05:09:06   Target is now centered.
05:09:06   (high cadence option, no web previews)
05:09:06   (long exposure, trying to autoguide)
05:09:06   Switching from SR to SG filter for imaging
05:09:06   Focus change of 50 steps required
05:09:08   (take guider image at initial interval 5 sec)
05:09:18   Multi-star guiding, MaxIm chose star at X=369.9802 Y=122.8289
05:09:18   (guide star SNR=13.1 X=370 Y=123)
05:09:19   (first exposure estimate 1.14 sec)
05:09:23 ** This guide star disappeared or moved > 20 pixels. Can't continue.
05:09:24 **No usable stars this time, must be extremely weak, giving up.
05:09:24 **Autoguiding failed.
