05:23:14 This is AcquireScheduler V9.1.3
05:23:14 Custom image file path/names are in use
05:23:14   [PreFlip=300 PostFlip=300 AF=180 PU=60]
05:23:14 Hardware GEM pier side reporting is available.
05:23:15 Initializing AcquireSupport V9.2.4
05:23:15 Weather safe, server is Boltwood Cloud Sensor II
05:23:15 User actions detected.
05:23:15 Telescope is ACP->TM61, driver V3
05:23:15 Dome is MaxDome
05:23:15 MaxIm DL is version 6.28
05:23:15 Imager is ASCOM
05:23:15 Using focus offsets and star mags from FilterInfo.txt
05:23:15 Selecting filter SZ from previous ACP run at 20250614@052235 UTC
05:23:15 Imager readout modes:
05:23:15   0 is Fast
05:23:15   1 is Normal
05:23:15 Guider is SX Universal (no rotator)
05:23:15 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
05:23:15 Max unguided exposure 59 sec.
05:23:15 Guider is set to multi-star mode
05:23:15 (assuring that FocusMax is running now...)
05:23:23 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
05:23:23 Calculated field of view (arcmin): H = 36.3 V = 24.3
05:23:23 Plate solving with GSC 1.1 (ok for wider fields)
05:23:23 Mount supports tracking rate offsets

05:24:15   Switching from SZ to SR filter for pointing exposure
05:24:15   Focus change of 50 steps required
05:24:18   (taking 10 sec. exposure, SR filter, binning = 4)

05:24:40   173 catalog stars found
05:24:41   Solved! 72 stars matched.
05:24:41   Average residual is 0.36 arcsec.
05:24:41   Pointing error is 1.443 arcmin @ angle 152.95
05:24:41   True focal length is 3466.2 mm.
05:24:41   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
05:24:41   True image center (J2000): 16h 32m 34.6s   -13° 04' 30.72"
05:24:41   Imager sky position angle is 179.0 deg.
05:24:41   [sync] pointing model updated
05:24:41   Within max error tolerance, no re-slew needed.
05:24:41   Target is now centered.
05:24:41   (high cadence option, no web previews)
05:24:41   (long exposure, trying to autoguide)
05:24:41   Switching from SR to SG filter for imaging
05:24:41   Focus change of 50 steps required
05:24:44   (take guider image at initial interval 5 sec)
05:24:53   Multi-star guiding, MaxIm chose star at X=1326.027 Y=607.7922
05:24:54 ** This guide star disappeared or moved > 20 pixels. Can't continue.
05:24:54 **No usable stars in guider image; trying again at max guider exposure
05:25:06   Multi-star guiding, MaxIm chose star at X=443.9127 Y=951.9991
05:25:07   (guide star SNR=57.0 X=444 Y=952)
05:25:07   (first exposure estimate 1 sec)
05:25:11 ** This guide star disappeared or moved > 20 pixels. Can't continue.
05:25:12 **No usable stars this time, must be extremely weak, giving up.
05:25:12 **Autoguiding failed.
