Licensed to Arne Henden
05:24:06 This is AcquireScheduler V9.1.3
05:24:06 Custom image file path/names are in use
05:24:06   [PreFlip=300 PostFlip=300 AF=180 PU=60]
05:24:06 Hardware GEM pier side reporting is available.
05:24:07 Initializing AcquireSupport V9.2.4
05:24:07 Weather safe, server is Boltwood Cloud Sensor II
05:24:07 Telescope is ACP->TM61, driver V3
05:24:07 Dome is MaxDome
05:24:08 MaxIm DL is version 6.28
05:24:08 Imager is ASCOM
05:24:08 Using focus offsets and star mags from FilterInfo.txt
05:24:08 Selecting filter SG from previous ACP run at 20250605@052052 UTC
05:24:08 Imager readout modes:
05:24:08   0 is Fast
05:24:08   1 is Normal
05:24:08 Guider is SX Universal (no rotator)
05:24:08 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
05:24:08 Max unguided exposure 59 sec.
05:24:08 Guider is set to multi-star mode
05:24:08 (assuring that FocusMax is running now...)
05:24:15 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
05:24:15 Calculated field of view (arcmin): H = 36.3 V = 24.3
05:24:15 Plate solving with GSC 1.1 (ok for wider fields)
05:24:15 Mount supports tracking rate offsets

05:24:52   Switching from SG to SR filter for pointing exposure
05:24:52   Focus change of -50 steps required
05:24:55   (taking 10 sec. exposure, SR filter, binning = 4)
05:24:55   (using Fast readout mode)
05:24:55   (starting exposure)
05:25:14   (exposure complete)
05:25:16   (exposure complete and image downloaded)
05:25:16   Camera temp (deg.C) = -5.9
05:25:17   Focuser position = 3331
05:25:17   Focuser temp (deg.C) = 23.8
05:25:17   Image finished
05:25:17   Plate-solve pointing image.

05:25:18   342 catalog stars found
05:25:20   Solved! 151 stars matched.
05:25:20   Average residual is 0.29 arcsec.
05:25:20   Pointing error is 3.050 arcmin @ angle 84.66
05:25:20   True focal length is 3469.4 mm.
05:25:20   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89

05:25:20   Imager sky position angle is 179.0 deg.
05:25:20   [sync] pointing model updated
05:25:20   Re-slew to target.
05:25:20   Start slew to NGC_6535...
05:25:21   (wait for slew to complete)
05:25:36   (slew complete)
05:25:36   Target is now centered.
05:25:36   (high cadence option, no web previews)
05:25:36   (long exposure, trying to autoguide)
05:25:36   Switching from SR to SG filter for imaging
05:25:36   Focus change of 50 steps required
05:25:39   (take guider image at initial interval 5 sec)
05:25:48   Multi-star guiding, MaxIm chose star at X=850.8992 Y=58.3211
05:25:49 ** This guide star disappeared or moved > 20 pixels. Can't continue.
05:25:49 **No usable stars in guider image; trying again at max guider exposure
05:26:02   Multi-star guiding, MaxIm chose star at X=1325.903 Y=607.999
05:26:02   (guide star SNR=26.3 X=1326 Y=608)
05:26:03   (first exposure estimate 1.14 sec)
05:26:08 ** This guide star disappeared or moved > 20 pixels. Can't continue.
05:26:08 **No usable stars this time, must be extremely weak, giving up.
05:26:08 **Autoguiding failed.
