Licensed to Arne Henden
02:28:13 This is AcquireScheduler V9.0.3
02:28:13 Custom image file path/names are in use
02:28:13   [PreFlip=300 PostFlip=300 AF=180 PU=60]
02:28:13 Hardware GEM pier side reporting is available.
02:28:14 Initializing AcquireSupport V9.0.3
02:28:14 Weather safe, server is Boltwood Cloud Sensor II
02:28:14 Telescope is ACP->TM61, driver V3
02:28:14 Dome is MaxDome
02:28:14 MaxIm DL is version 6.28
02:28:14 Imager is ASCOM
02:28:14 Using focus offsets and star mags from FilterInfo.txt
02:28:14 Selecting filter B from previous ACP run at 20240119@022651 UTC
02:28:14 Imager readout modes:
02:28:14   0 is Fast
02:28:14   1 is Normal
02:28:14 Guider is SX Universal (no rotator)
02:28:14 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:28:14 Max unguided exposure 60 sec.
02:28:14 Guider is set to multi-star mode
02:28:14 (assuring that FocusMax is running now...)
02:28:14 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:28:14 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:28:14 Plate solving with GSC 1.1 (ok for wider fields)
02:28:14 Mount supports tracking rate offsets

02:29:57   Switching from B to SR filter for pointing exposure
02:29:57   Focus change of -320 steps required
02:30:00   (taking 10 sec. exposure, SR filter, binning = 4)
02:30:00   (using Fast readout mode)
02:30:00   (starting exposure)
02:30:26   (exposure complete)
02:30:28   (exposure complete and image downloaded)
02:30:29   Image finished
02:30:29   Plate-solve pointing image.
02:30:30   957 image stars found
02:30:30   483 catalog stars found
02:30:33   Solved! 158 stars matched.
02:30:33   Average residual is 0.25 arcsec.
02:30:33   Pointing error is 3.341 arcmin @ angle 268.13
02:30:33   True focal length is 3464.4 mm.
02:30:33   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89

02:30:33   Imager sky position angle is 178.7 deg.
02:30:33   [sync] pointing model updated
02:30:33   Re-slew to target.
02:30:33   Start slew to V838_Mon...
02:30:34   (wait for slew to complete)
02:30:44   (slew complete)
02:30:44   Target is now centered.
02:30:44   (high cadence option, no web previews)
02:30:44   (aggregated exposure times, trying to autoguide)
02:30:44   Switching from SR to SG filter for imaging
02:30:44   Focus change of 50 steps required
02:30:47   (take guider image at initial interval 5 sec)
02:30:57   Multi-star guiding, MaxIm chose star at X=579.377 Y=684.8633
02:30:57   (guide star SNR=6.2 X=580 Y=685)
02:30:57   (first exposure estimate 2.42 sec)
02:31:03   (guide star SNR=3.7 X=577 Y=683)
02:31:03   (final exposure for guiding 1.98 sec)
02:31:09   (guide star SNR=2.4 X=578 Y=684)
02:31:21 **Guider waited for 10 sec and never got a measurement
02:31:23   (take guider image at initial interval 1.98 sec)
02:31:28   Multi-star guiding, MaxIm chose star at X=1052 Y=359
02:31:29 ** This guide star disappeared or moved > 20 pixels. Can't continue.
02:31:29 **No usable stars in guider image; trying again at max guider exposure
02:31:42   Multi-star guiding, MaxIm chose star at X=32.17501 Y=416.9393
02:31:42 ** This guide star disappeared or moved > 20 pixels. Can't continue.
02:31:42 **No usable stars at max guider exposure interval, can't guide
02:31:42 **Autoguiding failed.
