This is ACP version 9.0 (build 4, ACP 9 Production Release)
Licensed to Arne Henden
02:42:03 This is AcquireScheduler V9.0.3
02:42:03 Custom image file path/names are in use
02:42:03   [PreFlip=300 PostFlip=300 AF=180 PU=60]
02:42:03 Hardware GEM pier side reporting is available.
02:42:04 Initializing AcquireSupport V9.0.3
02:42:04 Weather safe, server is Boltwood Cloud Sensor II
02:42:04 Telescope is ACP->TM61, driver V3
02:42:05 Dome is MaxDome
02:42:05 MaxIm DL is version 6.28
02:42:05 Imager is ASCOM
02:42:05 Using focus offsets and star mags from FilterInfo.txt
02:42:05 Selecting filter SR from previous ACP run at 20230412@023006 UTC
02:42:05 Imager readout modes:
02:42:05   0 is Fast
02:42:05   1 is Normal
02:42:05 Guider is SX Universal (no rotator)
02:42:05 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:42:05 Max unguided exposure 60 sec.
02:42:05 (assuring that FocusMax is running now...)
02:42:05 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:42:05 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:42:05 Plate solving with GSC 1.1 (ok for wider fields)
02:42:05 Mount supports tracking rate offsets
02:42:05 ==== Starting target K2-45b ====
02:42:05 ACPS Observation K2-45b(1 of 1)
02:42:05   (belongs to Project Transit, Plan K2-45b)
02:42:05   (turning on sidereal tracking)
02:42:05 Pointing updates are enabled
02:42:05 Catalog Maximum Mag = 18.0
02:42:05   Start slew to K2-45b...
02:42:06   (wait for slew to complete)
02:43:07   (slew complete)

02:43:07   Updating pointing...
02:43:07   (taking 10 sec. exposure, SR filter, binning = 4)
02:43:07   (using Fast readout mode)
02:43:07   (starting exposure)
02:43:22   (exposure complete)
02:43:24   (exposure complete and image downloaded)
02:43:25   Image finished
02:43:25   Plate-solve pointing image.
02:43:26   209 image stars found
02:43:26   104 catalog stars found
02:43:27   Solved! 21 stars matched.
02:43:27   Average residual is 0.35 arcsec.
02:43:27   Pointing error is 0.480 arcmin @ angle 304.93
02:43:27   True focal length is 3482.9 mm.
02:43:27   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
02:43:27   True image center (J2000): 11h 18m 30.3s   -01° 46' 10.12"
02:43:27   Imager sky position angle is 178.7 deg.
02:43:27   [sync] pointing model updated
02:43:27   Within max error tolerance, no re-slew needed.
02:43:27   Target is now centered.

02:43:27   Imaging to K2-45b-S001-SR-R001-SR
02:43:27   (taking 20 sec. exposure, SR filter, binning = 2)
02:43:27   (using Normal readout mode)
02:43:27   (starting exposure)

02:44:00   Plate-solve K2-45b-S001-SR-R001-SR final image.
02:44:03   694 image stars found
02:44:03   60 catalog stars found
02:44:04 ** Focal length off by more than 10%, solution rejected.
02:44:04   (high cadence option, no web previews)
02:44:04   (long exposure, trying to autoguide)
02:44:04   Switching from SR to SR+D25 filter for imaging
02:44:04   No focus change required
02:44:04   (take guider image at initial interval 5 sec)
02:44:17   (guide star SNR=2.8 X=1126 Y=824)
02:44:17   (first exposure estimate 5.38 sec)
02:44:27 **No stars at all found in guider image
02:44:27 **No usable stars this time, must be extremely weak, giving up.
02:44:27 **Autoguiding failed.
