Licensed to Arne Henden
02:55:38 This is AcquireScheduler V9.0.3
02:55:38 Custom image file path/names are in use
02:55:38   [PreFlip=300 PostFlip=300 AF=180 PU=60]
02:55:38 Hardware GEM pier side reporting is available.
02:55:39 Initializing AcquireSupport V9.0.3
02:55:39 Weather safe, server is Boltwood Cloud Sensor II
02:55:39 Telescope is ACP->TM61, driver V3
02:55:39 Dome is MaxDome
02:55:39 MaxIm DL is version 6.28
02:55:39 Imager is ASCOM
02:55:39 Using focus offsets and star mags from FilterInfo.txt
02:55:39 Selecting filter SG from previous ACP run at 20240504@025502 UTC
02:55:39 Imager readout modes:
02:55:39   0 is Fast
02:55:39   1 is Normal
02:55:39 Guider is SX Universal (no rotator)
02:55:39 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:55:39 Max unguided exposure 60 sec.
02:55:39 Guider is set to multi-star mode
02:55:39 (assuring that FocusMax is running now...)
02:55:39 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:55:39 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:55:39 Plate solving with GSC 1.1 (ok for wider fields)
02:55:39 Mount supports tracking rate offsets
02:55:39 ==== Starting target OJ287 ====
02:55:39 ACPS Observation OJ287(1 of 1)
02:55:39   (belongs to Project AAVSO_MISC_PYG_AUTO_ver3260, Plan OJ287)

02:56:15   Switching from SG to SR filter for pointing exposure
02:56:15   Focus change of -50 steps required
02:56:18   (taking 10 sec. exposure, SR filter, binning = 4)
02:56:18   (using Fast readout mode)
02:56:18   (starting exposure)
02:56:40   (exposure complete)
02:56:43   (exposure complete and image downloaded)
02:56:44   Image finished
02:56:44   Plate-solve pointing image.
02:56:45   373 image stars found
02:56:45   211 catalog stars found
02:56:46   Solved! 79 stars matched.
02:56:46   Average residual is 0.31 arcsec.
02:56:46   Pointing error is 4.689 arcmin @ angle 274.18
02:56:46   True focal length is 3468.3 mm.
02:56:46   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
02:56:46   True image center (J2000): 08h 54m 29.0s   20° 06' 51.02"
02:56:46   Imager sky position angle is 178.8 deg.
02:56:46   [sync] pointing model updated
02:56:46   Re-slew to target.
02:56:46   Start slew to OJ287...
02:56:50   (wait for slew to complete)
02:56:54   (slew complete)
02:56:54   Target is now centered.
02:56:54   (high cadence option, no web previews)
02:56:54   (aggregated exposure times, trying to autoguide)
02:56:54   Switching from SR to B filter for imaging
02:56:54   Focus change of 320 steps required
02:56:58   (take guider image at initial interval 5 sec)
02:57:11   Multi-star guiding, MaxIm chose star at X=1111.308 Y=218.0119
02:57:11 ** This guide star disappeared or moved > 20 pixels. Can't continue.
02:57:11 **No usable stars in guider image; trying again at max guider exposure
02:57:24   Multi-star guiding, MaxIm chose star at X=912.8956 Y=459.0268
02:57:25   (guide star SNR=36.4 X=913 Y=459)
02:57:25   (first exposure estimate 1 sec)
02:57:30 **No stars at all found in guider image
02:57:30 **No usable stars this time, must be extremely weak, giving up.
02:57:30 **Autoguiding failed.
