Licensed to Arne Henden
01:56:45 This is AcquireScheduler V9.0.3
01:56:45 Custom image file path/names are in use
01:56:45   [PreFlip=300 PostFlip=300 AF=180 PU=60]
01:56:45 Hardware GEM pier side reporting is available.
01:56:46 Initializing AcquireSupport V9.0.3
01:56:46 Weather safe, server is Boltwood Cloud Sensor II
01:56:46 Telescope is ACP->TM61, driver V3
01:56:46 Dome is MaxDome
01:56:46 MaxIm DL is version 6.28
01:56:46 Imager is ASCOM
01:56:46 Using focus offsets and star mags from FilterInfo.txt
01:56:46 Selecting filter B from previous ACP run at 20240129@015531 UTC
01:56:46 Imager readout modes:
01:56:46   0 is Fast
01:56:46   1 is Normal
01:56:46 Guider is SX Universal (no rotator)
01:56:46 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
01:56:46 Max unguided exposure 60 sec.
01:56:46 Guider is set to multi-star mode
01:56:46 (assuring that FocusMax is running now...)
01:56:46 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
01:56:46 Calculated field of view (arcmin): H = 36.3 V = 24.3
01:56:46 Plate solving with GSC 1.1 (ok for wider fields)
01:56:46 Mount supports tracking rate offsets
01:56:46 ==== Starting target V838_Mon ====
01:56:46 ACPS Observation V838_Mon(1 of 1)
01:56:46   (belongs to Project AAVSO_P237_CWT_AUTO_ver3515, Plan V838_Mon)
01:56:46   (turning on sidereal tracking)
01:56:47 Pointing updates are enabled
01:56:47 Catalog Maximum Mag = 18.0
01:56:47   Start slew to V838_Mon...
01:56:48   (wait for slew to complete)
01:58:31   (slew complete)

01:58:31   Updating pointing...
01:58:31   Switching from B to SR filter for pointing exposure
01:58:31   Focus change of -320 steps required
01:58:35   (taking 10 sec. exposure, SR filter, binning = 4)
01:58:35   (using Fast readout mode)
01:58:35   (starting exposure)
01:59:00   (exposure complete)
01:59:03   (exposure complete and image downloaded)
01:59:04   Image finished
01:59:04   Plate-solve pointing image.
01:59:05   1951 image stars found
01:59:05   483 catalog stars found
01:59:06   Solved! 183 stars matched.
01:59:06   Average residual is 0.26 arcsec.
01:59:06   Pointing error is 2.777 arcmin @ angle 274.44
01:59:06   True focal length is 3466.7 mm.
01:59:06   True binned plate scales (arcsec/pix): H = 0.89 V = 0.89
01:59:06   True image center (J2000): 07h 03m 53.7s   -03° 50' 37.68"
01:59:06   Imager sky position angle is 178.7 deg.
01:59:06   [sync] pointing model updated
01:59:06   Re-slew to target.
01:59:06   Start slew to V838_Mon...
01:59:08   (wait for slew to complete)
01:59:18   (slew complete)
01:59:18   Target is now centered.
01:59:18   (high cadence option, no web previews)
01:59:18   (aggregated exposure times, trying to autoguide)
01:59:18   Switching from SR to SG filter for imaging
01:59:18   Focus change of 50 steps required
01:59:20   (take guider image at initial interval 5 sec)
01:59:30   Multi-star guiding, MaxIm chose star at X=590.9104 Y=714.8304
01:59:31   (guide star SNR=12.6 X=589 Y=709)
01:59:31   (first exposure estimate 1.19 sec)
01:59:36 ** This guide star disappeared or moved > 20 pixels. Can't continue.
01:59:36 **No usable stars this time, must be extremely weak, giving up.
01:59:36 **Autoguiding failed.
