02:56:58 This is AcquireScheduler V9.0.3
02:56:58 Custom image file path/names are in use

02:56:58 Hardware GEM pier side reporting is available.
02:56:59 Initializing AcquireSupport V9.0.3
02:56:59 Weather safe, server is Boltwood Cloud Sensor II
02:56:59 Telescope is ACP->TM61, driver V3
02:56:59 Dome is MaxDome
02:56:59 MaxIm DL is version 6.28
02:56:59 Imager is ASCOM
02:56:59 Using focus offsets and star mags from FilterInfo.txt
02:56:59 Selecting filter V from previous ACP run at 20240118@025607 UTC
02:56:59 Imager readout modes:
02:56:59   0 is Fast
02:56:59   1 is Normal
02:56:59 Guider is SX Universal (no rotator)
02:56:59 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:56:59 Max unguided exposure 60 sec.
02:56:59 Guider is set to multi-star mode
02:56:59 (assuring that FocusMax is running now...)
02:56:59 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:56:59 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:56:59 Plate solving with GSC 1.1 (ok for wider fields)
02:56:59 Mount supports tracking rate offsets
02:56:59 ==== Starting target TT_Ari ====

02:56:59   (turning on sidereal tracking)
02:56:59 Pointing updates are enabled
02:56:59 Catalog Maximum Mag = 18.0
02:56:59   Start slew to TT_Ari...
02:57:01   (wait for slew to complete)
02:57:37   (slew complete)

02:57:37   Updating pointing...
02:57:37   Switching from V to SR filter for pointing exposure
02:57:37   Focus change of -290 steps required
02:57:41   (taking 10 sec. exposure, SR filter, binning = 4)
02:57:41   (using Fast readout mode)
02:57:41   (starting exposure)
02:58:06   (exposure complete)
02:58:08   (exposure complete and image downloaded)
02:58:10   Image finished
02:58:10   Plate-solve pointing image.
02:58:10   126 image stars found
02:58:10   133 catalog stars found
02:58:11   Solved! 40 stars matched.
02:58:11   Average residual is 0.38 arcsec.
02:58:11   Pointing error is 3.657 arcmin @ angle 271.82
02:58:11   True focal length is 3461.5 mm.
02:58:11   True binned plate scales (arcsec/pix): H = 0.90 V = 0.89
