Problems: 

8 UT Suddenly CTIMAC4 frozen, crashed.  Fails to restart. It feels hot. Wait ~ one hour, it starts.

As described in the comments, there might be a problem with the instrument's shutter, or something else.

Comments: 

DIMM worked ~ first hour (it was a windy night and then overcatst.)

HIP072875, file 1116, few counts. A 420[s] ok, so added a new 900[s] exposure.
Files 1128 and 1130, no structure ('T0I-4365' and 'RU Lup'.) Instrument's shutter?
Repeated integration for 'RU Lup' but, same result. 
Rebooted OPTGUI. Found DHE issues, new reboot, ok. A ThAr test lamp (file 1133) is ok though EM did not printed counts to the header (restarted the EM.)
Repeating integrations for 'TOI-4365' and 'RU Lup': ok!
TIC0312030014 file 1142: at 03:30 UT, cloudy. 05:30 UT, closed dome shutter.Overcast.
