Summary0001983: Unable to do flats via capture tool
I prepared to do flats and get some strange error.
I wanted to do flats without the help of a sequence, only use the capture tool. The tool does the following, it finds the exact exposure time, but than it does not do flats at all.
It it shown in the log. A restart of ciel does not help.

Flats with a sequence work well.

In the log it say it reach the minimum exposure time you configure, but the flat is still saturated with a mean level of 65504.
So it abandon the procedure because it need a shorter exposure time but it cannot.

What are your setting for min/max exposure time and flat level in this page :

No problem.

I remark an inconsistency with this message send only for sky flat, but panel flat continue with the wrong image level.
It is probably better to also stop to adjust the panel power or the parameters.
