<br>
I think there's some confusion here. This is what I see is going on :<br>
<br>
The 30 second timeout is just the default value in the exposure-timeout setting<br>
in the options of the focus tab. This part is fine.<br>
<br>
The question from Patrick is whether this timeout calculation should start at<br>
the beginning or at the end of the exposure.<br>
<br>
I think it should start at the end of the exposure, and thus we have a bug here<br>
that Patrick is willing to help fix.<br>
