With that the option is here - see also the Screenshot that I have attached.

So first I have to say thank you at least 1000 times

There is just one more issure: The maximum exposure time seems to be 10000 (may be 1 second) but the Rasperry Pi Camera supports up to 6 seconds. On the first page I can enter different values for "Expose" but they seem to make no real change. On The V4L2 Control Tab is also a value where you can enter times up to 10 000 (see also my second attached screenshot). That's acutally pretty bad because even ISO 800 and 1 Second may not be enough for some needs of Astronomy.

That value may come directly from V4L2 because that L readout gives me also:
exposure_time_absolute (int) : min=1 max=10000 step=1 default=1000 value=10000

There was also a thread about the problem (but only one entry) which also had the idea that the problem may be V4L2 related (what might be pretty bad I thing).

Thanks,
Dominik

Ps: Thanks for developing the solution !
