Nikon J3 exposure settings in Ekos? #422

Describe the bug BULB vs defined exposure times A clear and concise description of what the bug is.

Name the camera If this is camera specific, include the camera name as shown by gphoto2 --auto-detect or USB IDs Nikon1 J3

I have a Nikon J3 camera, which I want to use as a DSLR in Astroberry (INDI/Ekos) for astrophotography. I only can make captures with the INDI-setting: Force BULB = off. But I can not define exposure times in Ekos because INDI Control Panel says: "Exposures shall utilize camera predefined exposure time before attempting BULB". Of course, I want to set up exposure settings in Ekos. Now it is not reacting on defined exposure times, it seems to be taking always captures with a predefined exposure time. In Astroberry (Ekos), I made a setup with the selected device: Nikon DSLR. I understood that the driver is based on gphoto2. What can I do to solve this problem?

libgphoto2 and gphoto2 version output of: gphoto2 --version Latest version in Astroberry (I think) To Reproduce Steps to reproduce the behavior:

If its a camera misbehavior, attach debug output using --debug --debug-logfile=debug.log (if considered useful).

in which exposure mode is the camera? does it help if the dial is on Tv (Or whatever Shutterspeed prio is)

does the gphoto2 commandline tool show shutterspeed and allows to set it?

The J series might not be that reliable.

I am having the same problem with the Nikon 1 J3. It takes pictures but only with a short exposure time. In Ekos, when I select 10s exposure times, I can hear the shutter sound twice with less than a second between the two shutter sounds. Ekos continues to count down to 10s and after 10s, the image is downloaded. But the exposure time is not 10s but less than 1 s.
