Hi Helge, as far as I know current version of astroberry server has already a version of libgphoto2 that fixes the problem I found.
Check your version of libgphoto2 by typing this command in the terminal:

dpkg -s libgphoto2-6

I investigated further and it seems that libgphoto2 <= 2.5.23 suffer from a bug for Nikon camera preventing to capture images longer than 5s, this is fixed on 2.524 ( www.gphoto.org/news/ ). I then compiled from source the newest version of libgphoto2 and uninstalled the old one (without breaking the deps) and now the capure of a 30s shot seems to work fine.

I will update if further problems appear.

Hi, here attached the logs for a failed 30s exposure and a scuccessful one with 15s exposure.
I have also tried again with gphoto2 and this time it fails as well. I attach also that logs. I'm pretty sure that before it worked. I'm running astroberry on a Raspberry Pi3, and did few (official) update, I will try to revert on downloaded image and follow up.
Thank you.

Hi, I own a Nikon D3200 and unfortunatelly the Bulb mode it's not supported via USB, so I'm stuck with default exposure times unsetting the "force bulb mode" on the camera option.
The camera support shots wiht exposure times up to 30 sec. However if I try to caputer via ekos shots with exposure >=20 sec the capure fails. gphoto2 seams to work as expected if called with the option --capture-image-and-download. I think I traked the problem to the fact that the campera actually takes a bit longer than expected to perform the shot. In fact if I set 30 sec as exposure time the shutter remains open for about 32 second. Ekos starts a countdown of 30 secs and then tries to fetch the image before the actual capture finish. I asked a friend to measure the exposure time of another D3200, a D7200 and a D7500 and the results are consistent.
So I'm wondering if there is a quick/easy way to add a delay before the image fetch for solving the issue.

Thanks in advance
