Exposure time and ISO issues with Fuji XT3

Exposure time and ISO issues with Fuji XT3 was created by Raul

Hello all,
I have bought a Raspberry Pi 4 three days ago and installed Astroberry on it. I am deeply impressed by how powerful it is. I have had a few glitches that have been all solved with the help of this forum and google.

I am managing now to connect my Fuji XT3 and did a few captures, managed to change settings like aperture, shooting mode, metering , etc. It looks very promising but I have the few issues that might be a show-stopper.

1. When I set the exposure to a value, the exposure value on the camera differs by 100. For example if I set Exposure to 200, I will get 2". The problem is that the counter waits 200" to take the next picture (!).

There are a lot of places to define Exposure. On the main Capture settings menu but also on the Indi Control Panel under "Main Control", which says Expose Duration (s). Also the same occurs with Presets unsurprisingly.

EDIT: Did find this thread with the same issue but no answer. The answer on the link didn't help me

2. I can not manage to find a way to make the ISO selection drop-down show. I am using the GPhoto CCD profile, and shooting in FITS Format. Next to the FITS dropdown, there is an empty space where I believe ISO should appear.

3. If i use RAW, I can only achieve pictures using Native Transfer Format when triggering from the "Main Control". As soon as I trigger from the CCD & Filter Wheel menu, it reverts to FITS and I get an error saying "Unsupported Bayer pattern GGGG".
The only work around is shooting JPEG which is far from ideal.

Any help will be greatly appreciated.
Many thanks

Found the issue with the black and whitr pictures. It was that I needed to activate 3D Cube in the EKOS options under the FITS tab.

ISO did appear once I updated and upgraded INDI. I have downloaded Astroberry recently so thought it would be up to date... wrong. Glad it appears

It still for some reason the Image Info tab keeps changing to some weird values every time i take a picture even though I reset them before... one of them is the bayer Filter changing it to GGGG.

More than two days later I have found the link below…
indilib.org/forum/ccds-dslrs/5682-issue-...-using-fuji-xt2.html
Same issue here, I can see the Shutter Speed changing, but always being Exposure / 100, ie: i set exposure to 10", SS is set to 1/10.

If it helps to anyone, I found it more stable after changing the sensor resolution to 6240x4160.
I was using DIgicam's sensor resolution which is back-calculated from sensor size and pixel size... www.digicamdb.com/specs/fujifilm_x-t3/

Below you can find the logfile and Gphoto settings I used for a suposedly 60" exposure.
Picture looks well exposed and on the camera I could see a Shutter Speed of 1/1.6. EKOS took 60" to take the picture anyway.

Gave up and bought a Canon 450D which is working flawlesly. Its a shame because the XT3 is a much better camera in terms of ISO (iso invariance and max iso) for a tradeoff of a smaller pixel.
Hope someone finds a solution to this eventually.

Hi everybody,
i' am new to this forum and to astrophotography too.
I have also use Fuji xt-3 over kstars-ekos and i have a similar problem with exposure.
Specifically when i create a sequence and set the exposure, to lets say 300 s and start the sequence, the progress start to count the exposure time (300 s) and after that time the shutter close....

Has anyone here had success getting their X-T3 or X-T4 to expose correctly in Ekos? I'm getting exposures with my cameras up to and including 60 seconds forced to the pre-defined exposure times in the camera (like the T mode times), but I cannot get the camera to expose anything longer than 60 seconds. This is painful. Using StellarMate OS on an RPi4/4GB/Model B and the most recent stable builds of Kstars/Ekos.
