Hi all,
I'm trying to take some photo of M42 with my canon 5D mk3 using ekos.
If I click on preview after to have set all parameter correctly (exposure, iso and so on) some times I'm able to see correctly the photo and some times I see only a black frame...
While starting the sequence... all photos are a black frame....

For example I stared the following sequence all at 800 ISO:
2017-03-28T20:13:41: Starting 120 sec exposure
2017-03-28T20:11:30: Starting 120 sec exposure
2017-03-28T20:09:20: Starting 120 sec exposure
2017-03-28T20:08:09: Starting 60 sec exposure
2017-03-28T20:07:29: Starting 30 sec exposure
2017-03-28T20:06:03: Starting 30 sec exposure
But all raw files are black...

The strange is that opening, for example with gwenview, the cr2 raw files, I see that for all this images the exposure time is 1/10....

Where I'm wrong???
Please let me know
Paolo

Logs? Did you set BLOB mode in your camera? Manual Mode?

Hi Knro,
from log when I stared the sequence I had not errors...
But now, clcking on preview, I see:
2017-03-28T21:32:28: Starting 30 sec exposure

Yes, the camera is set to manual and in BULB mode.

I also activate the mirror lockup on camera and set mirror lock at 4 seconds under Indi Control panel

Regards
Paolo

Seam that I have some exposure problem... Now on Indi Control Panel the exposure setting is red and still to have the following messages:

Does this work?
Attach the gphoto2.log file

Hi Knro,
I'm using raspberry PI as Indi Server, so I'm using Kstars-Ekos from PC to pilot DSLR camera.
The gphoto2 command that you provided, I'll need to run it direcltu on raspberry or from my PC?

Thanks
Paolo

On the device attached to your camera, so the Pi.

Very good!
I'll try later when I'll come back to home....

Stay tuned
Thanks for now

Paolo

Hi Knro,
I performed gphoto2 command and from command line it is terminated with the following :

# gphoto2 --auto-detect --debug --debug-logfile=gphoto2.log --capture-image-and-download
Model Port

---

Canon EOS 5D Mark III usb:001,009
ERROR: Failed to capture the image.
ERROR: Failed to capture

In attach the log file.
Thanks in advance
Paolo

Well, you're using 2.5.9, can you upgrade the latest libgphoto2 version? This is a gphoto issue, not INDI. I would it suggest you open an issue at libgphoto2 Github issues page with the log attached.

Hi Knro,
I updated the libgphoto to the latest version but the issue persist....
The strange is that also with my old 50D I have the same issue.

But I'm only one to have trouble with canon DSLR?

Perhaps I found the issue But I'll need to test tomorrow
