I took a sequence of 2 frames exposure of 1s delay 2s FITS format.
The first frame is vizualised in the FITS viewer. I looked at the statistics and found a mean of 525.
For the second frame the colors change and the mean becomes 12.581. The two frames are saved and I have attached them.

I was not yet there, but indeed I do not understand the view in the FITS viewer. If I take 2 frames, I expect that I get twice the same view but that is not the case. The intensity seems to change from one to the next frame. The viewer is not adding I think but need to look closer into it.
In the meantime in order to analyse the issue I reconnected my ZWO camera that worked fine months ago. Now I can launch the driver and start a sequence but it loops without end and without vizualising the frame. I do not understand what is happening. I use the FITS format. From the other side, I thought something was wong with my camera but under windows it works fine.

Here follows the result of my verified test.
The gphoto2 version gives the following result:
This version of gphoto2 is using the following software versions and options:
gphoto2 2.5.9 gcc, popt(m), exif, no cdk, aa, jpeg, readline
libgphoto2 2.5.16.1 all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.12.0 iolibs: disk ptpip serial usb1 usbdiskdirect usbscsi, gcc, ltdl, USB, serial without locking

I used the Pentax DSLR driver
After reboot and launch of kstars I launched indi and connected the DSLR.
I created a first sequences 2 times a 2s exp, 0s delay with FITS format ISO 100 followed by a sequence with 2 frames with 2s exp and 0s delay again with fits format and ISO 800.

I started both sequences and it all went well except after the 3rd frame the ISO value went temporarelly 1600 before again returning to 800.

Find attached the log

If you want I will check again this evening. I was first running tests with one line of 2 exposures in the sequence list. I deleted the line and put a new one with another ISO value and the ISO did not change on the DSLR. Another test was running two identical lines with only the ISO value that was different. I do not remember whether I run the tests with the FITS format or the Native format. I have the impression that performance is better with FITS than with native. Do not put too much time in it now. I will come back this evening with verified tests and provide the logs.

I just tested the Pentax DSLR driver.
For the logging I selected Ekos Capture and FITS and the CCD-driver (See log attached).

I created one sequence of 2 shots with exposure 2s/2s delay and started with ISO 3200. Next I deleted the sequence and just changed the ISO back to ISO 100.

The viewer shows the frame at ISO 3200 and does not change the ISO while the sequence has ISO 100. I am pushing the start sequence button rather than the Preview button. The result is that the viewer pops up and allows me to invert colors, save or close. The behaviour is totally under control if selecting the FITS format. Frames get saved properly. Also the communication of new parameters for a new sequence seems to work well with the FITS format. Issues reported before were probably due to the native format viewer.

Good question. Does that mean that today beside Canon and Nikon DSLR drivers we have now also a Pentax DSLR driver?

Sorry Jasem, here it is.
After some reflection, during the execution of a sequence, the frame is shown in the viewer leaving the option to save or not, but the dialogue does not wait until you reply. As a consequence, frames are not saved at all. Is this normal? I have not understood why watching a frame in the viewer is not an option. When you do not take the option, frames are just saved in a predefined directory.

I upgraded before starting and must state the the situation is more stable.
Two sequences have been defined with different ISO. The first sequence works fine but the frame is showed in the viewer before the next frame is taken. I have the impression the frames are not saved. After the first sequence, the ISO setting has been changed and communicated to the DSLR. This did not work before. The second sequence is launched but no frames are shown in the viewer.
This time I attach the log.
The gphoto2 version is as follows:
gphoto2 2.5.9 gcc, popt(m), exif, no cdk, aa, jpeg, readline
libgphoto2 2.5.16.1 all camlibs, gcc, ltdl, EXIF

I installed gphoto2 and it came with the following versions:
gphoto2 2.5.9 gcc, popt(m), exif, no cdk, aa, jpeg, readline
libgphoto2 2.5.14.1 all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.12.0 gcc, ltdl, USB, serial without locking

I had the impression that all was more stable after having run the sudo apt-get install gphoto2, but just before writing this reply the camera was hanging again.
I created 2 sequences to be run one after the other. The first was 5s exposure with ISO 800 followed by 1s and ISO 1600. Running one after the other I heard the 5s mirror flipping and the 1s mirror flip but the ISO setting did not change and remained on 800. Further I also noticed that the frame displayed after changing the ISO was the last frame taken and not the new one taken with the new ISO value. Could it be that the buffer is not emptied?

I probably have found the issue. Previously the DSLR was in manual mode. Have now put it on "B" (Bulp) mode and the PC takes control and the frames are transfered as it should.

Once the Sequence is in the Aborted or Completed status and taking a frame manually, the frame is transfered to the Linux PC and shown in the viewer. So Indi does not trigger the camera. Is there something wrong with the settings?

I connected my Pentax K-5 via USB to my linux machine, set USB to MSC and I see the PC communicating with the DSLR. When running KStars and EKOS I launch the GPHoto DSLR driver. When taking a frame I see the camera taking the frame but do not hear the mirror flipping. ISO is set as requested but "Capture failed" and he starts over trying again.

When connecting indiserver I get the warning: " [WARNING] Shutter speed widget does not have any valid data (count=0) " and have not found what this means.
Could someone help me out please?
Regards,

Stefan

Never tried installing KDE? MATE runs fine but I continue having the issue with the missing "Minimise" and "Maximaise" buttons.

Would it be possible to run kde instead of mate? Under the latter there are some minor issues with window buttons not being present at all. Appart from that I am very satisfied with Mate, but kde I do not get running. Any hint or experience ?

I am not using a laptop to connect via vnc to the Pi, but a tablet. My main reason is its battery autonomy (tablets indicate and compete just about this point while laptops do not always refer to the battery capacity). On top a tablet does not need a keyboard and mouse as indipendent components. Software keyboard and mouse are usually available via the vnc client. I run now everything on a 10.5" Samsung Tab S and Remote Ripple as vnc client. The bigger the screen the better. I am very happy about the result. I now abbandoned the idea about multiple RPi interconnected via wifi. I confiscated an old router and connectmy machines via 1GBps cable connections. The tablet just shows the screen over wifi and thatis fine. My router is wireless bridged to my home network when available. What would be interesting is that if the provider wifi network is availabe the router could bridge to the provider network instead of the home wifi. This issue is not really an astro one so it should may be discussed elsewhere.

regards,

stefan

Jasem,
I followed your suggestion and tried to install ubuntu 16.04 server for RPi2 and added kde as KUBUNTU-DESKTOP from scratch.
It is not an EKOS issue, but could you point me towards making the buttons at the top-right (close the window, minimise the window and maximise the window) visible?
With KDE I do not have any button but clicking with the mouse cursor in the top right corner closes the window, so the button function is implemented but I do not see the icon.
