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

This package is for Pi3. Would it also work for Pi2?

Happy to hear about this evolution. I look forward to have the ppa running again. I will check this weekend and keep you posted.

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.

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.

Excellent. See there are a few settings I was not aware of and affecting my situation.
Thanks.

Thanks Jasem, I will check as you suggest and as far possible. The binning and the logging I will do straight away. I suffer from a lot of light pollution and think I need to buy a clp filter.
As far as alignment is concerned, my setup is not a fix one, so I need to repeat the alignment every night I take my gear out. I have never done it so I need to learn.

Could you confirm that I need to stop tracking in the control panel before being able to start guiding on 2 axes, is tha all done via the log enabling? That would surprise me, but it all depends how the system works, of course.

Regards,

Stefan

I have just connected the ST4 cable. Still not calibrating. It is the Declination axis giving problems.
But I think I found the reason. I listened to the mount and it was whispering as it usually did. It was tracking.

I went to the control panel and switched of the tracking by clicking slew. Going back to the guiding tab, I started calibrating and now it is working. Calibration of the two axis is fine now and when guiding it locks on 10" at the Y-axis.

My conclusion is that when starting the guiding, the tracking is not switched off. Good to know but not evident.

Will take a few pictures and see what the result is.
Time to go to bed. I will report back tomorrow evening if the weather is OK (forecasts are good anyway). Thanks a lot for the assistance :)

OK, now I understand.
What is the difference in performance? I have an ST4 cable but if it works well via the USB why using another cable.

In any case the calibration seems not to work as far as the GUI explains.
I have now observed the system's behavior and the guiding hooks off after 9min.
I have no selected the Via EQMOD Mount and I cannot say it works well.

Hi,
After being able to do off-line resolving with astrometry.net I try the next challenge. GUIDING

Capturing picture is fine.
First I did capture and resolve until the picture was within less than 30 arcseconds in the center of the image.
Under EKOS guiding the brightest star is still in the center. I try to have a box of 64 pix wide in order to be sure that the star can move in the box and return to the center.

After capturing, I start calibrating.
When the system arrives at 100% I get a message popping up stating: Guide RA: Scope cannot reach the start point after 30 iterations. Possible mount or drive problems.

I un-check the 2 axes check-box and repeat the procedure. Now it gives me the same message but after 12 iterations.

I have selected as guiding camera the ZWO ASI 120MC as only possible option.
For VIA I have two options, or the ZWO camera or the EQMOD mount. I tried both but no difference.

Is there really something wrong with my mount?
How is it than possible that the capture and resolve function with GOTO slews my scoop to the star so fine in the center of the image. How should I interpret this?

Thanks in advance for the help.

Stefan

Thanks a lot for the info. Are you also reading GPS position information for updating the Geo-settings in KStars? I am a bit worried about the fact that positioning and timing use different settings of the GPS module and it seems that the positioning setup disables the PPS signal. As I already mentioned, during the observations the position does not change, and the GPS module can be put directly in timingmode.

Hi, Patdut, I confirm your finding. Also I saw yesterday with the last upgrade KSTARS crashing when I stoped the Indiserver.

I am also going to integrate a GPS module in my setup, and I am surprised to see discussions about writing drivers.

After reading some doc of the gps module, I saw that the pps signal is disconnected when one reads position data. I would read some time position data just for averaging the noise on the position information. Once position is stable, and because I am not moving my setup, I do not need to measure the position anymore. I would at that moment switch to timing, so that the pps signal is again active.

For timing I would integrate the gps in a dedicated RPi, configured as stratum 1 ntp server. Via the OS and the ntp protocol, the clock of my machines on the network are synchronised, and also ekos and kstars will see and use this correct time or not?

As such my only problem is to read the position in Ekos. I was hoping to use the arduino integration for this.

May I have your views on this way of working?
