Thanks Jasem!
This seems to be a common issue with KDE - while researching this issue, I found a lot of people complaining about the same issue with konsole.
I think this issue is really with Gnome, but workaround with desktop file is too simple :-)

Alex Varakin created a new topic ' Kstars Integration issue with Gnome desktop' in the forum. 3 weeks ago

Hi,
Kstars has a problem with adding to favorites in Gnome desktop. I am running 2.9.6 on Gnome edition of Manjaro.
I was able to fix this issue by adding:
StartupWMClass=kstars
to /usr/share/applications/org.kde.kstars.desktop
It would be nice if the original package would also get this fixed.

Alex Varakin replied to the topic 'Driver OnStep (LX200 like) for INDI' in the forum. 3 weeks ago

I am currently using azwing's private INDI branch for running my system because with the code in the main branch KStars does not see ONstep focuser. I was wondering when this branch will be merged into main branch? Do we need to do more testing? I can help with this.

Alex.

How about PEC data? Arent we moving it back and forth between device and client?

Around one week ago it was good. BTW, I also had an issue with compiling some other 3rd party driver, I think it was apogee.
We can probably try to use git bisect command which finds a bug using binary search:

Hi Ray,

I could not find the clock icon you are referring to. Where is it?
I was also thinking about getting a RTC too, this should be useful for imaging at a remote site with my RPi which does not have clock. Is it possible to attach GPS to Onstep as a source of accurate time?

Some of them are in the main repo like KStars but rest are in AUR.

Khalid, Are you doing Astro Photography at night? If so, CCDCiel is a great match for CDC. It runs the camera, focuser, plate solving etc.

Alex Varakin replied to the topic 'Driver OnStep (LX200 like) for INDI' in the forum. 4 weeks ago

Hey Khalid!
ccdciel is a lesser known software by Patrick Chevalley, who also wrote CdC. It is similar to Ekos and is intended for imaging. I run my setup under Linux using INDI, ccdiciel for image capturing and CdC as a planetarium. I tried using Ekos few times but had weird issues, on the other hand ccdciel is extremely stable for me.
Thank you for confirming that Ekos has a feature to sync the clock. I filed a feature request with ccdciel about having the same feature in ccdciel, but then I thought that maybe this feature shoudl be in the INDI driver so that all clients can get use of this feature.

Another question I have is about focuser - looks like only the private branch in github has the code which allows the focuser to be visible in KStars. The public release does not have this feature yet. What is the plan in terms of merging this code into the public release?

Alex Varakin replied to the topic 'Driver OnStep (LX200 like) for INDI' in the forum. 4 weeks ago

I ran into an issue with Onstep and ccdciel combination where clock of onstep is not initialized with current clock of PC. As a result, mount positioning is totally off. Interestingly KStars does not have this issue - it seems to be sending the currend data/time to Onstep.
Initially I thought that the fix should be in ccdciel but later changed my mind and am thinking that maybe this should be fixed in the INDI driver. Maybe more conservative approach would be to have a button somewhere in the INDI control panel which would allow user to initialize the date/time manually.
What are your thoughts?

Alex Varakin created a new topic ' Setting up astro software under Manjaro (or Arch) Linux' in the forum. 4 weeks ago

Hi,

Manjaro distribution is currently becoming one of the most popular distributions. According to Distrowatch, it is the most popular distribution and for a good reason: it is very easy to install, provides access to very recent packages and at the same time it is pretty stable. I am running it for about a year and am very happy so far.
So I decided to try to setup all the astronomy software I use under Manjaro. It turned out pretty simple once I figured out few issues. I wrote a script which should do the whole thing without much effort. It installs KSstars/Ekos, PHD2, astrometry, ccdciel, SkyChart, indi and sextractor (which is highly recommended to help with plate solving).
Here is the script:

sudo pacman -Syu
sudo pacman -S --needed kstars breeze-icons yaourt arduino binutils patch cmake make libraw libindi wxgtk2 gpsd gcc

yaourt -Sya --noconfirm ccdciel
yaourt -Sya --noconfirm libindi_3rdparty
yaourt -Sya --noconfirm open-phd-guiding-git
yaourt -Sya --noconfirm skychart
yaourt -Sya sextractor-bin
yaourt -Sya astrometry.net

wget broiler.astrometry.net/\~dstn/4100/index-4107.fits
wget broiler.astrometry.net/\~dstn/4100/index-4108.fits
wget broiler.astrometry.net/\~dstn/4100/index-4109.fits
sudo mv index-410[789].fits /usr/share/astrometry/data

Please let me know what you think.

Alex Varakin created a new topic ' Ekos unable to connect to phd2' in the forum. 6 months ago

I am running the latest bleeding version of KStars and Ekos.
Ekos is unable to connect to phd2 because looks like INDI profile does not save the port of phd2.
I enter port number 4400 and save the profile, but then I open profile for editing again, I see port as 0.
Obviously Ekos is unable to connect to phd2 with port 0 and thus connect fails.

Alex Varakin replied to the topic 'New INDI client CCDciel for astrophoto sessions' in the forum. 2 years ago

I have done a couple of successful sessions with ccdciel running on RasPI 3 and so far I am very happy with how it works.
I like that it has very simple interface with just one window and image preview is in the same window.
The best part is that so far it is very stable and has not crashed a single time, whereas Ekos/Kstars were crashing every session.
I also like that it integrates nicely with SkyChart and at the same time it is not one huge monolithic program.

I ran into issues with plate solving, where for some reason ccdciel was incorrectly guessing resolution scale due to binning, which was causing plate solving to fail.
For now, I resolved this problem by getting the source and compiling it after changing it to do blind solving without all the optimizations.
Also internal star detection algorithm was not very good at detecting stars for different images I used for plate solving, which I solved by providing parameter --use-sextractor.
After these two changes were done, plate solving works very reliably and fairly fast - about 30 seconds in total.

Patrick,
If you are reading this, congratulations on creating a great image capturing software, which does not try to do everything but does one task very well!
Also, I think that allowing user to select blind solving and addition of --use-sextractor to parameters would greatly help with improving reliability of plate solving.
I started working on enhancements, described above, if you are interested in incorporating them into project, I can provide a patch.

Alex Varakin created a new topic ' Problem with guiding calibration' in the forum. 2 years ago

I am having intermittent issues with guiding calibration using internal guiding, where mount does not receive calibration signals.
It happens once in a while, approximately 1/3 of sessions. It is "fixed" by restarting kstars.
I do not see any messages in the log window of mount during calibration when I have this issue. If calibration works, then I see messages.

Here is my equipment:

Atlas via EQMOD
ST8300M CCD
DIY Arduino focuser
SX filter wheel
DSI guider
10 port powered USB hub
Ubuntu 16.04
Kstars version - 1 week old build from source

Alex Varakin replied to the topic 'Now the offline plate solver is not working for me' in the forum. 2 years ago

What happens with new builds of astrometry if --no-fits2fits is passed - does it crash?
As a workaround, would it be possible to allow user to configure command line params for "Load and Slew"?

Alex Varakin replied to the topic 'Now the offline plate solver is not working for me' in the forum. 2 years ago

I had exactly the same issue.
I fixed it by adding --no-fits2fits to command line.
In my case I had the issue with "Load and Slew" which does not have settings for configuring the command line, so I had to change the source code and recompile the program.
I am glad that I spent a cloudy night fetching the source code and compiling the program, so fixing this issue took few minutes this clear night B)
