BTW, why is it necessary to first switch on tracking before tracking a target? I also experience that with OnStep. I always wondered if I have configured something wrong (Running a DIY mount with OnStep control).

Ah, thanks a lot. I have never looked at the Focuser tab, as I do not have a motor focusser (yet).
Yes, that does what I was missing. I therefore withdraw my request! :-)

OK, maybe I got the wrong impression. When auto-stretch was applied I cannot un-apply it and also the histogram now shows the new pixel values. From that I wrongly deduced that the original pixel values were changed.
I was used to the Siril GUI, which uses a drop down menu where you can choose between "Linear", "Logarithm", "Square Root", "Squared", "Asinh", "AustoStretch", "Histogram". Here you can always go back to "Linear".

To be more precise: When I open a FITS from Kstars and the EKOS option "FITS" -> "Auto Stretch" is set, I cannot get back to the unstretched view. Or at least, I did not find a "reset" button in the FITS viewer.
Yes, there is an "Undo", but only for manually applying "View" options.

Well, my proposed improvement would then be to add an "Original" or "Linear" to the list in the "View" menu, which should revert the view to the original, linear image.

I am not sure if this request belongs here or somewhere else. The FITS viewer seems to be an integral part of Kstars.

I observe several issues with the current FITS viewer:

1. Any changes to the image representation actually changes the data and cannot be made undone. E.g. doing an auto stretch. I would prefer to never change the actual image data, but only apply changes to the view, e.g. auto-stretch, various stretch options. E.g. Siril does it this way.
2. Remember the last viewing settings (e.g. auto-stretch, log) per camera. Currently, when applying auto-stretch in a sequence, it is reset to default when the next image is loaded.
3. FITS viewers in different tabs should be allowed different independent settings. I would like to switch off auto-stretch for the Camera tab, but enable it for the Align tab (to see how well stars are being seen).

Or is there a possibility to use an external FITS viewer?

Maybe I am using it wrong. Any thoughts, suggestions?

Yes, there is a live video, but that sometimes requires a different setting (e.g. ZWO ASI 224mc needs Luma mode) or is not available at all.
It would be nice to have a repeating image acquisition (with the current settings of the Ekos Camera tab) just to show what the camera is seeing. I would need this for manual focussing and aligning the guiding camera to the main telescope.
I currently use the "loop" of the Ekos Guiding tab for that, but I would prefer to have a live view button next to the live video in the Ekos Camera tab.

Guido Muesch replied to the topic 'VNC Desktop does not resize' in the forum. 3 months ago

Hi Radek,

Yes, thanks. I've figured that out already. :-)
My laptop has 1600x900. I tried local scaling now. A bit blurry and small, but bearable. Working with Kstars/EKOS is anyway a bit on the edge with a "small" display.

Thanks for explaning why you have chosen x11vnc. It would have been my next question. :-)

And my appreciation for your work and effort on putting Astroberry together!
Until now I used a RasPi with Ubuntu Mate, which I had setup according to some information I found here. But it lacked a lot of features you have built into Astroberry. I like the noVNC part and the VAP setup.

No, it's not related to -xrandr.

Well, I shot myself in the foot!

I did not realize that x11vnc just makes the current running X server available via VNC. And because I had issues with HDMI and overscan when I connected Astroberry to my monitor, I removed the HDMI entries from /boot/config.txt. Now, when booting without an attached monitor it seems to fallback to a very small screen resolution.

In my defense, I used a Raspberry Pi before where I had setup a standalone vncserver, not being connected to an actual running X server. This one had the ability to be resizable to whatever the VNC client requested. Quite convenient when the vncviewer was running on a laptop: sometimes with the small laptop display and sometimes being connected to an external monitor.

I have to think on how to achieve this again.

I started trying out Astroberry, installed the image and did a system update.
I did this connected to a real monitor, kbd, mouse.

Now I connected via VNC for the first time (via browser and VNC client), but I only see a tiny VNC Desktop (656x416), which does not resize.

I see those processes running on astroberry:

1422 ?        Ss     0:46 /usr/bin/x11vnc -xkb -noxrecord -shared -forever -nowf -repeat -display :0 -auth guess -rfbauth /etc/x11vnc.pass -o /var/log/x11vnc.log
1423 ?        Ss     0:00 bash /opt/noVNC/utils/launch.sh --listen 8080 --vnc localhost:5900 > /dev/null 2>&1

I wonder if the "-xrandr" option would help, but where can I find the x11vnc configuration?

Guido Muesch replied to the topic 'Video Astronomy like viewer (Live Stacking)' in the forum. 4 months ago

Sorry, I have not done much in this direction anymore as I had a lot of other distractions. E.g. currently I am building a GEM with OnStep control.

One year ago I experimented a bit with Python and Kivy (a GUI framework). I wanted to keep it pure Python so I used the INDI protocol implementation from sourceforge.net/projects/pygtkindiclient/ as a starting point. One reason to choose Kivy as a GUI was the idea to also port it to Android. However I got stuck because Numpy was not working with Python 3 on Android at that time.

Unfortunately I can confirm that the Raspberry Pi version crashes as well since a couple of days.

Thanks. Also interesting, but I would like to stick to my pure Python client.
Currently experimenting with Kivy it could potentially run under Windows and Android as well.
