FWIW, in a Bookworm Raspberry Pi OS aberration inspector crashes Kstars all the time and the way around it is to launch Kstars from the command line first setting XDG_SESSION_TYPE=x11.

John,
Success, although I also changed the step size to 500. Thanks for your help!

John,
Thanks again. Yes that was going to be my next step, uncheck everything. I will check it out (bad pun) the next time I am under the stars.

I have lots to learn about using your Auto Focus tool, but what I have used so far has been working great for establishing a good focus.

Thank you John for this tool: it replaces Hocus Focus for me. What about adding the labels for Camera and Telescope too? Sometimes I forget where is the correct side and have to listen your video youtu.be/IbbxJJS9W48?si=r3TkxJdIpM7hODd_&t=835

If it helps, this is what ChatGPT had to say on the subject:
The issue seems to be related to the use of the super keyword within the Package class. The error message "type object 'super' has no attribute 'install'" indicates that Python is unable to find an install method within the superclass of Package.

In Python, when you use super() without arguments inside a class, it is typically used to call methods from the superclass. However, in your Package class, there is no superclass method named install, which is causing the error.

To resolve this issue, you have a couple of options:

Override the install method from the superclass: If CMakePackageBase defines an install method, you can override it in the Package class and provide the necessary implementation.
Ensure the superclass has an install method: If CMakePackageBase does not define an install method, you should not attempt to call super().install() in your Package class.

Make sure to review the superclass (CMakePackageBase) to see if it defines an install method. If it does, you can override it as shown above. If it doesn't, you'll need to remove the super().install() call and implement the install method according to your requirements.

It turned out to be much more work than I expected to get the R-Pi version working. CloudWatcher on the Mac uses scripting for many features which, in an INDI environment, will be handled directly by a client. So I've stripped them out, which removes a potential major headache oil porting.
But, it's been in development for well over a decade and uses various things which are now defunct, or were never available on R-Pi (these are mostly to do with preferences, of which there are hundreds). So I've had to rewrite quite large bits of it. Now it's working, but it still has the GUI peculiarities which will need tuning and adjustment. So, a work in progress, but, there is progress !

Welcome to the forum, Nathan!

I have built a very simple pan-tilt Controller for my weather camera. Maybe its code is helpful for you: pan_tilt_controller.py

Howdy all,

I do Radio Astronomy at home using a custom built 1 meter antenna. I am experimenting with drives and controls to eventually add tracking capability to my scope. I 3D printed a slew drive which had good results moving the scope in elevation; I suspect it will do even better in azimuth based on my testing.

docs.google.com/presentation/d/10aHnodI9...7&rtpof=true&sd=true

I am using the Waveshare motor hat to manually drive the motors but would like to integrate with KStars, Stellarium, or the like. I have reviewed some projects already, and other literature (like Radek's github.com/rkaczorek/astroberry-diy, and Kevin's www.indilib.org/forum/focusers-filter-wh...or-raspberry-pi.html), but they seem focused on focusers (ba-dump). Also I've read that the microstepping has been a concern.

However, for my application pointing errors are not critical as my beamwidth is so large. Can anyone offer any help on how to modify some of the offerings so that I can control two motors in an Alt-Az configuration for slewing and tracking purposes?

Thanks,

Nathan

Jean-Luc replied to the topic 'Driving the mount' in the forum. 13 hours 42 minutes ago

I think I will continue on this topic instead of opening another one.
It had happened before when the mount was connected via USB, and it still happens since it is connected via WiFi.
When using the mobile synscan app and I try to bring an object to the centre of the reticle, the mount suddenly starts slewing very fast until I can stop it.
This happens whatever the slew speed is used.
As a result, it often takes me up to 10~20 minutes to achieve a 3-stars alignment.
Any suggestion for that ?
Rgrds,

That's some good news :)
I stumbled over this issue using my RPi5 running Ubuntu 23.10, it seems that there is something in QT that's not really compatible with Wayland yet as a window manager, so starting up kstars that way will use XWayland which is a kind of "bridge" between X and Wayland, I hope that explains a little anyway.

Thank you for the test, I'm sure it will help others too.

Thomas Rinaldi created a new topic ' Kstars 3.6.9' in the forum. 14 hours 2 minutes ago

I just downloaded version 3.6.9 of Kstars and tried to run it. It crashed on my Macbook Pro with Ventura 13.6.4. I would appreciate any help you can give me to rectify this problem.

Read More...

It seems to have done the trick. Can you please explain why that would help? What's the big difference between launching from shell with that variable set vs double click on the application icon?

Read More...

it's worth a shot. I'm running it now. Will post results in about 5 minutes. :)

Hi Nelson,

Can you try to start KStars from terminal like this: XDG_SESSION_TYPE=x11 kstars
I'm a bit curious if starting kstars this way will work..

I have a Raspberry Pi 4 with 8Gb RAM, which should be plenty for kstars/ekos, but I find the aberration inspector crashing ekos everytime. It does the AF run, then it just dies. No warning, nothing in the logs.

How can I produce a debug log to submit a bug report?

Setup:
- Raspberry Pi 4 64bits, 8Gb RAM
- Sandisk Extreme 64Gb card
- Raspberry Pi OS (Bookworm)
- Kstars 3.6.9 built from source using script from gitea.nouspiro.space/nou/astro-soft-build.git
- Indi 2.0.6
- Drivers: iOptron iEQ45 (Zeq45); Altair CCD; Pegasus Focus Cube; Pegasus Pocker Power Advance; Starlight Xpress

Steps to reproduce:
- Open kstars, start indi;
- go straight to focus tab, enable mosaic mask (leave default settings), run aberration inspector.

I have an Edge HD, known for it's substantial backlash, and a pegasus focus cube with 11510 steps per revolution. All maths done right and my focuser moves a whopping 23 steps per micron! I measured the backlash at between 1500 and 1750 steps, which sounds absolutely ridiculous, but when you add the 23 steps/micron scale it amounts to a very reasonable 65 to 75 microns, which isn't a lot, actually. But in Indi and especially in Kstars' autofocus settings I see that the most I can set backlash to is 1000. Am I missing something? How can I set the backlash to 1750 and keep it that way? Even if I set it in the driver settings as soon as I go to the auto focus settings it will go back to 1000.
