I am having some difficulty getting this to run, but it may just be me. My target machine is an RPI 4 running 64 bit Ubuntu LTS 20.04, but I am first trying to get the program to work on a separate rpi 4, running Raspian Linux 10, the processors are ARMv7.

I am able to get dotnet to load successfully ( I ran the script command for the latest version and it installed Version 6 ) and I downloaded all the files for the CollimationCircles program.

When I first tried to do the build the error I recieved told me that your *.csproj " file was asking for version 7 of dotnet, I had to change that line in the file to read version 6. After making that change I entered the "dotnet run" command. Right now it is hung on that build. I will wait and see if it finally builds, this RPI only has 1 G RAM.

Can you fill me in on what the specifics of the process will be for the machine I am running Kstars on, which I said above is an RPI 4, 8 G RAM running 64 bit Ubuntu.

thanks,

Thank you for your replay Ronald.
Did you try to play with settings? Everything is customizable, the thickness, rotation, color, radius, etc. Try to change some of the settings to get setup that is right for your scenario.

Did you try to build it with .NET 7?

Yes I did try to build it with .Net, but it gave me errors and I just assumed that it would not work on a 64 bit machine and system. I have not had a chance to try it again on an Rpi that had more ram.

I would be grateful for any specific suggestions that I should try with my system.
thanks,
Ron

If you run it withcommand it should run on every system, include 64 bit. In fact I run it on 64bit Raspbery Pi OS Bullseye.
What kind of error do you get?
You can also try to run like this to get debug output.

Cool. Is there a video or doc for how to use this app for collimation (especially RC collimation)?
Thanks,
Hy

Unfortunatelly there is no video on how to use it yet. There are some written instructions accessible via About tab.
Or you can see them here on my blog:
