Electronically Assisted Astronomy with a Jetson Nano

Hello,

still working to get the good setup for AGX Orin.

Back to KStars which is really interesting.

It could more suitable to build KStars for the Jetson Nano/XavierNX/AGXOrin. To do this :

sudo apt-add-repository ppa:mutlaqja/ppa
sudo apt-get -y install build-essential cmake git libstellarsolver-dev libeigen3-dev libcfitsio-dev zlib1g-dev libindi-dev extra-cmake-modules libkf5plotting-dev libqt5svg5-dev libkf5xmlgui-dev libkf5kio-dev kinit-dev libkf5newstuff-dev kdoctools-dev libkf5doctools-dev libkf5notifications-dev qtdeclarative5-dev libkf5crash-dev gettext libnova-dev libgsl-dev libraw-dev libkf5notifyconfig-dev wcslib-dev libqt5websockets5-dev xplanet xplanet-images qt5keychain-dev libsecret-1-dev breeze-icon-theme

mkdir -p ~/Projects/build/kstars
cd ~/Projects
git clone Education / KStars · GitLab
cd build/kstars
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=RelWithDebInfo ~/Projects/kstars
make -j16
sudo make install

This works for the AGX Orin. I guest it will work for the other Jetsons.

Using INDI drivers, it is possible to control the mount with KStars. This means you know exactly were the camera is looking and what you are looking at.

I made some tests and everything works fine.

Here is the complete setup (indoor tests):

On this screen capture, the mount (Skywatcher Alt-Az) is looked on the Bode’s galaxy (M81). You just have to choose the target with KStars and send a GOTO command to the mount and that’s it. If you manually move the mount, KStars will get the mount position and display it on the map.

Just need now to make some tests at night. I will also try to get the mount position in JetsonSky to put those coordinates in the video.
