Hardware

Raspberry PI preparation

Step 1 : install Rasbian

Step 2.a: install git, create ssh key,

Step 2.b: rasp-config; enable ssh (change user ssh), enable camera

Step 3 create Hotspot wifi

Step 3 RPI camera

Installation :https://www.youtube.com/watch?v=Z8cs1cRrc5A&list=PL8I-BdkkiusTgkBDhqACvZAtO675Z6b2j

Remove camera lense for rpi camera (only NoIR) https://forums.raspberrypi.com/viewtopic.php?t=365864

Autoguidage

• https://www.webastro.net/noctua/astrophotographie/autoguider-avec-une-monture-sans-port-autoguidage-r160/

Software

Step 1 - Install INDI, indiwebmanager, PHD2

Check scripts in https://github.com/herseyc/raspastro

./install-raspastro-dependencies.sh (caution with error dependencies)
sudo apt install libcamera-dev

# Install gpsd + set file /etc/default/gpsd
./install-gpsd.sh

// INDI installation
./install-indi.sh

// Indi libraries installation
./install-indi-driver.sh (caution to drivers to install)

# Need for Phd2
sudo apt-get install build-essential git cmake pkg-config libwxgtk3.2-dev wx-common wx3.2-i18n libindi-dev libnova-dev gettext zlib1g-dev libx11-dev libcurl4-gnutls-dev libopencv-dev libeigen3-dev libgtest-dev
./install-phd2.sh

./install-kstars.sh (OPTIONNAL)

Drivers

• indi_asi_ccd for zwo cameras
• indi_libcamera_ccd for raspberry pi camera, indi_rpicam is deprecated
• indi_gpsd for gps or virtual gps
• indi-astrometry

Step 2 - For zwo ASI 120/Datyson T7 only

You need to upgrade firmwire, use *-compatible.iccfile and do it on windows

Step 3 - Virtual GPS

Only if no GPS card

• https://github.com/rkaczorek/virtualgps
• http://www.suffolksky.com/2022/01/06/setting-up-a-gps-module-on-the-astroberry/
• https://raspberrypi-tutorials.fr/construire-un-dispositif-de-localisation-navigation-gps-raspberry-pi/

Commands for testing :

$> cgps
$> gpsmon

Step 4 - Astrometry

• https://www.webastro.net/noctua/logiciels/contr%C3%B4ler-son-t%C3%A9lescope-facilement-avec-un-raspberry-pi-4-r212/ -> chapter astrometry
• http://data.astrometry.net/4100/
• https://docs.kde.org/trunk5/fr/kstars/kstars/ekos-align.html #Obtenir optionnellement astrometry.net

Step 5 - Indiwebmanager

Run indiwebmanager and start indi + drivers http://<ip_raspberry>:8624

Step 6 Kstars/Ekos

Test all in local

Step 7: VNC

• https://github.com/novnc/noVNC#browser-requirements
