The "allsky-website" package allows you to display your images on a website, either on your Pi or on another machine. It can optionally add an overlay of constellations and other objects, as well as optional Aurora data.
This version of the Website requires Allsky software version v2023.05.01 or newer.
The installation script for installing on a Pi is documented on the main Allsky GitHub page.
Once installed, there are several configuration variables you'll need to change. Click on the "Documentation" link in the WebUI, then the link for Settings -> Allsky Website.
