Astronomy / Stargazing AR App Tutorials

I’m interested in creating an AR app similar to SkyView or SkySafari that lets you identify planets, constellations, and satellites. Another feature I would like to include is a constellation illustration overlay. Does anyone know of a good tutorial or documentation I can follow to get started?

This is good for constellation and star mapping using cube maps for a sky sky in unity. However, names of constellations are not used. - NASA SVS | Deep Star Maps 2020
