Hi there,
Lead Dev for OpenSpace here. We do have the ability to render galaxy (or any point cloud dataset really) in 3D space as well as stereoscopically. For an example see a video we made for Matt from SpaceTime a while back: https://youtu.be/E8rel2-kLJA?si=yqQZr7Nk9dyMDqZa&t=373 Thst video uses the Tully, and Sloan Digital Sky Surveys and then a catalogue of Quasars.
It would be fairly straightforward to add your random galaxy dataset as an asset as it would only require some light Lua coding and a CSV file with positions + any additional variables
