I've seen several YouTube videos, as well as read a few posts, about the Astral Dragon. My research into the matter appears to show the creature as being present in earlier (4e, 3.5e, Pathfinder, etc.) editions of Dungeons and Dragons, but apparently it didn't make the cut to 5e, or perhaps is going to be added later.
Does anybody know of any kind of homebrew Astral Dragon stats that have been produced and published out there on the internet, or perhaps a Wizards Unearthed Arcana blog post that might detail information on how to bring this fearsome creature into my 5e campaign?

I know of no official conversion, as of writing. However, were I to write a conversion, I would begin by comparing the stats from D&D 3.5, where the astral dragon appeared in Dragon magazine issue 344. I would then use that to adapt an existing 5e dragon (which for copyright reasons I won't replicate here).
The astral dragon is approximately as strong as a brass dragon of similar age, and we can use the 5e statistics for that as a basis, modified as follows:
Astral dragons are always of Neutral alignment. They consider themselves guardians of the Astral Plane, and consider all non-native visitors to that plane equally their enemies.
