Skybox with all the real stars/constellations ?

I am looking for a real-world skybox with all the constellations and stars... I know that Google Earth has a Sky-view with all the stars and constellations. Where can I find something like that ? Should I try to screenshot some by myself ? If I manage to make a skybox by myself I will definitely post it. But I am sure there already are some well done ones, I can't be the only one who thought about that? Any website ? Any link ? Anything on the asset store ?

Thanks Kiwi.

 

I guess i should take some by myself....
I will post them once done

Maybe this helps? haven't tried it myself but I always google nasa + what I want to see concerning space.., got the moon working in another project that way for example.

 

Omg, thank you very much this will be extremely helpful, I am glad there are other people who like astronomy.
Thank you !

 

Thank you very much! I've never taught I'll find this kind of texture, but how can I put it in unity ?
