Thanks for let us know when DR2 is now available. I did downloaded Gaia Sky package and Gaia DR2 archives.

I executed Gaia Sky with default package. Very interesting! It immediately resulted image of Milky Way cloud from particles database!

I am now learning how Gaia Sky handle very large particle database with octree files. They are written in Java language.
