I created a lite version of the current HYG star catalogue with 120,000 entries. It contains fewer columns, reduced accuracies and is half the size of the original. The result can be downloaded as a SQL import and in the form of Povray arrays.
Finally I have a decent Povray package ready for release. It contains a macro that uses high-resolution images to create an almost photorealistic image of the Milky Way. Only a few lines of code, but it really makes a difference.
