The common star catalogues do not contain any brown dwarfs (failed stars) or free-floating planets, so I have created a corresponding catalogue myself. It currently contains 869 objects, 15 of which are within 20 light-years.

Since I searched in vain for a long time for a reasonable database that contains data of craters and other surface features of our Moon, I created it myself. The basis was two text files in CSV format, which I was able to convert and expand.

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.
