Wow, this looks really great!  We were just talking about strategies for 
expanding the number of stars recently.  I would love to be able to use the 
Stellarium catalogs directly.  I'll have to take a look at the catalog files.

Unlike stellarium, I believe our strategy will be to avoid reading the entire 
catalog into memory at the same time.  We will likely only make fainter stars 
available at higher zoom levels, so that we can split the catalogs by 
position on the sky, and selectively load the sections that are on-screen.

We need to continue figuring out exactly how this is going to work, and then 
start implementing it shortly after the 4.0 release.

Thanks for the heads-up!

regards,
Jason
