Celestia still has a great potential in it. Nice work!

Re: 1 billion star ESA Gaia catalogue in Celestia?

Oh, thanks.So these are the relevant star catalogues: 1.) Hipparcos Catalogue (118,200 stars), 1997 2.) lower-precision Tycho Catalogue (more than a million stars) 1997 3.) enhanced Tycho-2 Catalogue (2.5 million stars) 2000 4.) Extended Hipparcos Compilation (XHIP) (116,096 spectral classifications...

It is HUGE! Ingenious! I wish Celestia would be able to create galactic maps like this "in real time"...

Re: 1 billion star ESA Gaia catalogue in Celestia?

I don't really get it. This is NOT the new Gaia TYC2 (very accurate) catalogue... Isn't it already available in Celestia (XHIP catalogue)?

Re: Add 1 MILLION stars in M31 (Andromeda's galaxy) !

SVision: of course we can see galaxies, what I meant was we cannot see the individual stars in M31, like we can see them in the Milky Way. We cannot measure their distance etc. one by one, because we only see their combined light, not the individual objects.

Re: Exporting a Blender model with textures to the 3ds format ?

Selden: I downloaded from http://nasa3d.arc.nasa.gov/detail/mars-rover-curiosity the 29.04 mb stl file and only 3d parts were in it...like body, chemcam, legs etc..

Added after 6 minutes 29 seconds:
By the way, Selden, your model looks spectacular in Blender!!! :clap:

Re: Exporting a Blender model with textures to the 3ds format ?

The NASA model is not assembled. If you have it already in Celestia, you have the 3ds or cmod version of it. Here you can download cmodview: http://celestiaproject.net/forum/viewtopic.php?f=25&t=17413&p=134262&hilit=cmodview#p134262 Open it in cmodview, click on certain parts of the mode...

Re: Add 1 MILLION stars in M31 (Andromeda's galaxy) !

I think using more binary star sources or 64 bit addressing would be nice... By the way, as I know the 2 million stars Tycho catalogue is not very accurate. There will be in September a Gaia release of reworked Tycho catalogue of these stars: "In addition, for a subset of data – about 2 million...

Re: Space Engine

Space Engine is a game, not at all realistic in it's graphics. If you want to play a video game, it's OK, but it is not space simulation, it's a fantasy space game.

Re: Add 1 MILLION stars in M31 (Andromeda's galaxy) !

I know I'm getting boring, but if 1 million star is slowing down Celestia, how can we use the 1 BILLION Gaia star data coming up at 14 september? :cry:
