At home on an Athlon 2500+, ATI Radeon 9600SE 256MB all is OK.

Did you look at the latest Cassini's image of Saturn? http://saturn.jpl.nasa.gov/multimedia/images/saturn/images/PIA05389.jpg If you try to get an image like that with Celestia you can easily see that the shadows of rings over the Saturn's body is quite lighter in Celestia than in the Cassini's pict...

Look at the following picture. It's a comparison between real image of Jupiter taken by the Globas Mars Surveyor, and a Celestia image from the same perspective. Take into account that the MGS image was corrected to enhance the moons light. Then it is evident that Celestia's Jupiter looks very reali...

Ok, GL are there, but their version is 1.2.3. Is it a too old version for Celestia?

The configure script just die with this messages: checking for GL/gl.h... yes checking for glNewList in -lGL... no checking for glNewList in -lMesaGL... no configure: error: GL library was not found I'm not the sysadm on that system, so I need to know what ask him. I can't believe that on an SGI mac...

Here I am for italian translation.
I hope I can work with that file under Window ... at the first try I got PowerPoint trying to do something with it....

I guess taht this is not really a bug, but a simple pitfall. If you set revese time a go back you'll arrive to year 1 a.C. and then you'll reach the year 0 8O , but year zero has never been counted :roll: . And in this way all the date before Christ are in error of exactly one year :? . I think is n...

With the last Detonator I've back my natural planets.
OK, on my Athlon XP 1500+, Creative GeForce2 MX all seems to work fine.

I've just installed Celestia 1.3.0pre2.
All seems right, but planets (not the moons) have a light inside,
they have their own texture map, but they have'nt a dark side.
What's appened?

OK, I filled up my univers with galaxies. That's great! ... but now they appear clearly in any direction no matter how they are far or faint.
Did'nt you take into account these parameters when a galaxy is drown?

IMHO

1. A 15" monitor 800x400 can be upgraded :? at least to a 15"@1024x768
CRT or, better, :idea: LCD.

2. A GeForce 2 32MB card is a little undersized :roll: for a 19"LCD (I hope you catch a 1600x1200 one 8O )

A long time ago, I posted my more realistic moon. Chris told that he wanted to include it in the new releases, but He probabily forgot it. Here's the moon I obtained http://www.cineca.it/~avl0/A%20more%20realistic%20Moon.jpg And here the albedo map I used with the standard bumpmap twice higher than ...

Since last october 28th a season of reciprocal eclipses and occultations of the Jupite's moon has began. I tried to see these phenomena with Celestia, but I can not replicate any of the coming eclipses. E.g. try January 27th 2003, 19:50UT, Europa should cause an anular solar eclipse on Ganymede, but...

Where did the number 10 billion come from ? Last I heard, estimates of the number of stars in the milky way ranged between 100 and 200 billion. I wouldn't expect Celestia to handle this - I'm Mad Boris, not Stupid Boris ! What is Moores' Law ? To compute the gravity force between two bodies we need...

Yes, it works, just look at Io disappearing in the Jupiter's shadow.
What is not yet working are rings' shadows on planets and moons,
isn't it?

I'm happy to answer a Chris' request.
I'vo got two minutes and I've installed Celestia 1.2.4pre1 on our SGI VisualWorkstation 540 running Win2K with the latest drivers.
As you can see, eclipses still show the cross like shadow bug.

My personal guess is that this is a big hoax. Small bodies have very cahotic orbits, on a so long time scale it can run for more than undreds BILLION of Km, to be sure that one of such body can hit the earth you should have a precision much better than 1/10Million. Which is unbelivable. I'd like to ...

Well, eclipses behaves in the right way and the planets project their shadows on their satellites. But if you are far enought from the satellite you can still see it even if it is completely in the dark. Then if you get closer and closer the satellite will disappear as soon as its diameter become vi...
