After discovering Celestia, i find a software (free) who can see the sky all hours: (sorry for bad english...)








Screenshots from Stellarium

Download Stellarium here:
http://stellarium.free.fr/download.html

I had a look at Stellarium 0.62/Stellarium 0.70CVS , after compiling the
sources without the slightest problems under Linux. I must say
that it has many 3d graphical features, I was always dreaming
about...

No idea about its astronomical accuracy yet. But I am going to
find out...

What I find a pity is that the guy who put this in here as an
advertisement, did not dare to sign with his name....

Fridger,

Looks like a very nice program to me...

Even works very nicely on my under-powered machine too. What's really
nice about the program though, is that you can set your location on Planet
Earth, and then you can view a very nice representation of the stars and
planets as visible from your particular corner of the world.

This is very nice and thanks to the guest for pointing out the url.

Just so you know, I downloaded the Windows executable, and had no
trouble installing the thing. Got no pop-ups on the web site, no
spyware and no cookies.

Many thanks for the url there guest.

Take care, Bob

it's not bad and i have it on my box
it is very good for getting a quick look at what's what in the sky tonight

The constellation art looks fantastic! Also the realistic ground with trees is a nice touch. Comets (i.e., Machholz) aren't implemented yet, but there're already several feature requests for it so it's probably coming soon.

Hi Bob, I have no screenshots in it yet, but in my 'liens/links' page under construction in my catalog, I had quoted a lot of nice astonomic, astronautic or planetary simulators...

Had a look there Jeam... Merci!

By the way, your url should be as follows. The one you quoted above got
screwed up somehow.

Should be:

Thanks again, Bob

Waouh, very nice program .

Very pleasant to see (Milky way, Nebulas, Constellations art...) and to use (Nigth, Day, Zoom In, Zoom Out...)
Perharps some ideas to borrow for Celestia.

And more, it's seems not to difficult to replace the landscape texture with one from our "corner" (as said Bob ) to be more realistic

Thanks for the link

===================
I thought some of you might be interested to learn how you
may use Celestia's great hires planetary textures for
Stellarium.
===================

It's very easy and I successfully tested things up to a 4k size
for the Mars texture. The Celestia textures look amazing
compared to the default mini textures ( 128x128 bytes, for
example!). One may nevertheless zoom very fast from the
sky view (in the field) right into a big size mars with all the
craters etc. The rendering is still fairly primitive (~ render
path: Basic), but still...looking very pleasing.

Here are the steps:

All you got to do is to modify the h:w = 2:1 aspect ratio of
Celestia textures with any image program to 1:1 and save it
as mars.png. Same procedure for all other textures.

So e.g. take a 8k Mars texture and shrink its x-extension by
a factor of two, while keeping the y-size as it was. The result
must be SQUARE. The central meridian convention is like in
Celestia. The location of the Great Red spot on Jupiter is
incorrect in the default Stellarium texture. So you may replace
it by Celestia's default 1k one or even better by my 'great' 2k
Jupiter...

Of course, you must be a bit careful when replacing the
original textures in order not to override the originals. In
Linux on just uses symbolic links.

To test your new Mars, say, configure Stellarium such that
the red ecliptic line is displayed. Push L (fast forward time)
until you find Mars close to the red line. Mark it with the first
mouse key, and center it with the second. Then push pageUp
and zoom into your new HIRES Mars with incredible speed!

That's it.

Bye Fridger

PS

I am actually using the latest CVS version (0.70) of
Stellarium. It's compilation under Linux is really trivial for
people who have managed to compile Celestia. The CVS
version is also completely stable!

Thanks Fridger for these tips.

I replaced some moons and planets textures in your way and they are well displayed.

I am impressed with the atmospheric effects. Gas and aerosol scattering phenomena are included and still it renders very fast in my antique video hardware.
There are several acknowledgements to Celestia and its development team in this program's code. Some classes are strongly based in Celestia ones.
