Hello,

Is it possible to put a picture of the Andromeda galaxy over the default gray thing? How would I go about doing that? I'd like to do it to many of the other ones too.

I'm using pre11.

Christoria,

Putting flat pictures of objects into Celestia is relatively easy. The web page http://www.lns.cornell.edu/~seb/celestia/billboard.html shows one way to do it.

That was exactly what I was looking to do. Of course, a 3D galaxy would be better, but this is excellent. Your files with the descriptions on how to use them were perfect and very simple.

This still needs to be tweaked a little, but here's less than ten minutes of work:

Wow! That's an awesome 10 minutes of work christoria! You've now given me an idea of what to do with all those high resolution galaxy images that've been sitting in my other computer for a few years. I was originally rotating them as wallpaper. I've also had some difficulty trying to re-locate the website(s) of their origin. I'm so glad I hung on to them. Gotta go, PhotoShop is calling!

Hey, that was a project I was thinking about. Well, who comes first...
95% of all good galaxie images comes from either

eso -> http://www.eso.org/ or
hubble -> http://www.stsci.edu/resources/

but you propably want to go directly to

http://www.eso.org/outreach/press-rel/ ,
http://www.eso.org/outreach/gallery/astro/ ,
http://hubble.stsci.edu/gallery/ or
http://heritage.stsci.edu/

work for MONTH...
I'm sure you'll find your pictures there. And don't forget - there always hires versions available too.

Have fun

Another source of high resolution pictures (up to 4K TIFF) is NOAO: the U.S. National Optical Astronomy Observatory. They allow their images to be freely reproduced when used for "educational outreach activities composed by amateur astronomers". I think that's what we do

Nice links, thanks for sharing!
