No nebula on Celestia

[Goonster]

Hi . I know it`s probably obvious,but how do you get to see things like the Orion Nebula? I have been able to visit most other things but I cannot get to see any nebula`s, which is a shame because they are some of the most spectactular sites in the sky. I`m a newbie with this program and am still getting to know how everything works . Thanks.

They're not ready yet... there are some nebulae add-ons available here:

Extrasolar (Deep space objects)

I also recommend Rassilon's NGC 1999 and Rosetta Nebula add-ons but I don't know where they are.?

Install this cool add-on by Chance Ragen

That looks neat... thanks Reiko. Selden... I had a look there but couldn't see NGC1999 or Rosetta on the list.

bh,

You probably overlooked them because the names aren't what you expected.

NGC1999:

http://www.celestiaproject.net/~rassilon/ngc1999_patch.zip (3KB; identical to V380_patch.zip)

Rosetta:

Of course... been a while.

Thanks for that . No point in looking if there`re not there then . I downloaded
the real color earth add on by Shadmith from Motherload but can`t figure out
how to add it on , ( only been using a computer for 6 months ). Also why is it I can find files containing textures and photos in the Celestia file , but when I open up the same files in the program they are all empty?Confused!
I use a Dell Inspiron 6400 laptop , Intel(R)CPU,T2080@1.73Ghz , 1014Mb RAM with Vista Home Basic

Goonster,

Even being an expert with computers won't necessarily make you an expert with Celestia

Put Shadmith's Earth.png into Celestia's directory
Celestia\textures\hires\

You'll then be able to see it if you type a Capital-R several times to see the higher resolution versions of the surface of the Earth. Type a lower-case-r several times to see the lower resolution versions of the surface of the Earth.

[Goonster]

Thanks for the advice . I`m still learning the ins and outs of computers . You might not have to be an expert at computing to use Celestia , but believe me it certainly helps!

Goonster... here's a good place to start... top of list.

Although there are plenty of friendly folks here who'll help you out if you get stuck.

how do you install these? there are no readme files w/ directions

[bh]

I think you can just drag their folders into Extras...? Not sure 100% though. I remember I had some trouble with V380.

The results are well worth it though...

[selden]

As I mentioned, two of them are used as examples in http://www.lepp.cornell.edu/~seb/celest ... intro.html
That Web page should help you to understand how to install otherwise undocumented Addons.

Well I've just downloaded and tried to install M4 from Rassilon's directory and I get nothing in Celestia...? Help. Using 1.4.1

I think you can just drag their folders into Extras...? Not sure 100% though. I remember I had some trouble with V380.

Take it from me... You can almost NEVER just drag an add-on into the
extras folder and expect it to work correctly. I know, I know... This
goes against everything you see and hear, but believe me, it simply
doesn't work that way. You may have STC files involved, and from
what I've seen here lately and unless you know the creator very well,
this add-on installation method simply doesn't work.

I always extract my downloads to a separate folder, and then copy
each piece of an add-on to the places where I KNOW they should go.

Then too, I have multiple directories in my extras folder... I have one
for spacecraft - with its very own data, textures\medres and models
folders, as well as multiple other folders all set up the same way.

Got one for Galaxies, one for Nebulae, one for - well, you get the
idea...

If the add-on is from Runar though, you SHOULD be okay.

bh,

Ras' didn't provide any object named M4, although that's the name of the Addon. (I think it was just an oversight, though.)

All of its member stars are rather dim (most with apparent magnitudes of about 15), so you won't see the cluster unless you turn up Celestia's limiting magnitude.

Here's a DSC catalog to define the cluster's location. It's actually a globular cluster, of course, not an OpenCluster. Celestia has no explicit globular cluster declaration.

Code: Select all

OpenCluster "M4" {
RA  16.39317
Dec -26.52553
Radius 140
Distance 6850 # changed to agree with Ras' cluster
}

Thanks for that Selden... got it... looks like christmas lights. Another prob though... all ringed planets are unviewable... and Celestia locks up.

[selden]

Only a few surface textures are included in the M4 addon. It assumes you also have installed one of Ras' other addons which includes lots of surface texture images. Sorry, I don't recall right now which one it is. I think it's related to the globular cluster generator software.
