Will we ever have clusters?

[jook00]

I can only zoom out till the galaxies disappear. I really really hope there is a way to show clusters of galaxies until the whole screen is filled with our whole universe with clusters and super clusters. Is there a way?

p.s. I still can't get any add-ons to work. I put files into extras folder and put the images according or what the ReadMe says. Nothing ever shows up though, neither can i search for it because its not there.

There are clusters of galaxies within the presently incorporated NGC/IC catalog of 10000+ galaxies. Go to the region of M 91, switch on the automag (CTRL +Y), hit E to see their names, increase "Automag Limit at 45 degrees" to ~8.0 ( ']' key) and zoom in and out slowly...using SHIFT + mouse-Left movements forth and back.

i just put the automag all the way up to 12 to see more galaxies. however, zooming out just makes them disappear as I get out farther, and there is no view of the clusters like for the standard 3d galaxies.

Please Celestia, make some 3d clusters for us to view? i don't even mind if its fake, i just want to see it.

Check out this picture:



Each point of light is a galaxy. Looks like a cluster to me. It looks quite impressive within Celestia as you rotate around it.

Try starting about 30Mpc from M 91: cel://Follow/M%2091/2005-08-23T21:13:14 ... 23&lm=2060

set magnitude limit to maximum ( ] key ), and then use your WARPDRIVE to travel through the cluster at 1,250,000 ly/s (Warp=9.99999992)

The vanishing of most galaxies at large field of view (FoV) is on purpose!

Celestia takes naked eye vision as the basis of its
display at large FoV. Most galaxies are dimmer than 6-7
mag hence invisible to the naked eye. Zooming in
emulates "telescope mode" in some way. Hence many
more galaxies pop up when zooming in! I made the labels
of more distant galaxies increasingly transparent which
gives a neat 3d impresion.

I think you simply don't know yet how to properly handle Celestia's controls
How about this?


To most people it seems that we got enough galaxies in
Celestia . We actually got ALL down to some very dim
magnitude of ~16. It's the complete revised NGC/IC
catalog. Not a single one is missing!


As to /star/ clusters (not galaxy clusters), I am working to implement these since quite a
while. Most infrastructure in the code is already there.
And I also got the complete catalog data. But the rendering with
sprites still needs some further consideration AND I should need more spare
time!

What is much harder than clusters is the /mass rendering/ of
diffuse nebulae like M42 (Orion).

At Celestia, we strictly apply scientific level visualization
standards. That's why such tasks take their time.

I do love Celestia though. I have tried STARRY NIGHT and it didn't come close to the cool navigation of Celestia. I like to show off to my friends how small we are compared to the universe with this program.

I did have one concern though. I have noticed that when I zoom out, the stars get smaller as they should, but after a certain point, they don't shrink in size anymore, they just seem to fade out. This makes the stars seem closer together than they actually are.

GREAT screenshot of that cluster of galaxies! I know that galaxies become invisible to the naked eye, but when viewing many galaxies from a distance, doesn't it begin to look like a galaxy, but where every dot is a galaxy and not a star? Like when all the many galaxies get small that you can hardly see, they should be visible if they're bundled up. Maybe I am wrong :p anyhow, I am just so eagar to pan and rotate around a cluster that looks like the video I saw at the end of http://youtube.com/watch?v=nYyHTmF0vjY (sorry if i'm breaking the rules... AM I?).

Here's another exciting journey.

Start here: cel://Follow/NGC%201310/2005-08-23T21:3 ... 71&lm=2060

then set your WARP speed to 9.999999924 (5,440,000 ly/s) and travel first through the Fornax cluster, followed shortly thereafter by the Virgo cluster.

... and to make it a little more interesting, once you're underway and up to speed, try selecting and tracking ("T") the Milky Way (or Sol).

(Don't forget to increase the magnitude limit)
