I'll need some help with the globular clusters
Posted: 31.08.2020, 14:42
Hello
Yesterday I was flying inside a couple of globular clusters, like 47 Tucanae, and I was thinking about making my own fictional clusters. I have a fictional system from the ArcBuilders Universe and I tried today to make a fictional globular cluster to fill the empty space around it with some stars. I used the 47 Tucanae as a base, changed some numbers, and made a .dsc file at the extras folder with this:
The problem is that Celestia doesn't load it, doesn't even recognize it. I hit ENTER, try to type the name of the cluster, and there isn't in the list at all. What I did wrong? I don't get it.
By the way, I have some questions about globular clusters. How big can they get? What exactly is the CoreRadius? What will happen if it has the same value with the Radius? KingConcentration is about spreading the cluster, making the core more or less dense? What's its maximum value? What exactly are Axis and Angle? Can I make a cluster big enough and spread its stars with such a uniformity, to fill some caps in Space?

Code: Select all
Globular "Magni Cluster"
{
RA 79.683917

Distance 11800
Radius 100
CoreRadius 0.4
KingConcentration 2.03
AbsMag -5.00
Axis [ -0.7429 -0.2364 -0.6263 ]
Angle 175.9
