Labelling of stars in Celestia

Post #1by skipperp » 21.09.2007, 04:51

Hi,

I wish to get a screenshot of all stars within a 50ly radius sphere from Sol and I've setup the view in Celestia however is there a way to have all the stars within the "sphere" labelled as well? Only a few stars are labelled, I played around with render - view options etc but no luck. Any ideas? Thanks for your help.

Cheers, Paul.

Paul,

v1.4.1 shows labels on the stars which are listed in celestia.cfg

v1.5.0pre3 shows star labels differently: on all stars which are brighter by a certain amount above the current visibility threshold.

At the moment, the only way to guarantee particular stars are labeled in both versions is to provide your own list in a DSC catalog, either as OpenCluster or Nebula objects. They'll be visible whenever either OpenCluster or Nebula labelling is selected.

Ok thanks, I played around modifying celestia.cfg and it shows Proxima for eg OK. Looks like I'm going to have to enter them all manually. Within 17ly for eg there's already 50 or so stars to enter...

Other question is if I set my position close to Sol one can set the "Filter Stars" distance option in Render -> View Options to say 50ly to see all stars within that distance however if I move away from Sol say 50ly I loose some stars as they are outside my visibility sphere, however I still wish to see all the stars within that 50ly radius sphere, any way around this? Thanks again.

Cheers, Paul.

There's a script which do just this. Do a search on the scripts forum.

skipperp,

(depending on your OS,) you can adjust the distance filter for star displays to 50 ly first. That displays all stars in a sphere of radius 50 ly. Then you switch off the automag and galaxy label displays. Then you increase the brightness (] key) to a maximum. That labels all stars within 50 light years. You may want another perspective though.
