Re: z-dist.celx

First of all thanks for the quick response! All these distance(z) formulae are approximations only, with accuracy depending on the application under consideration. The equation you used in the "z-dist.celx" script is not an approximation, but it is an exact result for a matter dominated un...

Re: z-dist.celx

Hi, Sorry for the thread "necromancy", but I was playing with the script and I soon realized that there seem to be a couple of problems with the estimation of the redshift. First, inverting the formula z0 = (H0 * distance)/c z = z0*(1 - z0/4)/(1 - z0/2)^2 and solving for the distance one g...

How to get a list of stars around some target?

Hi all, I have the following question: Is it possible to use Celestia and via a script or addon, to get a list of stars inside a radius of x lightyears around the currently selected object and highlight them, say with a colored reticule or something? An example would be the following: Select a star,...
