Digging in the Celestia data base and producing nice tables of output --given some search criteria--,
could be very interesting/useful future applications for the powerful Lua-scripting that is presently under development.
Double star names would be almost trivial, but one may also search and display much less trivial entries that may be of great interest to amateur astronomers and the like...

Yes . . . I want to make it possible to write a script that iterates over the entire star database. Something like this would mark all intrinsically very bright stars in the sky:
Code: Select all
for s in celestia:stars do
if s.absoluteMagnitude < -6 then
celestia:mark(s)
end
end
Double stars would be a bit trickier, as Celestia currently doesn't store any correlation information--double stars are nothing more than stars that happen to be positioned near each other. But, that could be fixed, and in fact, it will have to be fixed when we want to make stars orbit each other.
