Afternoon, gang.
Just thought I'd let the star-gazers among you know - if you don't already! - that there is now an on-line version of Stellarium.
You can find it here:-
Do be warned; it's quite CPU-intensive. My own Pentium G5400 (dual-core w/HT, so effectively quad-core), averages high 70/low 80 % usage on all four cores. Whether it's making use of my GPU in the way the app itself does, I wouldn't like to say. But it's definitely an option for anyone who's interested in this sort of thing.....
Enjoy.
Mike.
