I used until now only
stellarium.org and I'm curious if there is any other software that is better than stellarium. By better, I mean:
- doesn't have high system requirements
- requires very little power from the battery when running(as the normal setup would be going somewhere outside with the telescope and a laptop.. this may be hard to estimate, but maybe there is here someone who tried out more than one program and has seen a clear difference)
- easy to use
- has extra features (extra star catalogues, telescope control, etc)
A big plus would be if that software is free for personal use!
