Stellarium
The biggest improvement for my stellarium usage was creating my own landscape¹, as having a quick way to see whether that early morning partial eclipse is behind <i>those</i> trees is really useful.  Also, kinda super fun to sit in your office chair spinning around your own garden.<p>I actually created a bunch of landscapes for places that I have reasonable access to, so that I can choose an appropriate place for observations without having to resort to guesswork.<p>I'll note that you can create usable versions with the panorama function on a cheap phone and gimp.<p>¹ <a href="http://stellarium.sourceforge.net/wiki/index.php/Customising_Landscapes" rel="nofollow">http://stellarium.sourceforge.net/wiki/index.php/Customising...</a>
