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 those trees is really useful.  Also, kinda super fun to sit in your office chair spinning around your own garden.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.I'll note that you can create usable versions with the panorama function on a cheap phone and gimp.¹ http://stellarium.sourceforge.net/wiki/index.php/Customising...
