When I bought the XEphem ephemeris and planetarium program in the 1990s it was the first astronomy software I used on Linux.

Now available as open source, it is still as advanced as back in the day with features few similar programs have. With its Motif user interface frozen in time and now turned retro, here is XEphem on my Linux Mint box where it still builds and runs fine. Almost permacomputing.

@amoroso Yeah same here, nostalgic memories of using this when I switched to GNU/Linux way back then. Nowadays I mostly use a combination of these two great libre and opensource astronomy apps:
⭐ KStars kstars.kde.org/
⭐ Stellarium stellarium.org/

KStarsKStars - Desktop PlanetariumThe most feature-rich free astronomy software

@JRepin I use Stellarium too (and Celestia) but I've always been meaning to try KStars.

@amoroso @JRepin I also used XEphem a lot! To the point that I joined the user mailing list. My current favourite is Stellarium but let's not forget Cartes du Ciel ap-i.net/skychart/en/start

www.ap-i.neten:start [Skychart]

@rvr Cartes du Ciel is another classic.

@JRepin

@amoroso and the funny part is, if a modern tool tried to provide those features, they'd often try to figure out a way to paywall like half the features under different premium tiers. FOSS is the only way to go with how bad normal software has become now

@JamesTDG XEphem luckly went the opposite way.
