Xephem. Great Astronomy software for Linux. Still works on Ubuntu.


Xephem is a very old UNIX program, that is still able to be installed on a modern Ubuntu 18 desktop.

Download all of the packages here into a new folder.

http://e2rd.piekielko.pl/debian/binary-amd64/.

Then we need to prepare for the installation of the packages.

Install these two packages with apt to satisfy dependencies.

libmotif-common
libxm4

Then we can install the packages. Installing the main program now.

And install the required star catalogs.

After all of this, the program is ready to run.

This is a dated Motif interface, but easy to use. Just set your location and you are ready to go. Below is the Xephem sky view.

And a nice view of the Moon, showing all Apollo landing sites and other nice tourist attractions.

Also, there is a data table showing the Declination and Azimuth of various sky objects.

This is very useful to program into a telescope to find a stellar object, also Xephem can directly control a suitable telescope, this means that the `scope would automatically track to a desired object.

Finally, there is even a sun view, but the image I got was from 2009.

This is a very nice program. Good to get a quick view of the solar system and look for a certain stellar object. I used to play around with this program ages ago and it is great that it still works very well. I tried to compile this on a Macbook, but it did not work.
