• xeseds2.1.pl is a Perl script that can be used with the fifo interface. Once running, then when you click on "Telescope GoTo" over many types of objects in Sky View, a command is sent to put up a new browser window (konquerer by default) to fetch a page of information about the object from various web sites. It's quite nice. Thanks go to Tim Walker, twalker@bigpond.net.au.

• Looking for Motif? Here are prebuilt libraries and include files suitable for compiling XEphem from source on several systems. Right-click and Save the desired file, explode, and set the MOTIFI and MOTIFL macros in Makefile.smple in the XEphem source directory to point to the explode directory.

• Looking for a lightweight browser to use for the XEphem help? Try Dillo. Thanks to acrux for the suggestion.

• Looking for another lightweight browser to use for the XEphem help? Try midori. Just set up the command as midori '%s'.

• An XEphem package for Solaris is now on blastwave. First get and install the pkg-get package then run "pkg-get -i xephem". Courtesy Bruce Riddle.

• Brandon Craig Rhodes has built an excellent astronomical Python library called PyEphem based on XEphem's libraries. Even if you don't use Python check it out, it's enough to make you switch.

• XEphem runs very well under Windows using virtualization technologies such as VirtualBox. You will need to load a linux distribution such as Ubuntu.

• XEphem runs fairly well under Windows using Cygwin, including all the data bases from the commercial edition, but the process to get it up and running can be daunting and seems ever-changing. Click here or here for some experiences you might find helpful to guiding your efforts (thanks to Jean-Pierre RIVET, Jean-Pierre dot Rivet at obs-nice dot fr, and Pertti Paakkonen, pertti dot paakkonen at uef dot fi, respectively) and here for instructions on adding an icon on your Windows desktop to start XEphem. (thanks to David Brooks). There are also discussions from time to time on the XEphem forum; see, for example, this thread.

• http://www.tc.umn.edu/~brams006/xephem_ubuntu.html is a link with some tips for building XEphem on Ubuntu linux.

• http://apt.astromedia.ph/pool/non-free/x/xephem/xephem_3.7.5-1_i386.deb is a link to XEphem 3.7.5 in .deb format. Debian/Ubuntu/Mint users can install it by adding the following repository to the sources list:

• Here are the orbital elements for the new "10th planet" formatted for XEphem. Data was taken from MPEC 2005-O41 : 2003 UB313:

• Here are two more Constellation Figures files inspired by popular sky atlases used in Germany and England: eurofigs_de.csf and eurofigs_uk.csf Put them in your shared or private XEphem directory and it will automatically become available as a choice in the Sky View -> Options -> Constellation menu. Contributed by Georg Graf, georg.graf at gmx.de.

• Craig Kulesa kindly maintains a collection of RPM files for XEphem at http://loke.as.arizona.edu/~ckulesa/xephem. Thanks for your support, Craig.

• Bob Abraham has contributed an alterate image of Mars. It is made from observations from Earth and so more closely matches what a visual observer sees at the telescope than the Mars Orbiter map included with XEphem. The image is not perfectly registered with the Martian coordinate system of database objects but it is close enough for many purposes. Please see his forum posting for full details and to download the final image. To use the image in XEphem, first save your current Mars map in ShareDir/auxil/marsmap.jpg somewhere then copy in Bob's image. Thanks Bob, this is a great idea, and very timely!
