Thanks everybody for the input. A windows solution is not an option--if I really wanted to run windows I'd just use the sitech software.
I updated Xquartz on the Mac and did an ssh forward--and now I see that xephem itself is crashing on the XU4. That problem was pretty easy to fix--I hadn't added the XEphem.ShareDir to my .xephem/XEphem file so xephem was looking in /home/odroid for files and not finding them.
VNC connections are much faster though--viewing the help file over X forwarding with firefox is downright glacial but VNC is almost as fast as being on the system itself. So far VNC seems pretty stable with xephem now--it crashed the VNC client once in about an hour poking around on xephem.
Thanks again--now that xephem over VNC is better I'll go on to integrating xmtel and see how that works with my sitech controller.

I'd recommend using X11 forwarding so that you only forward the xephem application window instead of the whole desktop.

Hi Jeff,
Another setup you can try is on Windows 10, you can install the Microsoft Subsystem for Linux and XMing.
In stall XEphem in an Ubuntu instance in Windows 10.
export DISPLAY=:0.0 with XMing running and you will have XEphem running on Windows.
You can write a script and assign it an icon and run it from the Windows 10 Desktop.
contents of vbscript
------------------------------------------------------------------------
Set oShell = CreateObject ("Wscript.Shell")
Dim strArgs
strArgs = "bash -c /home/<profilename>/launch_xephem.sh"
oShell.Run strArgs, 0, false
----------------------------------------------------------------------------
contents of launch_xephem.sh
----------------------------------------
export DISPLAY=:0.0
xephem
-----------------------------------------
The question will be if XEphem will be able to address the drivers through the setup?

Hi, Jeff.
If you enable remote access on the Windows system, you should be able to use Microsoft Remote Desktop on both your Mac and mobile devices to logon to the Windows desktop and control things.
Cheers,

Hi all,
Brand new to both xephem and to the group.
I am particularly interested in xephem because xmtel works with xephem
and xmtel has telescope drivers for Sidereal Technology. I recently
converted my JMI NGT-18 to the sitech controller and servo motors but
sitech's software to date is windows only.
I have an Odroid XU4 running Ubuntu 18.04 that I want to use for xephem
/ xmtel and to drive the sitech controller. I want it to run headless
so I'd been planning on a VNC setup using x11vnc and connecting to the
XU4 either from my Mac or from an old 1st generation iPad.
I use x11vnc on the XU4 now and connection to it with tigervnc from the
Mac it is rock solid for every application except xephem. Connecting to
xephem causes the tigervnc client on the Mac to crash within a couple of
minutes of use. Every time. x11vnc on the XU4 remains running and I
can make a new connection almost immediately that will last another
couple of minutes. I've also tried the RealVNC client for the Mac and
hauled out a windows computer to test but unfortunately got the same crash.
Is this a known problem and if so is there a solution?
Alternatively I can do X forwarding from the XU4 but that limits me to
the Mac and Quartz.
Thanks!
