Hello Bob,
what a greatful, just-in-time hack! Thank you very much!
Now i'm waiting for clear sky's for my next Mars Observings...
My suggestion: Put this tip and the image on the XEphem Contrib-Page

I made the following hacks to this file to get it to work with
XEphem:
1. Increase image size to 2880x1440 (not sure if this is
necessary, but since that's the size of the original
marsmap.jpg file, I figured I'd better do it)
2. Rotate by 180 degrees
3. Convert to grayscale
4. Invert the color map
I then saved the file as marsmap.jpg, and then substituted the
original marsmap.jpg with the hacked marsmap.jpg file (after
saving the original, of course). Using the new map I find that a
comparison between what I see through the eyepiece and what
XEphem tells me I'm seeing through the eyepiece becomes rather
good.
Hope this is useful to other people...

PS. In case anyone wants to try this, here is a link to the
hacked version of the image (300K) to save you the bother of
making one yourself.
PPS. I seem to recall that XEphem used to come with a different
map... perhaps that would have worked better for this specific
purpose? It might be nice to have a choice of maps included...
may I suggest this be considered as a feature request?
