J-Luc, I'm shocked, I absolutely agree this is the very best image of Mars from Earth Pic Du Midi is not far from me, I need to visit one day...
Luckly your observation has been done before the new dust storm
Calar Alto in south of spain has a 1 meter telescope available for "amatour" astronomers, did you never thought to try it?
From that location Jupiter and Saturn will be a little bit higher in the sky next year
Thanks for sharing!
Thanx. No I don(t know this telescope at all.
