today we have clear and quite steady sky in Germany. So I had the chance to sketch Mars for the first time in this season.
The meridian is nearly 90° which is a quite uninteresting area. You can find hints of M. Tyrrhenum and of course the norther polar cap.
I used my 6" Mak@144x. The polar cap could be seen more easily with a blue filter. An orange filter helped not much for showing the surface details more distinct. My wife enjoyed the polar cap too, but saw no detail else.
