I had nice conditions this morning for Mars. The extra diameter is bearing fruit in terms of the resolution of fine detail.
The image is derived from 4 RGB runs.
To the north, the large red plain of Amazonis Planitia extends right across the planet from this aspect. Good detail is visible here.
The cones and surrounding elevated terrain of Olympus Mons and further south, Arsia Mons, have created shadows extending towards the terminator, as the Sun sets on them.
The large albedo area of Terra Sirenum to the south exhibits some dust cloud activity, especially towards the rapidly shrinking South Polar Cap and more to the f side of the CM.
