Seeing was good at the start of the session but it suddenly deteriorated. I was only able to capture a set of image.
Olympus Mons is prominent as it sticks above the clouds! The 3 volcanoes on Tharsis can also be seen. These are Ascraeus,Pavonis and Arsai Mons.
Solis Lacus is rising and there are thin clouds above Valles Marinares. Chryse can also be seen on the eastern edge.

Seeing a little better for these two RGB images taken about 1hr apart.
Small discrete cloud over Syrtis Major in addition to the usual sunset limb action.

Here is the report of Mars 28th performed with the 100mm F12 achromat.
Images were good at the beginning and seeing fading at the issue being poor.
But not good enough for the 254mm cassegrain.
Chaos is seen clear not white,boundaries enough well defined to show
features around (I attributed to be Elysium,which is wrong,to be Chaos
for the 26-27th reports).
Cap with its nevea well seen separated by a dark line.
Nix Olympica was covered by clouds,the feature itselve was captured
resolved at the limb in red light (W23A). A dark boundary was captured in
yellow-green (W11).
Syrtis Major at the limb was occulted in all color of observation. The
cloud extension was noted in yellow-green,deep blue and red channels.
Widely extended in all colors. This could means 2 alternatives: a mist
cloud,separate clouds,one dusty and the second as blue cloud well known
as on Syrtis major. Different cloud nature staying at different altitudes.
No possibility to see if the mist stays only at limb and blue cloud is
rotationg with the globe.
The seeing was so poor,in the 100mm,to see was will happen after 22H15UT.
In yellow-red colors,S.M. should appear,even near the limb in yellow-red.
A good study to undertake.
Eridania was also appearing very clear and bright in all colors.
Cap with its nevea area was appearing very clear to whitish in blue and
yellow-green colors,should be hazzy.

Seeing was again very good. Elysium is nicely seen rotating off the disk.
