Imaged Mars this morning in fair seeing.
Unfortunately I had the gain a little too high for each channel of the rgb data and the pole,in particular is saturated. That said still some nice detail across the disc.
There is some high cloud over the P limb. In the Northern Hemisphere the Propontis Complex is showing through and there is a prominent white cloud over Chaos,the Hyblaeus Extension is seen to the immediate F side of Chaos. Nodus Alcyonius and Utopia are well seen.
In the Southern Hemisphere Tritonis Sinus is well resolved along with Mare Tyrrhenum with Syritis Major just coming over the F limb.
Also I note an area of high cloud or haze over the Libya region.
Most of the above features also appear in the IR data. Of interest particularly in IR is how far the North Polar Ice Cap has retreated revealing,what I believe is a ring of sand dunes surrounding the pole that become prominent as the ice cap recedes. I assume the very light region to the immediate South of this ring would be CO2 frost.
