Mars Observation: Great perihelic opposition 2018
The season for visual observation of Mars comes slowly to its end. The disk diameter is now less than 10 arc-seconds, so to see the South Polar Cap (SPC) or dark albedo features one needs a telescope with lens diameter of 20 cm or larger and a large magnification of order x350 - x400. The SPC is now tiny because there is the summer in the southern hemisphere and the cap sublimates very rapidly.
