About this image

Just over two weeks from opposition and we still aren't getting great seeing in Canberra, but at least the wintry rain has backed off, and the seeing did improve a bit last night, so it was worth swapping the colour camera (462MC) for the mono camera (290MM).  Mars here is seen with a much reduced polar cap, with clouds over the Tharsis Mountains, while Olympus - apparently unclouded from my inspection of the blue channel - glimmers at the terminator.
