About this image

Mars was approaching the meridian so I captured some more video before the encroaching clouds reached it. Seeing wasn't good - Ant. III, which deteriorated as the cloud neared my target.

I then noticed that my corrector plate was starting to collect a slight film of dew. This will have softened some of the surface features.
