It is always refreshing to look at the martian surface features very early in the morning. This morning the early sky was clear but seeing was poor. Dew became a problem on the front end of the corrector image making it harder to look at the surface details at high power. When I switched on the dew remover band twilight was within reach.
Arcadia region was prominent, probably due to the contrast with the white pole cap. Also evident was a hazy Solis Lacus and part of Lunae Lacus.
