MARS 14TH NOV 2009



This sketch was done at 05:10UT using SCT 8" f/10
420x, orange filter, Transparency 3/5
Seeing 3/10.

Below right are the intensity estimates.

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.
