The images were pretty good with 435x. I was at the issue of the period
more disturrbed by the moisture deposition on front glass than with seeing
(but it failed significantly also).
At the evidence the equatorial zone is well lighted and confirmed with the
banding structure well evident too. What was surprising me was the polar
cap clearer bordered by a thin lighted zone as shown.
Albedo variations are reported into bands but the gain of the W8 filter was
faded by the borning moisture deposition. I stopped after.
Nevertheless here are these 2 sketch that surprised me by the observation
quality: this means the contrast stronger than say 2 month ago now.
The period is interresting to follow.
