43cm spec (f /7.8), 260,480×
(Note) : Seeing conditions made for difficult observation and reduced detail seen over the past couple of weeks. Over all, dark features were washed out and more difficult to see. Very little atmosphere action; no apparent north polar hood or other clouds, even with 47W (blue) filter. Hellas did appear a bit brighter in white and red (25W) light and no detail was seen inside Hellas.
