Another delightful lava field, peppered with interesting features including the Straight Wall. Fra Mauro has passed me by, along with crater Parry next-door; Fra Mauro has very poorly defined walls on Quickmap but under this illumination was very clearly a prominent crater. Interesting rille system extending through Parry and into Fra Mauro which was nicely illuminated whilst observing. A region worthy of further observation at higher magnification.

Full resolution on the 585MC (no filters). 2000 frames captured in SharpCap and best 5% of the these stacked and sharpened in AS!4, and levels and curves etc adjusted in FastStone Image Viewer.
