Hello,
Cyrillus, Theophilus, Catharina: mosaic. The atmosphere was rather calm. Note the smooth basaltic area due to 1000-frame stacking and moderate noise from the camera.
Copernicus: the image results from a dual-layer processing from the same stacked image to unveil topography (despite the enlightment was almost at right angles) and the ray system with high contrast.
Noticeable turbulence, I could not increase the magnification. Image resized down to 80%.
Nicolas
