Details:
Yesterdays Moon, lit around the phase of 66% here elaborated in two different versions. The first one is the classic in grayscale, to enhance all the surface details that I managed to capture with my DLSR camera, then another one in over color saturation, to show the different composition of the lunar soil.

The areas that emerge in a strong blue color (mostly in the Maria regions) are areas rich in Titanium, proof of ancient lava flows, and those contain more titanium in contrast to the Maria orange regions, that are poorer of this material.

The classic example is the difference between the Mare Tranquillitatis and the nearby Mare Serenitatis, with a striking contrast between the two regions. The areas in light orange instead show the lunar higlands, and iron poor areas, but rich in aluminium feldspar.
In this second elaboration the ejecta features emerge in the same manner, because they are (in some evident cases) over the older geological features.

Instruments: Canon EOS 700D with Samyang 500mm f6.3 Lens - stack of 25 images (on 100) with AutoStakkert2, elaborated with Registax and Photoshop CC.
