Some photos of Plato crater and Vallis Alpes. GSO 305 mm - ASI120MC . Some photos with barlow 2x ED GSO.
I found some curious facts:
1) Mare Imbrium has more depth than Plato and Vallis. And all them have theirs basin full of lava material. And is thought that the lava layer of Imbrium has 5 km depth. Perhaps some features are missing inside, only the top of high mountains can be seen
2) Vallis seems to be flooded from Imbriun, but how the lava went there if it is higher ?
3) Plato is slightly younger than Imbrium, but the meteor found a similar situation of Moon that caused flood of lava in its interior.
This one is too large:
