It's a close-up image of central Imbrium, MARE (Sea of Rain). In case of low powered magnification, you can appreciate only flat and dark appearances in mares of Moon, but you can enjoy unexpectedly interesting lunar topography in them near the terminator because subtle and uneven features make clear shadows.
In this Imbrium, MARE, several small craters with their diameters smaller than 30km and some peaks are making shadows.
