Last few days here in Poland were quite impressive for astronomy amateurs. Weather was good and stable in large area, and also Moon was moving from new moon to first quarter, so was not disturbing much. Last night atmosphere was stable with decent seeing and Moon shined pretty high in the sky, so I was tempted to make a few pictures. Visual observations revealed much detail in many Moon features, and I picked for imaging three ones.
Eudoxus (67km diameter, 3400m depth) and Aristoteles (88km diameter, 3300m depth) craters with Montes Caucasus to the left. Sun is low in the sky in this Moon area, so Montes Caucasus cast very long shadows (a few dozen kilometres). Montes Caucasus spans for over 450km, and its tallest peaks reach 6000m.
Lacus Sominorum – “Lake of Dreams”. This is largest of the lunar features designated by word Lacus (lake). Its diameter is 384km. It is irregular feature with complex borders. The surface has low albedo, as the larger lunar mare. Large crater at left is Posidonius (95km diameter, 2500 depth).
Julius Caesar crater (in the centre) is an impact crater with low and heavily worn walls. Its diameter is 90km and the crater is 3400m deep. Rima Ariadeus rille is over 300km long rille. It is relatively young lunar feature, with a few craters overlying it.
