Astro pictures through telescope: Craters Firmicus Apollonius and Mare Spumans. Lunar selenology.

These craters of the Moon are located on the west as seen from the Earth (which is always the same face toward us).

 In the photos below I put the name of each crater or sea, to be easier to locate, and craters with satellite craters named with letters, have their colors.
These astronomical pictures are from the video that can be found here: Video by astronomical telescope-near Western Mare Crisium.

    Firmicus (56 km), is a lunar crater that is located in the eastern part of the Moon, and appears oval due to its position near the edge. It is however almost circular.The crater is located west of the Mare Undarum, and northeast of the crater Apollonius (53 km), similar in size. North of Firmicus are craters van Albada (22 km) and Auzout (33 km). Annexed to the northwest edge, is Lacus Perseverantiae wich is a Moon sea in miniature.

Apollonius (53 km), is a lunar crater located west of the Mare Undarum, north-east of Sinus Successus wich lies on Mare Fecunditatis, and north of Condon crater (35 km).
Apollonius's outer rim is somewhat worn and is superimposed by a pair of small craters (including Apollonius E) on the west wall. The  interior is almost flat, the floor has a low albedo and has been covered by lava. It has no central peak or notble small craters on the floor.
Both craters, Firmicus and Apollonius have a depth of 1.5 km.

Mare Spumans (139 km), from Latin "foaming sea", is visible in these lunar images, and is located south of Mare Undarum. Apollonius W crater is located on the western edge of the sea, and south os the Mare is Maolaurin crater (50 km), and its sateklite craters T (35 km) and H (44 km).
