Pictures by telescope. Aristarchus crater on the Moon in Registax 5.

Aristarchus (40 km) is one of the most distinct craters on the lunar surface though it is small in size. That's because its brightness when in contact with sunlight. It makes a great pair with Herodotus (35 km), which is about the same size Aristarchus, but very different from it, since Herodotus is flooded.
We can easily see debris thrown around Oceanus Procellarum from Aristarchus, ending up at Kepler (32 km), another crater to the southeast of it.

Herodotus appears as a bright ring near Aristarchus and between the two we distinguish a curved westward channel called Vallis Schröteri. In the area of this channel, the terrain color is darker.

Towards the west of two, it is an isolated crater called Schiaparelli (24 km), and further, the terminator is a large crater which it is lit on the outer edge, called Seleucus (43 km).

In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.

Visual astronomy. Craters-Eddington and Seleucus.

To the east of the immense flooded crater Eddington (125 km), is a small crater named Seleucus (43 km). It is isolated on Oceanus Procellarum, and at this lunar phase is bright. A bright streak of light move to its east. This seems to arise from the north of Montes Agricola, passes Seleucus and stops bifurcated east of crater Cardanus (50 km).

At Eddington is observed its flooded rim in the south-east. Dark spots in the picture are actual hardened lava that flooded all the craters in this area, and the white spots are the edges of these craters.

On the top-left in image are seen some a bit of crater Krafft (51 km), in whose center is a mountain peak.
