Schickard saw Arcturus in broad daylight early in 1632.

Wargentin, the oval close to the moon's southeast limb, beyond Schickard, is a unique formation in that, instead of its interior being sunk below the general level, it is elevated above it.

For instance, Schickard, close to the south-eastern border, is nearly 130 miles in diameter, and its wall rises in one point to over 10,000 feet.

Grimaldi, almost exactly at the east point, is nearly as large as Schickard.

Schickard is one of the largest walled plains on the moon, about 134 miles in breadth.
