Astronomy lecture-crater Biela-telescope images

Biela crater (76 km), is a lunar impact crater on the rugged highlands of the Moon's south-east and has a depth of 3.1 km. The crater is east of Rosenberger, and south-east of the Watt-Steinheil double craters.

 The rim of the crater is covered by a pair of small craters, but notable: Biela C (26 km) on north-east edge and Biela W (16 km) along the western inner wall. Biela B crater (43 km) is attached to the outer edge of the southwest. Biela's edge remains relatively well-defined, especially in the southeast.

The interior is flat and without notable small craters on it. There is a central peak formation, three ridges located to the north-east of the midpoint.

Biela, was named after Baron Wilhelm von Biela,-( Wilhelm Freiherr von Biela ), (March 19, 1782 - February 18, 1856) which was a German-Austrian officer and an amateur astronomer.
