Birt crater and other features on the Moon, also Rima Birt - a slightly curved ~50 km long channel that starts and ends in a pit. Photo: Georgi Georgiev, Stara Zagora, Bulgaria. Since this is a telescopic view, this image is inverted.
Birt is a lunar impact crater located in the eastern half of the Mare Nubium and west of the Rupes Recta, further west is Nicollet and south-southwest is the smaller Lippershey.
Birt is a bowl-shaped formation with a raised rim, slightly intersected along the southeast edge by the much smaller crater Birt A. To the west of Birt, a rille named Rima Birt runs north-northwest in an arc from Birt F to Birt E.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Birt.
