M53 (NGC 5024) Globular cluster
Sketch and Details by Kiminori Ikebe, translation by Mr. Eiji Kato

This is a globular cluster southeast of Mel.111 in Coma Berenices. It is fairly large and even at 110x it is finely resolved. This is a beautiful globular cluster with individual stars appearing as pinpoints.
The core shows even brightness and stars are well resolved to the center. North of the center there is a double, but they do not seem to belong to the cluster. The outlying regions in the northern half show scattered faint stars. The southern nebulosity does not show this.
