This 100-second-long image of the globular cluster M53 (NGC 5024) in Coma Berenices was captured remotely on April 29, 2013, using the Bradford Robotic Telescope's 14" f/11 Celestron C14 SCT and FLI MicroLine camera located on Tenerife in the Canary Islands. A Celestron focal reducer yielding an effective focal length of 1877mm at f/5.3 was employed.
