Abstract Recent measurements of the UV atmosphere glow have reported bright and fast Transient Luminous Events (TLE) in the atmosphere. Some of TLE features related with its space image and temporal characteristics remain unclear. The pinhole camera designed for observation of EAS Cherenkov light (Garipov & Khrenov, 1994) could be applied for TLE imaging with high frequency needed for revealing the TLE origin. In this work, we present a design and calibration of a pinhole camera aimed for TLE observations from the mountains. The TLE images are recorded by Multi Anode Photomultiplier (MAPM) tubes in two configurations. The electronic design of the camera including an automatic gain control for each MAPM tube is presented. The pinhole camera was calibrated by observing the moon light of various phases from the top of Sierra Negra Volcano (4300 m.a.s.l.).
