Comet NEOWISE (C/2020 F3 NEOWISE) and a California redwood tree 7/18/2020 @22:00 PDT, from the backyard, Sunnyvale California USA. The equipment is Sigma 150-500mm zoom at 150mm with Canon EOS 6D, mounted on Star-Adventurer, and the camera setting is 5 seconds exposure, ISO1600 F/5.0. Photoshop CS5 is used for processing. 明るいコメットなので、にわとり。街灯とご近所さんの門灯の光を避けるのに四苦八苦。
