Citing of an UFO travelling from one star to other.I was on the roof of my home where I was capturing shots of the city. After few shots I decided to capture the stars when I noticed a UFO. The UFO almost appeared like a bright star (could be confused with a flight) but I think it was travelling faster than expected. The UFO travelled between two stars and then vanished completely. In the image I captured one could notice a trail of light from which experts can confirm if it was an UFO or not.Also, after capturing the image I made note of the two stars using "star tracker" app on my smart phone.The image was capture using following settings Camera: Nikon D5100 F-stop: 3.5 Exposure time: 30 sec. Focal length: 18 mm
