If you catch a good moment, you can find the International Space Station in the sky without the use of instruments. It resembles a tiny bright spot moving across the night sky.
You can spend time on your own searches or admire the amazing work of astrophotographer Shabolch Nagi. He managed to fix the flight of the ISS in front of the Moon. He was lucky that on February 10, the London sky cleared up and managed to capture an amazing sight.
Nagi uses a special astronomical calculator to track the time of various events. The program also indicates where the observer should be located in order to be on the center line while the ISS is in the middle of the observation. Such videos and photographs attract the attention of scientific skeptics who do not believe in the existence of the ISS, satellites and space flights. Astrophotographer's Twitter is filled with comments from flat-earth supporters.
Some seriously demanding to provide evidence of the existence of an orbital station. Nagi advises such people to simply acquire a telescope, and independently explore the sky. He assures that own observations allow changing the views on the Universe.
