Starscape image

1.5.2022 at 23.38 - 23.39 - Helsinki (III)
Tuomas Salo, Ursa (Helsinki)

I photographed a landscape constellation with a rocket apparently fired from the east at the top. The timestamp of the first image was 23.38.23 and the timestamp of the second image was 23.39.44, with a time difference of 81 seconds. By that time, the rocket had already exited an image taken from the same point in the sky. The triangularity of the target also refers to the flue gases of the rocket. The exposure was 15 seconds in each image. The camera had noise reduction turned on.
