Jupiter - 20.1.2015 at 22.21 Tyrnävä Observation number 33148

Visibility IV / V

Jarmo Moilanen, Ursa (Pohjois-Suomi)

A random picture of Jupiter. I was filming the comet Lovejoy and at first I looked into the condition of the focus. Jupiter shone in the sky, so I focused on it. As I focused, I suddenly noticed two of its moons next to Jupiter on the camera screen. At the same time, I flipped this picture with the settings on the camera.

The cliff is on the lower left and Ganymedes on the upper right of Jupiter. At the time of filming, Io and Europa were still inside the glow of Jupiter. They are on the same side as Ganymedes. Just a few minutes earlier, Europa has left the front of Jupiter's disk.

The exposure went well over, so the image is not technically good at all. Somehow just amused by this 50mm lens (75mm cinema equivalent) picture of Jupiter and its moons.
