The Astronomy Club Cassiopeia e.V. Saarlouis, in cooperation with the Cultural Office Rehlingen-Siersburg, invites you on Saturday, August 27, 2022, from 8:30 PM to observe the starry sky on the Siersburg.
A highlight of the evening is the observation of our neighboring galaxy Andromeda. It is often also briefly referred to as M31 after its entry in the Messier catalog.
The Andromeda Galaxy is also referred to as the twin of our home galaxy, the Milky Way. The two galaxies are roughly the same size and are astronomically located in close proximity to each other.
Several club members will set up around 6 to 8 telescopes and enable all interested parties to observe objects in the night sky and explain them in an understandable way.
The equipment will be set up and prepared at 8:00 PM. After the sun has set, Saturn with its beautiful rings can be observed around 9:00 PM. Jupiter, which rises around 9:30 PM, shows the Great Red Spot until about 11:50 PM, a vortex storm discovered in the 17th century that is larger than the entire Earth. Those who wish to explore the depths of the night sky can observe various globular clusters, open clusters, double stars, planetary nebulae, and distant galaxies.
The ascent and descent to the Siersburg can only be done on foot, as the access roads are closed to vehicles. To ensure a safe descent, flashlights are recommended, but should preferably remain off on the castle plateau. Flashlights that are turned on should only be directed at the ground to avoid blinding anyone. Once you have adjusted to the darkness, you can see many more objects in the night sky with the naked eye as well as through a telescope. If white light enters the eye, this so-called dark adaptation is instantly lost, and it takes about 20 minutes for the eyes to fully adjust to the darkness again.
Interested parties who wish to set up their own telescopes are, as always, warmly invited.
If the sky is overcast, the event will be canceled.
