 Milky Way
The Rooisand 3.2m dome under the Milky Way

Image data:

The widefield image shows the tower of the Rooisand observatory with the bright center of the Milky Way in zenith. In real life - with a clear sky this is a truly amazing view.

Over the mountains of Rooisand, the center of the Milky Way rises behind a green layer of Airglow.

The Big Dipper culminates just over the northern horizon and appears upside down for observers from the northern hemisphere. The orange glow on the horizon on the right side is caused by illuminated clouds over Windhoek, which is nearly 130 km away. The greenish glow over the whole sky is a very low emission of the atmosphere, called Airglow. In combination with the light from the stars and the milky way, the Airglow results in a faint illumination of the ground. So, even under an open night sky, the night is not black. Some brighter deep-sky objects are annotated here.

Rising of the Magellanic clouds

Both Magellanic Clouds came up exactly in the middle between the high palm trees of the Roisaand Desert Ranch.

After the observation of the zodiacal light at the Onjala Lodge in April, we were able to observe the Gegenschein (counterglow) - another effect of interplanetary dust. The Gegenschein is located directly opposite the sun and is caused by the backwards scattered sunlight. It can be observed as a weak, oval brightening during a very dark sky.

At first we was not really sure whether the oval spot was maybe an extension of the Milky Way, because the Gegenschein was still relatively close to the Milky Way at this time. But the location within the ecliptic was a strong indicator for it indeed to be the Gegenschein. Additionally a clearly visible zodiacal light (mainly caused by forward scattered sunlight) could be observed on the other side also indicating a very dark sky. The examination of the wide angle image nicely demonstrated that the zodiacal light was present along the entire ecliptic - starting from the light cone in direction of the sun (right side of image) via the very faint light bridge towards the Gegenschein, which fades over to the Milky Way on the left.
Activity during mounting the new equipment in the Rooisand dome

Night time activities during setup of the new instruments at the Rooisand Observatory. Originally a video was planned, but the exposure were just too short to get a good result. That is why there is just the startrail. The both descending objects are the moon (at the very bottom) and the Venus above.

View from the Rooisand Observatory to the southern celestial pole. At the beginning of the image session the foreground was illuminated by the setting moon and appears in a warm red light.

The image was created at the last evening at Rooisand and shows the trail of the car going back to the farm while the camera was still taking pictures.
