Currently Mars is shining brightly in one of the most intriguing parts of the Milky Way. The picture shows Mars (the orange dot in the left hand corner) along with the Lagoon Nebula ( red cloud below Mars), the Trifid Nebula (small red-blue dot to the right of the Lagoon Nebula), the Omega Nebula (red dot to the far right) and the Eagle Nebula (in the lower right corner). Also visible are a number of star clusters, the most prominent of which is the globular cluster M22 (the bright white dot at the upper edge of the image).
Tonight I caught the waxing moon, 6 days after new moon, with 14% of the disk illuminated. This shot was taken through a telescope with at a focal length of 1600 mm.
I was taking images of the zodiacal light or false dusk (a triangle of light that is visible in the West just after sunset during springtime in the Southern Hemisphere), when a bright meteor illuminated the scene, only missing Saturn by a hair.
Scorpius and the planets Mars (brightest dot in the upper left hand corner) and Saturn (bright white dot almost straight below Mars) one day after full moon. The image was taken with a special diffuser filter to highlight the colors of the stars and planets.
Finally El Niño gave us a break and we had a spectacular clear night, which I used for some wide-field images of the Milky Way. The bright red dot above the Milky Way is the planet Mars, the fainter red dot below it is Antares (the main star of the constellation Scorpius), and the brighter dot to the left of Antares is the planet Saturn. The images were taken with my camera sitting “piggyback” on a telescope with motorized tracking.
On May 9, 2016, the planet Mercury passed directly in front of the sun (visible as a small black dot on the sun’s face). The whole event lasted seven and a half hours. However, in this part of Chile the initial stages (first and second contact) took place shortly before sunrise, and were therefore not visible. We had quite some clouds on that day, but I was lucky and could watch and photograph most of the transit. Transit in progress; Mercury and sunspots. Mercury is leaving the sun’s disk (third contact). A 100 % crop of the above picture. Sun halo during the transit. My setup for the transit (8″ TEC APO, 1600mm, f 8, Baader AstroSolar Safety Film).
The Polloquere hot springs are located at 4318 meters in the Salar de Surire in northern Chile (Parinacota region). This is a very remote area that can only be reached by offroad vehicles on rather precarious roads (don’t forget to bring extra gas and lots of water). The thermal water is moderately to very hot, and thus perfect to warm up in cold temperatures. During our stay at the hot springs we had a full moon. Although this is not ideal for astro photography, it nevertheless illuminated the landscape nicely and gave the sky an appealing blue tint. Rise of the full moon. The two brightest stars of the nightsky, Sirius (right) and Canopus (left) are setting. The Big Dipper, but on its head. Great campsite with lots of parking available. Frozen windows in the morning. Moon setting. Sun rising. The moon is setting behing the ridge on the right, while the first rays of the sun illuminate the mountain on the left. Lovely morning scenery.
I was very lucky and could to join a daytime visit to the Atacama Large Millimeter/submillimeter Array (ALMA). ALMA is located at 5000 meters altitude on the Chajnantor plateau in the Atacama desert. It consists of 66 high-precision radio telescopes, that have a diameter of 12 and 7 meters, and that can be spread over distances of up to 16 kilometers. ALMA is used to study light from some of the coldest objects in the universe, thus providing insights into our cosmic origins. In order to reach the ALMA high site you have to undergo some rigorous medical checks at the OSF (Operations Support Facility) located at 2900 meters and endure a bus ride, which completes the ascend to 5000 meters in 45 minutes.
