10 full nights under the pristine Fall skies of La Palma

With the core of our own galaxy, the milky way, disappearing under the horizon, the Fall sky might seem boring at first glance. Think twice about it: colorful airglow, meteor showers, myriads of colorful nebulae and easy-to-spot deep-sky objects, zodiacal lights, satellites and much more... That's the daily spectacle I bought tickets to for ten days, in one of the darkest places on Earth. Are you ready for a jaw-dropping space show?


Four and a half hours a day… That’s how long I have slept each day for ten days. Why would I bother being deprived of vital sleep though? Because my mission and goal was to show the night sky in a different way. The second opus of my sequel ‘Galaxies’ aims at finding new techniques and skills to bring the beauties of the cosmos to the general public, and in this optic, I went to spend a bit more than a week in a privileged place: a dark sky reserve. La Palma is located in the Canary Islands, just a few hundreds kilometers west of northern Africa. Its climate and location enable professional and amateur astronomers to gaze at the stars almost year round in a very little light polluted sky. In fact, the cooperation of more than 19 countries in building a giant observatory site on top of its volcano at 2400m is no surprise, because the skies are drier, purer and darker up there. Having shot on top El Teide in Tenerife- the neighbor island, two years before (See video below), I thought it was the perfect place to go shoot the wonders of the winter night sky. Tenerife also possesses decent skies and opportunities to gaze at the core of the milky way, but when your goal is to observe and capture fainter deep-sky red glows, you need a less polluted and bright atmosphere. That’s why I embarked for an epic and restless astro-adventure on Canary’s darkest island.



Epic and restless, because the objective was to spend all night shooting. So I have done! Every evening I would drive one and a half hours from sea level to 2400m of altitude along the dangerously winding coastal roads to arrive at the top El Roque de Los Muchachos, the volcano. The air is very thin and chilly up there, not to mention the constant wind gusts, making any kind of portable time-lapse astrophotography challenging. I would start shooting from dusk till dawn in the dry cold air, and rest in my rental car while my cameras are shooting. At the break of dawn, I would drive down to my holiday condo and sleep for about 4-5 hours. I needed to get back up, because no matter how much I planned the trip before hand using google Earth to find good shooting spots, you need to scout during the day, otherwise you won’t get a chance to see anything. If you don’t know what dark is, I advise you to get up there. It is so dark because of the basaltic nature of the island's rocks, that almost none of my sequences are taken below ISO 6400 and 10 seconds of exposure, no matter what the focal length is. You need all the light you can gather!


For example, I took this stunning vertical panorama of the milky way setting on the Observatorio del Roque de Los Muchachos along with Saturn (yellow dot), Lagoon nebula (pink dot), Scutum (shield constellation) and the pyramidal slanty beam of white light across the milky way emerging from the western horizon: the zodiacal lights. In order to get such an detailed shot, I needed to climb the rocky mirrador along the crater ridge (the Observatory was closed at night!). Then, I needed a close-up lens to get as much detail, and shoot consecutive images that I would stitch together later (6 in total). On top of that, I used a tracker to compensate for the rotation of the Earth and get pin-point stars! I wouldn't have been able to get that much contrasts and details it it hadn't been for the quality and darkness of these skies!




La Palma is extremely beautiful and weird at the same time. The island is sort of divided into two parts. The first one to the east is the one I didn't go to much, as the road going up the volcano is very dangerous. It receives warm and humid air rising up from the Sahara above the 100km of sea that separate the island from Africa. This causes the east coast of La Palma, and subsequently the eastern slopes of El Roque, to be almost like Hawaii: hot, lush green and extremely humid. Conversely, as the volcano stands in the middle of the island, it blocks all kind of low cloud bringing humidity to the other side. The Atlantic ocean's influence to the west also brings clouds and thunderstorms, but the low clouds seem to magically disappear encountering higher pressures and temperatures from Western Africa, so the west coast gets very little rain. It causes a major change in the fauna and flora from east to west. In the latter, it is very hot and dry, almost like a mediterranean climate, with lots of pine trees, cacti, grassy rocky slopes (Photo above).

Now why would I go spend 10 straight days on a cold and windy volcano if the bright side of the milky way isn't there anymore? Besides, the rest of the island is almost constantly under a blanket of boiling low clouds, so you wouldn't even be able to enjoy swimming or sunbathing... Well, because the 'dark side' of the milky way, what we call the 'winter side' (because it is visible in the winter) holds a great deal of other interesting objects and events, and I wanted to include a maximum of them in my upcoming movies with the gear and time I had with me.
