Chasing darkness in Greece – Karpathos

Like every summer, I packed the telescope, mount, camera and many accessories and flew to Greece. This time we went to Karpathos, the island not spoiled by massive tourism and light pollution. Long story short, the skies were amazing, but every single night, except one, was extremely windy. It was a torture – to see millions of stars and not be able to photograph them. There is no surprise that Karpathos is beloved by windsurfers and kite surfers. In the end I captured only the Iris Nebula and the Double Cluster. I talked to locals and they told me that the wind should stop at the end of September, so probably I picked the wrong time.

On the other hand I was able to do a wide angle astrophotography of the Milky Way. SQM reached 21.5, galactic core was so bright and I think the photos of the Milky Way are quite decent. This time I changed the setup and purchased Canon EOS 6D, which is one of the best cameras for this purpose. Moreover, there are many second hand 6Ds, because mirrorless mania arrived. 6D combined with Samyang 14 mm f2.8 offers excellent performance for this purpose.


Chasing darkness on La Palma

All of my previous dark-sky expeditions were organized in summer-autumn part of the year. At this part of the year shines the galactic core of the Milky Way during the night (only if the sky is dark enough) and there are many deep space objects available. During my expedition to Milos I managed to capture huge part of the Messier catalogue. However, there are some deep space objects, which are badly visible from my home and which have to be captured in the spring. I was researching where can I spend few days, preferably somewhere south and even more preferably under dark skies. Googling yielded in brilliant idea – La Palma, Canary Islands. This island belongs to three most prominent spots on Earth for astronomy (together with Mauna Kea in Hawaii and European Southern Observatory in Chile). The observatory on La Palma is called Roque de los Muchachos and currently there is the largest optical, single aperture telescope on this Planet (The Gran Telescopio Canarias). The observatory is built on the highest mountain of the island at altitude nearly 2500 meters above the sea level. On the whole island there are strict rules for the street illumination, therefore the dark skies are not the privilege of the highest mountains, but nearly everywhere are the conditions great, maybe except two big towns – Santa Cruz de La Palma and Los Llanos. Dark sky is probably the same touristic attraction on La Palma like the beaches on Greek islands.


Chasing darkness in Schwarzwald

My second expedition after the dark skies (this year) led us to Germany, specifically to Black Forest (Schwarzwald) in the state of Baden-Württemberg. We rented a small cabin for a weekend and I took the same equipment which I took to Milos, i.e. telescope newton 150/600 mm, mount iOptron CEM25P and ZWO 071 Pro camera.

As soon got dark, the Milky Way showed up. I measured SQM and it reached 21.1, which is not spectacular, but far better compared what I have at home.

The equipment was working perfectly, but the dew started to form on the secondary mirror, because the cabin is close to river Breg, which means a lot of humidity. I never had dew problems with Newtonian telescope up to now. Lessons learned – I need a dew shield. I managed to capture only M74 Galaxy and M78 Nebula.

Anyway, I also managed to capture wide angle photos with my Pen-F and Fish eye lens.

Here are the star trails – exposure 30x30s:

And here is the Milky Way – exposure 1x30s ISO 3200 f1.8:


Chasing darkness in Greece – Milos

My second expedition after dark skies led us to beautiful island Milos. It’s mid-size island in Aegean see and it belongs to group of islands called Cyclades. The port and whole night life (bars, restaurants, discotheques) are located on the northern part of the island. We stayed on the other part of the island, where are empty, not organized beaches and mainly very low light pollution. To travel there is not straight forward, because Milos has very small airport. Therefore we had to fly to Santorini Island and from there take a ferry to Milos.

Chasing the darkness in Greece on small island Gavdos

I was always dreaming about dark skies, because I live in sub-urban area with relatively strong light pollution. Two friends returned from Gavdos where they spent their summer vacation and told me that they have never seen so many stars in the sky – at that moment I was tempted. One year later I decided to combine our summer vacation (mid Semptember) with chasing of the dark skies. Swimming, snorkeling, hiking during the day and photographing, observing during the night.

We have been to Greece already, so we knew what to expect – beautiful beaches, people with great hospitality and tourists everywhere. But Gavdos is something different. It is a small island south from Crete. The island is the southernmost point of the entire European continent, which is optimal for astrophotography, because the deep space objects, which are near to the horizon in Switzerland, are 12° upper in the sky. Only few people live on Gavdos, which means there is no light pollution compared to other Greek islands. There are neither big hotels, discotheques nor organized beaches. On the other hand there are places where you can sleep and there are many taverns where you can get something delicious. Moreover in all taverns is a Wi-Fi. Electricity is mostly produced by the solar panels and stored in the batteries and some taverns use generators, so there is electricity available whole night. This means you don’t have to carry heavy batteries to power the mount or camera cooling with you.
