Solar Eclipse 2026-08-12 in Aragón, Spain

Preparations for this eclipse started already in 2019, when I first visited the villages of Cetina and Sisamon. The villages are just a few kilometers apart and are located between Madrid and Zaragoza. Especially the vicinity of Sisamon profed to have great spots for night time observations, as light pollution is pretty low. The same spot I observed in 2019 was also a perfect spot for the solar eclipse, as it lies approximately 1000m above sea level in a high plane. To the west, only some distant hills are seen, reaching 2 degrees above the horizon at maximum. This was crucial, as the totality would happen with the sun being only 7 degrees above the horizon.

Thanks to the mayor of Sisamon and my sister in law to communicate with him, I got the permission to setup my observation base at this very location. He also supported me in having my complete equipment without any obstacles and disturbances, despite a good 100 locals joining the event. They were all essential for the emotional experience, as many of them started cheering and shouting when totality arrived.
A big THANK YOU to everyone involved to make this a perfect day!

According equipment, my primary goal was to get the shots for the Eclipse Mega Movie project (a Sonoma State / NASA project, I participated the third time). Then, some overview and especially landscape views of totality were on my plan, to also showcase the shadow of the moon.

Active sun – quiet sun

The sun follows a regular cycle of activity and quietnes. This cycle takes 11 years to start over again. By chance, the 2017 total solar eclipse was at the solar minimum and the 2024 total solar eclipse was at the most active phase – the solar maximum. Comparing the images I took during totality of the two eclipses, the solar corona also reflects this.

During the solar minimum, the corona looks more structured. At the poles, the corona shows a well defined pattern resembling the magnetic field lines.

In contrary, during the solar maximum, there are more jets and streamers (also at the poles) but there are less structured patterns. Especially the inner corona looks rather chaotic compared to the quiet sun.

It will be fascinating to compare these images with further images from other eclipses…

Total Solar Eclipse USA 2024-04-08

The main reason to travel to the US and go on a road trip to follow almost the entire golf coast from east to west was to see and photograph the total solar eclipse on April, 8th.
My plan was to image with a total of 9 cameras. Most of the cameras got a custom made (see my 3D design here: https://www.thingiverse.com/thing:2431974) flip-away solar filter, to facilitate the on and off during totality. As I was up to share my photos with the scientific community through the Eclipse Mega Movie project, like in 2017 (https://eclipsemegamovie.org/), I had some constraints to follow for my setup.

Therefore, the complete setup, which should be mounted on 4 independent tracking mounts, was:

Sony A6000 full-specturm modified with 80/600mm APO
Sony A6400 with 72/435mm APO for longer exposure sequences
Sony A6400 with 72/435mm APO for shorter exposure sequences
Sony A99ii with 35mm lens to capture the eclipsed sun with planets and hopefully a comet
Sony A58 with 135mm lens
Sony ZV-E10 with 100/1000mm maksutov
QHY485C with 50/242mm APO for a totality video
2 GoPro cameras for scenery

With bad luck, the airline was incapable of delivering one piece of luggage with my primary tracking mount within almost 3 weeks. Therefore I had to reduce the actual setup for the eclipse day in parts. Furthermore, it was quite unsure, whether observing the eclipse was even possible. A wide stretched cloud system covered large protions of Texas. In the morning, there was not even a patch of blue sky visible. Luckily, the clouds got less and less and even the one cloud covering the sun a few minutes before totality moved away. So we finlly could observe the eclipsed sun with an almost perfect sky. In the end I was able to record the required images, totaling to more than 400 GB of data.

Total Solar Eclipse in Turkey 2026-03-29

It has been a bit more than 6 years since I could see the total solar eclipse in Austria (11th August 1999), when I found an advert for an eclipse trip to Turkey for March 2006. The amateur astronomers from Viennese Astro-Station-Conrad organized this tour, where more than 300 enthusiasts and eclipsophiles participated and travelled to a hotel near Side. The holiday resort at the mediterranean sea was perfectly placed in the path of totality.

Since I first saw prominences through a telescope with hydrogen (H-alpha) filter, and results from the 1999 eclipse were mediocre (I only had a tripod and manual trigger), my dream was to capture prominences during the eclipse. For good results, a tracking mount is required. I onyl had a shaky EQ2 mount, which is built for telescopes with up to 4 kg. My initial plan was to use 2 cameras. Though I could further borrow a third camera as well as another mirror lens.

But how to mount these three cameras? I could not find a base supporting 3 cameras – especially none suitable to attach to the EQ2. I came up with an aluminium frame and pipe clamps from the hardware store. The contraption is definitely unconventional. The total weight put on the EQ2 is also way above the specified limits. Luckily, there were no major issues. Only the little motor struggled from time to time to keep the gear coupling.

The setup:

Minolta Dynax 7, Sigma 135-400mm f/4.5-5.6 DG APO @ 400mm
Konica-Minolta Dynax 7d, MC MTO 11CA (1000mm mirror lens)
Canon 20d, MC MTO 11CA
