EN 40th ATT anniversary 2025
19.05.2025
We would like to thank all visitors, exhibitors, and helpers who contributed to the success of the 40th ATT. Thank you for your loyalty over the years!
As previously announced, a commemorative publication was published for the 40th ATT. It contains a retrospective from the perspective of exhibitors, visitors, and us, the Walter Hohmann Observatory in Essen. For those who were unable to attend the ATT in person, we are happy to offer our brochure as a download.
Good luck and clear skies!
See you at the 41st ATT on May 9, 2026.
