ATT Essen 40 Years - May 10th

Background: On Saturday, May 10, 2025, the 40th "Astronomy and Technology Meeting" (ATT) will take place in Essen. 

Beside the exhibitors the agenda for lectures is available with a lecture on remote astrophotography and
Die aktive Sonne in Foto, Time-Lapse und radioastronomischer Beobachtung by Udo Siepmann.

I'm looking out to attend this annual event.
