For the German Astronomietag on March 24th, I packed the dobsonian telescope and lots of other things into my car and headed for Berlin. On Friday, 23rd we planned to finally assemble the telescop and prepare for presentation.
Good news first: We are ready for Astronomietag! Adjustment of the optics is finished, the trusses have correct length, first light successful finished.
The second day started at 9 o'clock. Even before breakfast, we had assembled some more parts to determine the potential need for additional screws and metal parts. Then one came to the other.
We spent the first weekend in March in Berlin, exactly according to the project plan, and started building the prototype.
