Hello Andrej, hello Tal,

Our telescope making and mirror making group meets every Tuesday:

More Info of this group: https://www.stathis-firstlight.de/spiegelschleifen/matm.htm
Of course the main focus is telescope making, but we discuss all related topics as well. We speak German and sometimes Bavarian 
, but almost all of us can speak Englisch as well.
When it comes to nightsky gatherings outside München, things become more delicate theese times.
We would be glad to see you in the club.
