Hello Andrei,
welcome to this forum !
I see that Ruediger already mentioned Volkssternwarte München (Munich public observatory) with a link. I'm also a member, and a visual deep-sky observer. We are a club with many amateur astronomers, and also offer guided shows for the public.
I send you a private message with the eMail-address of a very experienced astrophotographer in our club. He is looking forward to contact you 
Greetings
Ben
