The observatory is both a school and public observatory. Lectures are arranged for pupils at various levels as well as courses for teachers. Since 1959 astronomy has been a compulsory subject in schools in the D.D.R. (one of only four countries in the world in which this is the case). The observatory also participates in scientific work, particularly in the field of variable stars, where it has always had very close links with Sonneberg Observatory.
