  Consultation on base of collaboration with following institutions

As editor of the magazine SPEKTRUM since 1994, I offer with this newspaper for amateur astrospectroscopy a comprehensive opportunity and possibility for studying and publishing around the practice in amateur spectroscopy. In this magazine amateurs reports of practical activities within the fascinating field of astrospectroscopy. SPEKTRUM (ISSN 1869-4454) appears half-yearly in April and October. In case of any interest, write an email: ernst-pollmann (et) t-online.de
