Abstract
In the present manuscript we consider the possibility of conducting SETI with
small-size (with diameters less than 1 m) optical telescopes. Calculations
are performed for typical parameters of the mentioned type of telescopes. In
particular, we show that the techno-signatures of Type-2.x and Type-3.x
civilizations might be detected. It is demonstrated that it is possible to
detect hot megastructures (up to 4000 K) built around Main Sequence stars
and pulsars, as well as von Neumann extraterrestrial probes.
期刊介绍：
Serbian Astronomical Journal publishes original observations and researches in all branches of astronomy. The journal publishes:
Invited Reviews - review article on some up-to-date topic in astronomy, astrophysics and related fields (written upon invitation only),
Original Scientific Papers - article in which are presented previously unpublished author''s own scientific results,
Preliminary Reports - original scientific paper, but shorter in length and of preliminary nature,
Professional Papers - articles offering experience useful for the improvement of professional practice i.e. article describing methods and techniques, software, presenting observational data, etc.
In some cases the journal may publish other contributions, such as In Memoriam notes, Obituaries, Book Reviews, as well as Editorials, Addenda, Errata, Corrigenda, Retraction notes, etc.
