Astronomical Society Orion (AD ORION) is the successor of the University Astronomical Society Sarajevo, which was in operation from 1963 to 1992. Bosnia and Herzegovina in that period had extremely developed astronomy for the standards of the time, especially if one considers that before that there was almost no tradition or people who where professionally engaged in this science. Astronomical Observatory at Trebevic was the shining beacon of a new era in the former state, and the echo of those events is also present today in oral and written memory of many. For the generation of astronomy lovers in this region, many of which in the meantime have become professionals, Sarajevo represented a window in space available to all.

The work of the pre-war Astronomical Society was restored in 2008. In the previous period the most important activities and projects were:

• The “Activities to mark the International Year of Astronomy 2009 (IYA2009).” The project was realized in the second half of 2008 with the help of the Federal Ministry of Justice;
• The project “1000 Galileoscopes for 1,000 schools in BiH – One sky for all”. (Financially supported by the Norwegian Embassy in Sarajevo and the Ministry of Civil Affairs. Logistical support was provided the NATO forces headquarters in Bosnia-Herzegovina);
• Courses in general astronomy;
• School of astronomy for children
• The establishment of the Bosnian-Herzegovinian Meteor Network in cooperation with the Federal Hydrometeorological Institute. Currently in operation there are 7 stations supplied with video cameras. The results so far are impressive.
• Public observation of the sky
• Public lectures
