The Allen F. Blocher Planetarium
and The Arthur J. Pejsa Observatory


Both the Allen F. Blocher Planetarium and the Arthur J. Pejsa Observatory are located in the Science Building on the UW-Stevens Point campus.  The Science building (2001 Fourth Ave) is at the southwest corner of Fourth Avenue and Reserve Streets. 

The planetarium consists of a 7.3m diameter dome that houses a Spitz 1024 projector (installed in 1998).  The planetarium is located on the second floor of the Science Building directly above the east main entrance.  The planetarium presents public programs through the academic year and during most summers.  There is no charge for our public programs.  Planetarium programs for groups (schools, scouts, organizations, etc.) can be arranged during our academic year and our summer sessions.  There is a $25.00 charge per group for these presentations.  Usually the planetarium is closed from 24 December until late-January and during August.

The observatory is located on the fourth floor of the Science Building and houses a Meade 0.4m telescope.  The oblservatory is only open if the skies are CLEAR.  Normally, the observatory is open on clear evenings Monday through Wednesday when university classes are in session, Normally this is from mid-September to mid-December and from late-January to mid May.  Most summers the observatory is closed. 

The planetarium and observatory are closed during the University interim and break periods. For current updates please call the Planetarium/Observatory at (715) 346-2208.

These facilities are operated and maintained by staff in the Department of Physics and Astronomy at UW-Stevens Point.
