It’s unfair that Americans pay the highest prescription drug prices in the world! Tell Congress to stop Rx greed and cut drug prices now.    

Detwiler Planetarium

Lycoming College, 700 College Place
Williamsport, PA 17701


The College's Detwiler Planetarium is used in our astronomy classes, and astronomy majors can be trained to operate it to give shows to outside groups. Currently, the planetarium has a 30 foot dome with optical-mechanical star projector. Plans are in the works for a totally new planetarium which will be a optical-mechanics/digital hybrid projector. Some of our astronomy majors go on to operate planetariums in a variety of settings after graduation. Additionally, the department has several portable optical telescopes that students frequently set up on campus and may also take off campus for better observing conditions. Along with our astronomy program, we also have a geology laboratory with rock, mineral, and fossil samples collected from all over the country.
