Welcome to the Osten Observatory on the campus of Concordia University in Seward, Nebraska!

The observatory supports a Meade LX-200 16" telescope in a Sirius Observatories 10-foot fiberglass dome.  Students and faculty host regular public viewing in the spring and fall, and use the Meade DSI CCD and Celestron NexImage5 imagers for photography and research. 


  • The next public viewing will be Tuesday September 1, 2015 from 9:00 - 10:30 pm.  Come out and see the Ring Nebula, a pretty double star, a rich globular cluster and a nearby galaxy!
  • There is now abundant parking in the new HHPAC parking lot just west of the observatory!  Please do not park on Hillcrest.  There is an illuminated path from the parking lot to the observatory.
  • Please note that in the fall we will be having one open house per month in September, October and November. See the "Events" page for details.
  • We have had several questions about an email saying that August 25 would be a great night to view Mars.  Unfortunately, this email is a hoax.  There was a great viewing of Mars on August 25, 2002 (where we had over 400 people see it through the telescope!).  Since then the email has re-circulated every year, but with the year removed from the date and with details becoming more and more enhanced.  Please see this NASA page and this page from Snopes about the Mars Hoax.
