Other Events

The CAS sponsors free telescope observing sessions at various sites. Everyone is welcome to attend.  This is a wonderful opportunity for boy and girl scout groups or school groups.  If you ever wanted to view the night sky through a telescope then pick a date from below.  Usually CAS holds its monthly meeting on the Second Friday of each month at Adler Planetarium.  Non-members are welcome.

Do you want to make the optics for your telescope? Call Jim Seevers at (219)902-1817 for details.  The optical shop (which once was operating at Adler Planetarium and recently donated to the CAS by Adler) is located at 3511 Illinois St. in Lansing, IL.
