I retired in May 2012, so the April 27, 2012 astronomy open house was the last one I'll be presenting for now. I have not completely ruled out doing other shows in the future, but will not be making any decision about that until the end of 2012; so the earliest any additional shows might be presented is Spring 2013. However, Professor Mike MacCallum and his lab classes will be presenting separate planetarium shows and telescope open houses during the Fall 2013 semester, and I will post a link to his schedule as soon as I know where it will be posted.
