Star lost

This is from Kris McCallon October 21:

"My heart goes out to all of you there at YSU. While there is no way I can possibly know what you and others are feeling, my thoughts and prayers are with you. The planetarium community has lost another star, but he will continue to shine on through the work he did there with you.

Peace, Kris McCall, Sudekum Planetarium, Nashville, TN"
