(CBS) — A retired business owner says he’s not an astronomy fan particularly but he’s donated enough to help finish the new observatory being dedicated Wednesday night at Niles West High School, reports WBBM’s John Cody.

93-year-old John Slater said while he’s not an amateur astronomer, he does cast his gaze skyward now and again toward his favorite constellation

“The Big Dipper because of its utility in finding the North Star is my favorite,” said Slater.

Slater said he liked the way Niles West High School involved both the astronomy students and the community so he donated $70,000 to increase the size and advance the opening date for the two-story domed observatory with a grand opening at 6 p.m. this Wednesday at 5701 W Oakton in Skokie.
