The Kovac Planetarium east of Rhinelander has opened for the season. If you travel about 20 miles east of Rhinelander on Hwy 8, you will see their sign. Frank Kovac bills his attraction the world’s largest mechanical planetarium.
I was fortunate enough to get a private showing from Frank about a month ago. It was an excellent show! Frank is very knowledgeable about all things having to do with the planets and stars.
