What a wonderful experience to be able to look through the same telescope that has been so instrumental in the pioneering of modern Astronomy. Our host and guide Dan Koehler was so incredibly informative and helpful. An amazing experience that I will cherish forever.

I first set eyes upon the amazing 60 foot refracting telescope at Yerkes more than 40 years ago. Just being inside the dome with this massive, historic piece of equipment is awe-inspiring. There’s much to learn from the $8 general public tours alone (daytime). But...More
