The 18" Dobsonian is in a roll off shed. Completely low-tech, this scope provides the intuitive ease of control inherent in the Dobsonian design. A long time member, Dick Wiesen was president of the MAS for many years and an active deep sky observer. He particularly enjoyed the MAS campouts and dark sky outings. The purchase of this scope was inspired by memorial donations in Dick’s name. Get Your Own Visitor Globe!
