This 25 inch, f/15, classical Cassegrain telescope with an equatorial fork mount is located in a 22 foot diameter dome. This scope has recently been computerized with high resolution encoders, stepper motor drives, and custom software to give it a comprehensive "go to"capability. A PC, resident to this scope, contains star chart and catalog. Pointing to the desired object will automatically position the scope to that object. The scope also has a 5 inch Clark refractor and a 50mm finder. Cora Zemlock was a long time member of the MAS who donated the money for the mirror for this scope. She later left a large endowment fund that has supported the MAS for many years. Close-up of the Zemlock Telescope Get Your Own Visitor Globe!
