            Background
Group 128 16-inch Cassegrain telescope in
Physics
Purpose: For teaching public outreach and
research
Used in ASTR 3005, 4005 and 4006
More than 12,000 visitors
Used to study the comet Hale-Boop
Computerize efforts

 Limitations of the telescope
Interface failure
Manually observations
    Naked eyes observations
Number of observers
Fails meeting instructional and research
purposes
Stills using old technology!!!

        Proposed Solution
Problems to address
    Control System Interface to the telescope’s
    equatorial mount replacement
          Alternative Funding
    Ability to conduct observations from a remote
    station
          Data collection simplified
          Real-time images
          Multiple observers
    Old Technology challenge
