Observatory Telescope

MacNaughton Observatory Telescope
The MacNaughton Building Telescope

The new telescope in our observatory is a 14" diameter, Schmidt-Cassegrain, Celestron C-14 mounted on an Astro-Physics GTO 1200 mount. The telescope has a focal length of 3910 mm, is f/11 without a reducer (f/7 with), and has four eyepieces available for use. The telescope is used by our astronomy classes in the fall and by the Astronomy Club.

Senior student projects, using our SBIG ST-9 CCD camera, are a further use of the facility. Astrophotography, and variable stars have been two recent projects.

How to get to the Observatory

  1. Go to the MacNaughton Building
