Party On

For a hands-on experience, we host our nightly star tours with telescopes including an 11-inch Celestron Edge11 HD. This telescope provides clear and focused views of many astronomy targets including the Moon, planets, and deep-sky objects such are large nebulae and galaxies. It is our primary instrument for visual astronomy.

Under the Hood

The Observatory's 16-inch aperture Ritchey-Chretien style telescope is designed with hyperbolic shaped mirrors like the Hubble Space Telescope, which offer an exceptional view of objects avoiding image distortions introduced by many other amateur telescopes. The telescope is perched on a precision-built Paramount mount which provides a great degree of accuracy while tracking celestial objects. This telescope is equipped with imaging equipment and focuses on capturing astro-photography imagery. Note: This telescope is designed and used for astrophotography which we share with guests. It is not used for visual astronomy during tours.


“Of all the sciences cultivated by mankind, Astronomy is acknowledged to be, and undoubtedly is, the most sublime, the most interesting, and the most useful. For, by knowledge derived from this science, not only the bulk of the Earth is discovered . . . ; but our very faculties are enlarged with the grandeur of the ideas it conveys, our minds exalted above [their] low contracted prejudices."
- JAMES FERGUSON, 1757
