The Duke Teaching Observatory, founded in 2002, is an observational facility designed with two missions:

Find information on the history of the observatory at the previous website.


The observatory currently operates five Meade LX200 GPS Schmidt-Cassegrain telescopes. For details on the telescopes, check out the user manual or the assembly instructions. Housed in a shed on-site they are assembled for each session. Nine piers, with power outlets, have been installed to encourage visiting observers to set up their own equipment. Located in the Duke Forest, the observatory is operated and maintained by the Duke Physics Department as part of our overall educational outreach effort.


The observatory is regularly used by students in Physics 55, the undergraduate introductory course in astronomy at Duke. To the extent possible, it is open on roughly alternate weekends for free public viewing. Check the schedule at top of page to see when these are available. The site is also used by CHAOS, the Chapel Hill Amateur Observation Society, for some of their observation meetings. Check their site for schedules. School groups are invited to arrange scheduled visits at other times.

The observatory is located in the Duke Forest, on Cornwallis Rd, about one mile west of Kerley. Driving west on Cornwallis, access is through a Duke Forest gate on the left hand side of the road. (The gate is usually locked unless observatory is open). The gravel road through the gate forks soon. Follow the road to the right around a large shed and park in front of the shed. Turn off car headlights as soon as you have stopped! Walk down the hill to your left (away from Cornwallis) to the observatory site, about 150ft. A radio tower with a flashing red light, also to the left of the road, is just west of our site. If you get to the radio tower, you have gone too far. Click here for a map and directions.

What Can we see?:

With our telescopes, we can make out details of the Moon's surface (central peaks of craters, for example); we can see four of Jupiter's moons and clearly make out the Cassini gap in Saturn's rings; we can make out some asteroids; we can see the glowing gases of the Orion nebula or the ring nebula; we can see several galaxies and many beautiful star clusters. We cannot, for example, see the spiral structure of Andromeda. We can make out the colors of stars, especially when looking at differently-colored members of a binary pair, but for the most part objects appear too faint for our eyes to register color well.
