Jefferson College Observatory - A Unique Educational Partnership

Jefferson College and the St. Louis Astronomical Society (SLAS) are working together to develop an astronomical observatory in phases near the Softball Field on the College’s Hillsboro campus. The observatory’s purpose is to engage the community to learn more about the science of astronomy and physics. It will become the first public observatory in Jefferson County affiliated with SLAS.

Regular stargazing and solar viewing events for the public will be hosted by Jefferson College and SLAS. A variety of events such as eclipses, transits, comets, and meteor showers are expected to draw large audiences. Educators and students of K-12 schools will be encouraged to make use of the observatory for educational projects. 

When complete, the observatory site will feature several buildings equipped with ready-to-use telescopes of sufficient aperture (light gathering ability) to allow for college level research and community educational events. A patio viewing area will be available to amateur astronomers and enthusiasts to explore the night sky and our closest star, the Sun. 

Members of the St. Louis Astronomical Society will also use the observatory to host public and private events.    

Observatory Facilities

The Jefferson College Observatory will be developed in phases over several years as funding is secured.

Long-term plans include three observatory buildings to house permanently mounted telescopes and provide storage for portable astronomy equipment, a patio viewing area with electrical hookups for the public and amateur astronomers to bring their own telescopes, and a wall to protect the viewing area from vehicle headlights of those that are visiting the site. The location makes use of paved parking that already exists next to the site. Restrooms are available within a short walking distance.

Structure #1 is an “observatory dome” owned by SLAS that will house a permanently mounted 16-inch telescope with a motorized dome.

Structures #2 is a patio with telescope “pads” for the public and amateur astronomers to use their personal equipment. Each pad will have electrical hookup to facilitate equipment set up.  

Structure #3 is a wall designed to shield vehicle headlights.

Structures #4 and #5 are buildings large enough to house telescopes ranging up to 30” in aperture and host 10-15 visitors at a time, while providing storage for portable astronomy equipment and accessories. Telescopes will be permanently mounted in each building, with motorized, “roll-off” roofs to simplify operation and reduce wear/tear of equipment. 

For security reasons, Jefferson College and SLAS personnel who are trained and authorized to use the equipment will coordinate use of structures #1, #4 and #5. 


Location

The observatory will be located north of the Jefferson College Hillsboro campus (on Farm Road) near the Softball Field and share a paved parking lot. The site will be especially attractive to astronomers from across the region due to its location outside the immediate St. Louis area and the associated light band.

Directions: From St. Louis, travel South on Highway 21 to the Jefferson College/Hayden Road exit. Turn right onto Hayden Road and then left onto Jefferson College Drive. Farm Road will be approximately one-quarter mile on the right.

The convenient location of the observatory site at Jefferson College is expected to draw visitors from Jefferson County and the surrounding region. Visitors from the St. Louis metropolitan area will find the observatory just a 30-minute drive on southbound Highway 21 from the intersection of Interstate 270 in St. Louis County.

Funding – Timing – Construction Phasing

Jefferson College and the St. Louis Astronomical Society will partner to raise funds to develop the site. Observatory project funds will be raised from public donations, grants, and corporate sponsors. Project rollout will be determined by available funding for each phase. Each phase of the project will be functional on its own, making the observatory useful from the outset. Estimated costs of each phase will not be available until architectural drawings are complete.  

Development of the observatory site is planned to proceed in the order shown on the architectural rendering design above: Structure #1 (observatory dome), followed by structure #2 (viewing patio), followed by structure #3 (headlight shield wall), followed by structures #4 and #5 (buildings with retractable roofs). 

An initial amount of $38,000 in Capital Project Funds has been approved by Jefferson College and will be allocated according to the following priority order illustrated on the site plan:

  1. Construct platform for the SLAS-owned dome and telescope
  2. If funding remains, construct concrete patio for individual telescope set up/viewing
  3. If funding remains, construct headlight shield wall


The St. Louis Astronomical Society has purchased adequate equipment and accessories to be placed in the observatory buildings being developed. 

 

Support the Observatory Project – Donate Today

Although the Jefferson College Observatory will be FREE to all visitors, donations of all amounts are needed to enable construction and site maintenance. Anyone interested in supporting the Observatory can make a tax-deductible donation through the Jefferson College Foundation, a separately incorporated 501 (c)(3) nonprofit organization, whose purpose is to increase resources, raise funds, and cultivate friends and partnerships to support Jefferson College and its mission.There are a variety of ways you can make an impact with a donation of any amount.

Contribute $10 and Receive a Genuine Meteorite

Ever wanted to own a piece of space…something out of this world? For an individual donation of only $10, you will receive a genuine commemorative meteorite as a thank you. Your Northwest Africa meteorite will come in a 1-1/8 inch acrylic case with a description of the origin. Each meteorite is unique and will vary in size, with most being less than 1/4 inch in size. Meteorites will be available for pick up at the Jefferson College Foundation Office, located in the Administration Building on the Hillsboro campus, after October 1.
