Standeford Observatory

Page address:

Standeford Observatory — the smaller of the two campus observatories -- is home to a variety of telescopes. These instruments are used primarily for visual observations of the sky by MSU students and other observatory visitors. Standeford Observatory is staffed by undergraduate student observing assistants under the supervision of astronomy faculty members.

Standeford Observatory is located at the far south end of the campus, adjacent to the Ropes Course and about 150 yards west of Andreas Observatory. It can be reached by walking through the gate at the end of Lot 1 and following the gravel road south for about 400 yards.

14" Meade

Inside the 3-meter Observa-DOME is the principal telescope at Standeford Observatory -- a 14" Meade LX200 (a 14-inch Schmidt-Cassegrain). This computerized telescope stores the coordinates of over 140,000 celestial objects in its memory.

Additional Telescopes

The other telescopes at Standeford Observatory are used outside the dome, on the concrete pad. Most are Newtonians with Dobsonian mounts; all are mounted on rolling platforms for easy positioning around the pad.

The current roster of 'outside' telescopes includes the following:



Standeford Observatory is open regularly during the fall and spring observing seasons, and is used primarily by students in astronomy and related classes.

Hours and days of operation vary with the season, the weather, and demand.


Standeford Observatory SignVisitors are welcome any time the observatory is open. Students may bring friends who are not taking astronomy classes.

Visitors may call the observatory directly at (507) 389-6208 during evening hours to determine whether it is open. Additionally, a sign on the gate at the south end of Lot 1 will indicate whether Standeford Observatory is open to the public.

Public Viewing

Special public viewing events at Standeford Observatory are held occasionally during the year, sometimes in conjunction with Andreas Observatory. Targets of these special events in the past have included Comet Hale-Bopp, Comet Hyakutake, Comet Halley, lunar eclipses, solar eclipses, various planets, and the Moon. Announcements of special observing events will be made through the local news media and on these web pages.

Standeford Observatory is also open regularly to the public every Thursday evening during the fall and spring observing seasons. See Thursday Nights at Standeford Observatory for details.

Sky Conditions at Standeford Observatory


Observatory visitors are encouraged to walk from campus if possible. Those who must drive to campus may park in the south end of Lot 1 (near the Gage dormitories) and walk to the observatory.

In 1978, Dr. Leo V. Standeford — professor of astronomy at MSU from 1968 to 1981 — acquired a 3–meter Observa–DOME and placed it on the roof of Trafton Science Center. There it sheltered the small telescopes used for student observations. However, vibration of the roof made this site less than ideal for observing, resulting in the relocation of the dome to the south edge of campus.

By 1980, the observatory was a fenced enclosure containing the Observa-DOME on a concrete pad, but without any telescope inside the dome. A small metal storage shed and an experimental radio telescope — built by Dr. Standeford and his students — also shared space on the pad. Dr. Standeford was constructing a 12.5-inch Cassegrain telescope for use in the dome at the time of his death in June, 1981.

A concrete pier was poured, the new telescope was installed, and Leo V. Standeford Observatory was dedicated by President Margaret Preska on May 1, 1982.

Soon after the dedication, a windstorm destroyed the metal storage shed; but in the fall of 1983 a new shed was constructed to accommodate the observatory's additional telescopes, a collection that has increased significantly over the years.

In August 2003 after 21 years of hard use, the C11 was retired from the dome and replaced by the 14" Meade LX200. A [JPG] new base (218 KiB) was constructed for the C11, and it now serves outside the dome with the other telescopes used at the site.

In May, 2005, after 23 years of manual dome rotation, the Standeford Observa-DOME was finally motorized. Azimuthal motors were apparently not standard equipment in 1978, but the Observa-DOME folks were happy to fabricate a special bracket that mounts one of their motor-driven tires on the dome. Now the dome can be rotated by throwing a switch, making the observing assistants' job that much easier.

From 1982 to 2006, Standeford Observatory was located on the southern edge of campus about 250 yards southeast of the Gage dormitory parking lot (Lot 1).

In the summer of 2006, Standeford Observatory was relocated to a new site farther south, about 400 yards beyond the Lot 1 gate, in the woods next to the MSU Ropes Course.

Standeford Observatory Relocation Map

This location provides better screening from campus lighting, a larger observing pad and storage shed for the Standeford telescopes, and improved event coordination with Andreas Observatory, only 150 yards to the east.

Relocation of the 3-meter Observa-DOME was accomplished without a problem on July 25, 2006, thanks to a very capable construction crew.
