Leander McCormick Observatory
The 26-inch has been equipped with an Opto-Mechanics Model
10-C spectrograph with a Santa Barbara Instruments ST-8 CCD as a
detector. Both instruments were designed for use with Meade
Schmidt-Cassegrain telescopes, but we have adapted them for use with
the LMO 26-inch refractor. Information on the ST-8 CCD is
The spectrograph is professional-grade with a CCD detector. With this device, students can measure, among other things, the compositions and Doppler motions of celestial objects. "It is very rare for undergraduate students to have access to a telescope as large as the 26-inch, and even more rare to have access to one equipped with such modern instrumentation," according to Steven Majewski, who teaches both graduate and undergraduate labs. "This unique new facility greatly enhances our ability to teach astrophysics to undergraduate and graduate students and is a great complement to our already strong pedagogical emphasis at UVa."
Sample SpectraThese are just a few examples of the types of observations that can be made with our new student spectrograph. We will be incorporating its use more and more in ASTR 130 (lab for non-majors), ASTR 313 (lab for majors), and ASTR 511 (lab for graduate students) in the coming semesters.
