Red Buttes Observatory

at the University of Wyoming



RBO is located 9 miles south of Laramie, WY, at 105 34' 26.5" W, 41 10' 35.11" N at an elevation of 7368 feet (78 Vista Grande Way). The proximity to Laramie and relatively dark skies make RBO an excellent rapid-response telescope for imaging of transient astronomical objects such as supernovae, gamma-ray bursts, variable stars, asteroids, comets, and more. UW graduate and undergraduate students use RBO as part of their astronomical training and thesis research.

RBO is an F/8 24-inch (0.6 m) reflecting telescope designed by DFM. It was built in 1994 with a $344,000 grant from the National Science Foundation. RBO is currently equipped with an Apogee Alta U16-M 4096x4096 ccd with 9 micron pixels (0.38"/pix) yielding a ~25.9' field of view. An apogee Alta U47 1024x1024 (13 micron pixels; 0.55"/pix) ccd is also available, yielding a 9.3' FOV with ~20% higher peak QE than the U16M. The filter set includes Bessel UBVRCIC and a narrowband Halpha, Hbeta, [O III], [N II], [S II], and Green/Red/NIR continuum set in an eight-position DFM filter wheel holding 50 mm diam. filters.
