Winer Observatory

Winer Observatory is an astronomical observatory near Sonoita, Arizona in the United States. It is a private, non-profit observatory, operated by Mark and Pat Trueblood since 1983. It has been the site of a number of significant small telescopes and famous robotic telescopes, including the Iowa Robotic Observatory, Michael Schwartz's supernova survey telescope (until Tenagra Observatories opened a facility in the area), and the Kilodegree Extremely Little Telescope that discovered over 30 exoplanets. It now houses the Iowa telescope, a telescope owned by a university in Poland, and the Sutter Survey telescope owned by asteroid mining company TransAstra.
