Sierra Remote Observatories
Since founding Sierra Remote Observatories (SRO) in 2007, we have been striving to make it a premiere destination for automated astronomical imaging. After an exhaustive search, we chose our site for its exceptional seeing, darkness, weather, and convenience. The eight smaller 10' x 12' roll-off roof observatories were constructed first. They quickly became occupied, so we built our first multi-pier observatories with roll-off roofs. These observatories are currently filled with larger telescopes from professional astronomers and amateur imagers from around the world. Now, we are working on our next two multi-pier observatories, which we expect will be available in late Spring or early Summer of 2019. You can follow our progress under Site/New Construction.  We hope to apply all that we have learned over the years to make these new observatories more sophisticated and designed to accommodate even larger telescopes. To our existing clients, we are grateful for your trust. For our new clients we extend to you a warm welcome to SRO.
All the best,
​Keith Quattrocchi and Mel Helm
