Virtual Tour

This bilingual, high-resolution tour embeds relevant information, images, and video of the Samuel Oschin Telescope. We recommend viewing the virtual tour on a desktop or laptop in fullscreen mode using the icon in the control bar. While it is possible to view the tour in smaller screens (e.g., large tablets), we suggest using the "lite" version of the tour for screens narrower than 700px (e.g, smaller tablets and smartphones). The lite tour is also VR-enabled, but lacks many of the features found in the full version of the tour. Click here to load the full tour.
