P48 Observer Information

P48 Telescope
The Palomar 48-inch Samuel Oschin Telescope (P48) operates exclusively in a robotic, queue-scheduled service-observing mode.
P48 Instruments
The current camera installed on the Samuel Oschin Telescope is the ZTF camera, with sixteen 6k×6k CCDs that cover 47 square degrees of sky. This camera's field of view enables a full scan of the northern visible sky every three nights. ZTF's fast readout electronics enable a survey more than an order of magnitude faster than that of PTF. The ZTF camera saw first light in November 2017.
