SITH

Our Space Imaging and Tracking Hardware (SITH) telescope is a 0.6 m (f/6.5) PlaneWave Corrected Dall-Kirkham (CDK24) installed on a PlaneWave L-600 mount. SITH is primarily used for detection, tracking, and characterization of dimmer objects. These include geosynchronous (GEO), cislunar, and interplanetary objects, both artificial and natural. SITH is equipped with a derotator to facilitate deep-sky sidereal tracking as well as a 10-slot filter wheel for multi-band and polarimetric characterization.Ìý
Panopticon

Panopticon consists of four 0.2 m (f/3) Officina Stellare RH200 astrographs. Each optical tube has a 10-slot filter wheel. The optical tubes are currently co-aligned for simultaneous measurements with different sensor types. The four optical tubes can also be pointed off-boresight yielding a 7 x 7 degree system field of view (FOV) with our Kepler KL4040 sCMOS cameras.Ìý
The current Panopticon configuration consists of two Kepler KL4040 sCMOS cameras, a Princeton Instruments NIRvana 640 near-infrared camera, and a Prophesee EVK3 event camera.Ìý

Kepler KL4040 sCMOS

Our primary sensors are Finger Lakes Instruments (FLI) Kepler KL4040 cooled sCMOS cameras (4096 x 4096 array, 9 micron pixels). The KL4040 has a 0.5 x 0.5 degree FOV on SITH and 3.5 x 3.5 degree FOV on the RH200.Ìý

NIRvana 640Ìý

We also use a Teledyne/Princeton Instruments NIRvana 640 near-infrared camera, sensitive from 900 - 1700 nm (640 x 512, 20 micron pixels). This yields a 1.2 x 1 degree FOV on the RH200. This sensor enables multi-band characterization and daytime detection of space objects.Ìý
Prophesee EVK3 Gen4.1 Event Camera

We also use a Prophesee EVK3 Gen4.1 event camera (1280 x 720, 4.86 micron pixels) that detects relative changes in brightness at the pixel level. This sensor outputs a stream of brightness change events rather than fixed frames. This architecture enables rapid, dynamic response to brightness change with equivalent framerates >1 kHz for high pixel brightness. The EVK3 Gen4.1 FOV on the RH200 is 0.58 x 0.33 degrees.Ìý
FLI CL-1-10 Filter Wheel

Each optical tube is equipped with a 10-slot FLI filter wheel consisting of two overlapping, 5-slot wheels. This allows for 8 independent slots plus multi-filter configurations. Ìý
The filter wheels are equipped with Sloan UGRIZ color filters, polarizing filters, and diffraction gratings.Ìý
These various configurations enable simultaneous multi-phenomenology space object characterization using the co-aligned Panopticon optical tubes.Ìý
