For sale Starlight Xpress Trius SX-825 mono CCD camera with case/leads. Features......
Rear Camera Panel: The Trius camera provides multiple inputs and outputs. The main control connections to the camera are the USB2.0 socket that controls the camera from the computer and the +12v DC jack socket which provides power (approximately 1.25Amps at 12v DC). In addition, there is an RJ11 Guider Port output that is opto-isolated and will drive any standard active low guider input via the RJ11 telephone lead provided. The remaining sockets are three Mini-5pin USB2.0 sockets that can be used to power up to three different USB devices, such as a Lodestar Autoguider, an SX USB Filter Wheel and a focuser. Each USB port is capable of providing 5v DC at a maximum of 200mA.
Fused Silica Window: Unlike less expensive cameras, Starlight Xpress fits a specially manufactured fused silica window, with a 7 layer anti-reflective coating, to all of their Trius cameras. This offers exceptional strength and heat transfer characteristics to ensure there is less chance of dewing of the front window during humid weather.
Efficient Cooling System: The cooling system is designed for the most efficient cooling possible in a small compact package. The Trius cameras are fitted with a new peltier cooler configuration to give approximately -40 Deg.C delta T. A built in fan at the rear of the camera draws air in through small holes in the front of the barrel (which increases the surface area to aid the convection), through the heatsink where all the heat is generated, and expels it out of the rear of the camera. An additional fan is fitted to the side, just to help keep the external body at the ambient temperature during warmer weather. Set-Point Cooling as standard.
Argon Filled CCD Filter: Argon filled CCD chambers are normally only associated with really highend cameras; the new Trius cameras have dry argon injected into the CCD chamber to ensure there is no moisture to condense on the CCD during the cooling process. The low thermal conductivity of argon also helps with the cooling process, allowing a lower delta T to be achieved.
Unique Tilted Camera Front: This unique approach to camera design allows the front plate of the camera to be orthogonally aligned to ensure that the CCD and the optics are parallel to each other. This enables the user to adjust for any collimation issues throughout the whole optical train, to ensure pinpoint stars across the entire field.
CCD Type: Sony ICX825ALA (mono) EXview CCD
Pixel Size: 6.45uM x 6.45uM
Image Format: 1472 x 1050 pixels
CCD Diagonal: 11 mm
Max QE: 77%
Readout Noise: Less than 7 electrons RMS - typically only 5 electrons.
Data format: 16 bits
Computer Interface: Built-in USB 2.0 compatible interface with 3 port USB 2 hub for peripheral devices.
Image download time: Typically 2 seconds at full resolution using USB 2.0
Power requirements: 115VAC / 240VAC @ 12VA, or 12VDC @ 900mA max.
Cooling system: Regulated set-point cooling supply with two stage thermoelectric cooler to give a CCD temperature of better than -30C below ambient.
Size: 75 x 70mm black anodized aluminum barrel with 42mm 'T2' thread at the CCD window end & input/output plugs at rear.
Weight: approx. 400g.
Price $700 plus post
