The TRIUS Pro Cameras innovate like no other, boasting impressive cooling systems and advanced electrical designs to compete with the best cameras in its class! 

Starlight Xpress has managed to incorporate a complete powered USB hub into the main camera, which offers 3x USB 2.0 ports at the rear of the camera. Each port is capable of delivering up to 200 mA, thus able to drive a Lodestar, SuperStar or CoStar for guiding leaving another two USB ports for a USB filter wheel and one other peripheral. This integration greatly reduces the number of cable trails back to the computer and gives less potential for cables tangling around the mount during your imaging session.

Peltier cooler combinations are designed into the Trius Pro cameras, along with an Argon-Filled CCD chamber, allowing a greater differential cooling delta to be achieved.

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 1.25 Amps 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-5-pin 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 5 V DC at a maximum of 200 mA.

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 Peltier cooler configuration to give approximately -45 DegC 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 high-end cameras; the 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.
