Starlight Xpress has always been renowned for small, compact, innovative designs, along with excellent build quality.
The new Trius range of deep-sky, cooled CCD cameras has just taken these values to a whole new level.
In addition to the already super low-noise performance of the previous generations of SXV, SXVF, & SXVR cameras, the new Trius range is even better, whilst still offering fast download times of approximately 2 million pixels per second.
Remarkably, SX have also managed to incorporate a complete powered USB hub into the main camera, which offers 3 x USB 2.0 ports at the rear of the camera. Each port is capable of delivering up to 200mA, 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.
New Peltier cooler combinations have been designed into the Trius cameras, along with an Argon-Filled CCD chamber, allowing a greater differential cooling delta to be achieved.
The latest range of cameras from Starlight Xpress
USB hub sockets
+12v DC Power Input (+ve centre)
Fan 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 activelow 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, SX fit 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 -40C 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. SetPoint Cooling as standard.
Argon Filled CCD Chamber
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.
