Starlight Xpress Trius SX-36 CCD Camera
TrusSense KAI-16070 35 mm Format CCD Sensor


The KAI-16070 Image Sensor is a 16-megapixel CCD in a 35 mm optical format. Based on the Kodak 7.4 micron Interline Transfer CCD Platform, the sensor provides very high smear rejection and up to 82 dB linear dynamic range through the use of a unique dual-gain amplifier. Flexible readout architecture enables use of 1, 2, or 4 outputs for full resolution readout up to 8 frames per second, while a vertical overflow drain structure suppresses image blooming and enables electronic shuttering for precise exposure control.

The Starlight Xpress SX-36 uses one of largest Kodak sensors in the Trius line, which is why the body for this camera (and the SX-35) is slightly larger than others that use sensors with smaller footprints. The fast download minimizes the visibility of bias frame artifacts, such as hot columns and the top to bottom gradient that is commonly seen on such chips.

About the SX Trius Camera Body

USB Hub with Three Ports

A complete powered USB hub is incorporated into the Trius, which offers 3 x USB 2.0 ports at the rear of the camera. Each port is capable of delivering up to 200mA, allowing you to drive a Lodestar, SuperStar or CoStar for guiding while 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.

Rear Camera Panel

The Starlight Xpress 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 or 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 dew building up on the front window during humid weather.

Efficient Cooling System

The Trius 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 heat sink (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 Chamber

The Starlight Xpress 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

The tilted camera front is a unique approach to camera design, allowing 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.

The slightly enlarged SX-36 Trius body is rugged and compact, with a diameter of 118 mm and a length of 102 mm. It is also fairly light weight (for the monster chip it has within it!) at 2.4 lb.. The back focus is approximately 17 mm (+/- 1 mm).
