Starlight Xpress Trius Pro-674 USB Hub CCD Monochrome Camera w/ SXMFW-1T Mini Filter Wheel and Lodestar X2 Autoguider
- Rear Camera Panel - The TRIUS-PRO 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 1.5 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 'telescope' lead provided. The remaining sockets are three Mini-B 5pin USB2.0 sockets that can be used to control 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 fit a specially manufactured fused silica window, with a 7 layer anti-reflective coating, to all TRIUS-PRO 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-PRO cameras are fitted with a new peltier cooler configuration to give approximately -45°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, to help keep the external body at the ambient temperature during the warmer weather.
- Unique Tilted Camera Front - This unique feature of the 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. The enables the user to adjust for any collimation issues throughout the whole optical train, to ensure pinpoint stars across the entire field.
- Argon Filled CCD Chamber - Argon filled CCD chambers are normally only associated with really high-end 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 greater delta T to be achieved.

Trius Pro CCD Camera Design The Trius Pro's electronics design provides even lower read-noise figures that are better than CMOS cameras (when used at unity gain). This Trius Pro-674 has With 16bit data, an impressive cooling system, and virtually makes dark frames a thing of the past. No longer are calibration frames compulsory, they are optional! This gives astrophotographers more time to capture those impressive night sky images through data capture and image processing.
Built-in USB Hub The Trius Pro Cameras are building on the success of the previous Trius cameras. These cameras are designed with a built-in USB 2.0 Hub that allows for fewer cables to be connected to the computer. With this hub, the filter wheel and the guide camera can be connected directly to the CCD Trius camera, allowing for less clutter.
About the Starlight Xpress Mini Filter Wheel
with Five 1.25" Positions and Integrated Slimline OAG The Starlight Xpress Mini Filter Wheel, with its integrated off-axis guide prism, is a compact solution for mobile setups, or where the lightest possible wheel and guider are required. The Mini Filter Wheel is USB controlled and powered, with five 1.25” filter positions. The integrated OAG is pre-set to be close to par-focal with most Starlight Xpress cameras. The Lodestar X2 is an ideal match to the OAG pick-off tube. Connections are T-thread male and T-thread female.
About the Starlight Xpress Lodestar X2 Autoguider The Starlight Xpress Lodestar X2 is a very compact guider which is powered and operated via a single USB2.0 computer connection. The Lodestar X2 also provides an opto-isolated output connection for direct control of most mounts via their Autoguider sockets. This output is compatible with the ST4 style of RJ12 connection and supplies 4 pull down direction lines and a common return. Alternatively, you may send the mount control signals via a serial connection from the guider control computer.
The SX Lodestar X2 utilizes a very sensitive Sony ‘ExView’ CCD (the ICX829) with an array of 752 x 582 pixels in a ‘half-inch’ format. Although the chip is not cooled, it has a very low dark signal and very little readout noise, so it can be used to guide on faint stars that are beyond the reach of webcams and CMOS chip based guide cameras. Because of the high sensitivity and high dynamic range characteristics of the Sony ICX829, the Starlight Xpress Lodestar X2 makes a superb electronic finder and planetary imaging camera as well as a splendid autoguider!
Starlight Xpress products have always been renowned for a compact, innovative, and excellent build quality. The new TRIUS-PRO range of cameras has just taken this to a whole new level.
While further improving on the super low-noise performance of the previous generations of SXV, SXVF, SXVR and the original TRIUS cameras, the new TRIUS-PRO also offers faster download times of approximately 2.8 million pixels per second.
Remarkably, Starlight Xpress has managed to incorporate a complete powered USB hub into the main camera, which presents 3 USB 2.0 ports at the rear of the camera. Each port is capable of delivering up to 200mA, and is able to drive a Lodestar, or UltraStar, and a USB filter wheel, along with a third device, such as a USB focuser. This integration greatly reduces the number of cable trails back to the computer and gives less potential for cable tangling around the mount during your imaging session.
New 3 stage Peltier cooler stacks have been designed into the TRIUS-PRO cameras. Along with the Argon-Filled CCD chamber, this allows a greater differential cooling delta to be achieved.
