TRIUS CCD Cameras |
|
The latest range of cameras from
Starlight Xpress |
|
|
|
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, we 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.
Below are some of the innovative design features of the
new Starlight Xpress Trius cameras
|
 |
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, we fit a specially
manufactured fused silica window, with a 7 layer
anti-reflective coating, to all of our 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. Set-Point 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. |
