High resolution 'Exview' CCD chip, with 1,447,680 x 6.45uM pixels in a 9 x 6.7mm array.
Exceptionally low dark signal - No dark frames necessary for most deep sky objects.
Triple output powered USB hub built-in for guider and wheel control etc.
Dual stage high performance cooler with -40C delta T
Dry Argon-filled CCD chamber for efficient cooling.
Exceptionally effective anti-blooming with minimal effect on linearity and no lost active area.
Built-in very high speed USB 2.0 interface for sub-1 second downloads.
Exceptionally high QE over an extremely wide spectral range from near UV to deep IR.
Back focal length 17mm +/-1mm.
Built-in autoguider interface and output - compatible with the optional dedicated external guide camera.
Built-in dual serial ports for accessory control - directly drive filter wheels, GOTO 'scopes etc.
Single USB cable control for all features - get rid of that dangerous cable tangle!
Only ONE computer needed to control all of the devices and functions.
Very low power consumption. Less than 1.5 amps at 12v DC.
Compact and lightweight - only 75mm in diameter x 70mm long - less than 300 grams load on the 'scope
We at Starlight Xpress believe that our cameras should be as user friendly as possible. This is the philosophy behind the design of the SX TRIUS-H9 and results in a camera which needs virtually no maintenance and the minimum of effort to take top-notch astro photos. One key feature of the design is the ultra-low dark current, which means that dark frames are now totally redundant. It also means that the camera has no need of heavy cooling fins, or water cooling pipes and mess.

The autoguider and auxiliary functions:
The rear panel of the TRIUS-H9 provides multiple inputs and outputs, as shown. The three mini B USB sockets provide independent USB 2 outputs for controlling low power USB peripherals. For example, a Lodestar or SuperStar guider and an SX filter wheel may be connected via these ports. The RJ11 autoguider output is opto-isolated and will drive any standard active-low guider input via an RJ11 'telephone' lead.
