Starlight Xpress

The Starlight Xpress Trius SX-674C offers 2,830,000 pixels of resolution. Each pixel is 4.54 x 4.54 uM in size. It features exceptionally low dark signal so no dark frames are necessary for most deep sky objects. The new 'Trius' version also adds a triple USB hub and Argon filled CCD chamber.


  • Bayer matrix single-shot colour version of the Trius SX-674 mono camera.
  • 2/3" format, high resolution 'EXview' CCD chip, with 2,830,000 x 4.54uM square pixels in a 10.97mm diagonal array.
  • Exceptionally low dark signal - No dark frames necessary for most deep sky objects.
  • Very high sensitivity - 77% QE at peak in yellow light - 65% at H alpha (656 nm)
  • Exceptionally effective anti-blooming with minimal effect on linearity and no lost active area.
  • High speed USB 2.0 interface for approx. 2 second downloads.
  • Three port powered USB hub built-in.
  • Dry Argon filled CCD chamber.
  • Built-in autoguider output - compatible with most mounts.
  • Built-in triple USB hub 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!
  • Two stage cooler with dry Argon filled CCD chamber.
  • Very low power consumption. Less than 1.5 amps at 12v DC.
  • Compact and lightweight - only 75mm in diameter x 70mm long - less than 500 grams load on the telescope.
