TRIUS PRO 834 - BLUE Edition

A new addition to the Trius camera range, the PRO-834 uses a 12 megapixel Sony CCD with 3.1uM square pixels. This very high resolution chip is well suited to short focus optics, such as the Starizona 'Hyperstar' adaptor, and many compact APO refractors. The new PRO board design has given this camera an exceptionally low readout noise figure of better than 3 electrons RMS and a fast download time of only 5 seconds in full resolution mode.

Major features:

  • Medium format, high resolution 'EXview’2 CCD chip, with 12M Pixel (3.1uM x 3.1uM square pixels) in a 15.98mm diagonal array.
  • Exceptionally low dark signal - No dark frames necessary for most deep sky objects.
  • Excellent QE of 77% peak in yellow light, 65% at Hydrogen alpha (656 nm).
  • Three port powered USB hub built-in. Can drive a Lodestar X2 or Ultrastar guider + a SX filter wheel.
  • High performance two stage cooling for better than -40C delta T
  • Dry Argon CCD chamber fill for improved cooling performance.
  • Exceptionally effective anti-blooming with minimal effect on linearity and no lost active area.
  • Back focal length 17mm +/-1mm
  • High speed USB 2.0 interface for approx. 8 second downloads.
  • Built-in triple powered USB hub for guider and filter wheel control.
  • Single USB cable control for all features - get rid of that dangerous cable tangle!
  • Very low power consumption. Less than 1.5 amps at 12v DC.
  • Compact and lightweight - only 75mm in diameter x 70mm long - Only 450g load on the telescope.
