TRIUS -SX694

Major features:

  •  

  • Medium format, high resolution 'Exview' CCD chip, with 6,050,000 x 4.54uM 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 or Superstar guider + 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. 5 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 - less than 500 grams load on the telescope.
