Medium format, high resolution ‘Exview’ CCD chip, with 6,050,000 x 4.54uM square pixels in a 15.98mm diagonal array.

Description

Trius PRO-694 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 PRO or Ultrastar PRO + 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 16mm +/-1mm.

• High speed USB 2.0 interface for approx. 2.5 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.
