Major features: A Bayer matrix single-shot colour version of the H694 mono camera. Medium format, high resolution 'Exview' CCD chip with 6,050,000 x 4.54uM square pixels in a 15.98 mm 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.
