The new 'Trius' version adds a triple USB hub and argon fill to the H674C design.
Features
- 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 USB hub with three ports for USB accessories.
- Two stage cooler with dry Argon filled CCD chamber.
- 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.
