Overview

• Bayer matrix single-shot colour version of the Trius SX674 mono camera. (Color Only)
• 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.
• Back focal length 17mm +/-1mm.
• Built-in autoguider output - compatible with most mounts.
• Built-in triple USB hub ports for accessory control - directly drive filter wheels, GOTO 'scopes etc.
• Single USB cable control for all features - get rid of that dangerous cable tangle!
• Two stage cooler with dry Argon filled CCD chamber.
• 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

Description

The TRIUS range of cameras was introduced in 2014. These were the first cameras on the market to
incorporate a powered USB 2.0 hub in the rear of the camera to enable the user to connect their USB
filter wheel and guide camera directly to the camera rather than multiple cables back to the computer -
simplicity and convenience.

The new TRIUS PRO series follows on from that success. We have redesigned the electronics to give
even lower read-noise figures and faster downloads. With the Sony CCD cameras, we are now getting
read-noise figures that are better than CMOS cameras (when used at unity gain), along with 16bit data
and significantly better dark-noise figure thanks to the impressive cooling. Dark frames really are a thing
of the past, making calibration frames optional rather than compulsory, giving you more time to capture
data and process your images.
