Trius PRO-694 M/C

Overview

• A Bayer matrix single-shot colour version of the H694 mono camera (Color Only).
• 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 -45C 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. 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.

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.
