About this product
Model: Trius-PRO-674-Mono
Part Number: 100-0053
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 Blue Edition 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.
The Starlight Xpress Trius SX-674 offers 2,830,000 pixels of resolution. Each pixel is 4.54 x 4.54 uM in size. It features exceptionally low dark signal so no dark frames are necessary for most deep sky objects. The new 'Trius' version also adds a triple USB hub and Argon filled CCD chamber.
MAJOR 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. 1.2 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.
