Product information

New, updated camera from Starlight Xpress
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.

The new Trius Pro versions of the H35 and H36 Starlight Xpress cameras incorporate a triple output powered USB hub for guider and filter wheel control.

Features include regulated set-point temperature control with superior fan assisted cooling and ultra-low read noise in a compact, light-weight body.

To reduce the negative effects of the greater Kodak dark signal a two stage Peltier cooler delivers an extra 10 degree reduction in the CCD temperature and a new high-speed USB2 interface circuit greatly reduce the download time.

The fast download minimises the visibility of bias frame artefacts, such as hot columns and the top to bottom gradient that is commonly seen on such chips.

Trius SX35 Mono

  • Large, high resolution Kodak KAI-11002 CCD chip, with 4032 x 2688 9uM square pixels in a 36.3 x 24.2mm array. 
  • High sensitivity, approx. 52% QE at peak (green light), 31% at H alpha.
  • Low dark signal - Dark frames not necessary for most of the brighter deep sky objects
  • Anti-blooming with minimal effect on linearity and no lost active area
  • Built-in super high speed USB 2.0 interface for approx. 4 second downloads
  • Built-in autoguider interface and output - compatible with the optional dedicated external guide camera
  • Built-in dual serial 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!
  • Only ONE computer needed to control all of the devices and functions
  • Very low power consumption. Less than 1.0 amps at 12v DC - 12VA at 110v or 240v AC
  • Compact and lightweight - only 118mm in diameter x 112mm long - less than 1100 grams load on the telescope.
  • 72 x 1mm input thread, compatible with Takahashi FSQ106 etc.
  • CCD type: Kodak KAI11002M interline CCD with low dark current and vertical anti-blooming.
