The Trius SX-674 features one of the best CCD sensors for astronomy from Sony to date. The Trius SX-674 is available in single-shot colour or mono versions for narrowband imaging with a filter wheel or quicker one-shot colour imaging. 

Get in touch for special price when purchased with an Altair Astro telescope.

Quantum Efficiency is 77% which is very high for an interline camera combined with extremely low thermal (and readout) noise, and a very fast electronic shutter (no need for mechanical shutters, therefore more reliable). Image download is very quick, and the camera is very small and compact with low power usage. 

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. CCD Image area: 8.81mm (Horizontal) x 6.63mm (Vertical)
  • Exceptionally low dark signal - No dark frames necessary for most deep sky objects. 
  • 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. 
  • Very high sensitivity - 77% QE at peak of response in yellow light, 65% at Hydrogen alpha line (656 nM). 
  • Built-in autoguider interface and output - compatible with our optional dedicated external guide cameras.
  • 3x powered USB ports for guider and filter wheel control
  • Single USB cable control for all features for less cables in use overall
  • Very low power consumption. Less than 1 amp at 12v DC. 
  • Compact and lightweight - only 75mm in diameter x 70mm long - less than 500 grams load on the telescope. 


  • CCD type: Sony ICX674ALG (mono) EXview CCD with ultra low dark current and vertical anti-blooming. CCD Full resolution pixel data: 
  • Pixel size: 4.54uM x 4.54uM, Image format: 1940 x 1460 pixels 
  • CCD Image area: 8.81mm (Horizontal) x 6.63mm (Vertical). 
  • CCD quality: Grade 1 or better - No bad columns, no dead pixels, no more than 50 'hot' pixels (saturated in <10 seconds). 
  • Spectral Response: QE max at 580nM (~77%), 50% roll-off at 360nM and 770nM. Readout Noise: Less than 7 electrons 
  • RMS - typically ONLY 5 electrons! 
  • Full-well capacity: Greater than 20,000 e- (unbinned) 
  • Anti-blooming: Overload margin greater than 800x. 
  • Dark current: Less than 0.002 electrons/second @ - 10C CCD temperature. 
  • Data format: 16 bits. 
  • System gain: 0.3 electrons per ADU 
  • Computer Interface: Built-in USB 2.0 compatible interface. 
  • Image download time: Typically 2 seconds at full resolution. 
  • Power requirements: 115VAC / 240VAC @ 12VA, or 12VDC @ 900mA max. 
  • Cooling system: Regulated set-point cooling supply with thermoelectric cooler to give a minimum CCD temperature of approximately -30C below ambient. 
  • Size: 75 x 70mm black anodised aluminium barrel with 42mm 'T2' thread at the CCD window end & input/output plugs at rear. 
  • CCD alignment screws are provided for setting the chip parallel to the focal plane. 
  • Weight: approx. 400g.
