The SXV-H9 camera specification:

  • CCD type: Sony ICX285AL Exview HAD CCD with ultra low dark current, extended IR response and vertical anti-
    blooming.
  • CCD quality: Grade 1 or better - No bad columns, no dead pixels, no more than 6 'hot' pixels (saturated in <10
    seconds).
  • CCD Full resolution Pixel data: Pixel size: 6.45uM x 6.45uM, Image format: 1392 x 1040 pixels
  • CCD Image area: 8.98mm (Horizontal) x 6.7mm (Vertical).
  • Spectral Response: QE max at 540nM (~65%), 50% roll-off at 400nM and 750nM.  
  • Readout Noise: Less than 12 electrons RMS - typically ONLY 7 electrons!  
  • Full-well capacity: Greater than 27,000 e- (unbinned)
  • Anti-blooming: Overload margin greater than 800x.
  • Dark current: Dark frame saturation time greater than 100 hours. Less than 0.02 electrons/second @ + 10C ambient.
  • Data format: 16 bits.
  • System gain:  0.45 electrons per ADU
  • Computer Interface: Built-in USB 2.0 compatible interface. Also works with USB 1.1.
  • Image download time: Typically 3.5 - 4 seconds full resolution using USB 2.0, approximately 7 seconds with USB 1.1.
  • Power requirements: 115VAC / 240VAC @ 12VA, or 12VDC @ 750mA max.
  • Cooling system: Regulated constant current cooling supply with single stage thermoelectric cooler to give a CCD
    temperature of approximately -30C below ambient.
  • Size: 63 x 95mm black anodised aluminium barrel with 42mm 'T2' thread at the CCD window end & input/output plugs at
    rear.
  • Weight: approx. 350g.

SXV-H9 CCD Imager
I received a Starlight Xpress SXV-H9 camera in June 2005.  The first night out seeing was poor, but I took my first image of the
Globular Cluster, M53.
