The Trius SX-694 features what is probably the best CCD ever released by Sony for astrophotography of this size, with a Quantum Efficiency of 77% which is extremely high for an interline sensor. Combined with extremely low thermal noise and a very fast electronic shutter (no need for mechanical shutters hence greater reliability) this is one of the most senstive cameras on the market. 

Get in touch for special price when purchased with an Altair Astro telescope.
This camera is very well suited to short to medium focal length scopes such as the Altair Wave Series 80mm and 102mm Super ED triplet refractors and will perform incredibly well with these telescopes, with the small pixel size of 4.54uM enabling it to take full advantage of the razor-sharp optics at 6mb resolution. If "binned" by a factor of 2x (Mono camera only) the effective pixel size increases to 9 microns making this versatile camera quite suitable for longer focal length scopes too. Extremely low noise and heightened sensitivity in binned mode would even further enhance the suitability of this camera for longer focal length telescopes such as larger refractors or even Ritchey Chretien telescopes.
Major features:
  • Medium format, high resolution 'Exview' CCD chip, with 6,050,000 x 4.54uM square pixels in a 15.98mm diagonal array.
  • CCD Image area: 12.49mm (Horizontal) x 9.99mm (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.
  • Very high sensitivity - 77% QE at peak of response in yellow light, 65% at Hydrogen alpha line (656 nM).
  • High speed USB 2.0 interface for approx. 5 second downloads.
  • 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.
