  • Kodak KAF-16803 16.7 megapixel sensor
  • -45C cooling
  • Built-in 3-port USB hub 

The Starlight Xpress Trius SX-56 is a full frame large area format cooled CCD Camera that incorporates a Kodak KAF-16803 16.7 megapixel sensor. With slightly large pixels (9um) than its SX-46 brother (6um) the SX-56 is more suited to slightly longer focal length instruments.

Starlight Xpress have put a great deal of thought into their Trius CCD camera range, with features that are not found on other cameras. These include:

  • A high thermal conductivity (~25x better than glass), multi-coated synthetic sapphire optical window. This eliminates the need for a dedicated window heater, as heat from the camera body is conducted to the entire optical window surface, therefore preventing dewing of the window even when CCD cooling is at maximum. The optical window is easy to clean with an air blower or e.g. Baader Wonderfluid and cloth.
  • A robust and reliable, easy to service and replace, stepper motor driven roller blind shutter. This unit gives a uniform illumination of the camera sensor even at very short exposure times (~0.1 seconds)
  • To get the lowest noise possible, a high level of cooling is achieved using a three stage Peltier cooler. This allows the sensor to be cooled to better than -45C below ambient. An efficient temperature controller keeps total power consumption to less than 2 amps at 12v DC.
  • For residual bulk image elimination (a “visual memory effect” caused by trapped electrons from previous images), a built-in LED flood illuminator is employed to remove this effect.
  • The CCD sensor is housed in a compact, dry argon filled chamber, with O-ring sealing, meaning that there is no desiccant to purchase and replace regularly.

A useful feature of the Trius cameras is the built in 3 port mini-USB2.0 hub. This allows other imaging accessories, such as the Starlight Xpress filter wheel and guide camera, to be connected to, powered and controlled, from the SX-46 without additional cabling which can potentially lead to cable tangle or snagging.
Each Trius camera also features fast image download time (approximately 6.5 seconds for a full 16.7 megapixel image).
