About this product

Model:  Trius-SX-16-Mono
Part Number:  Trius-SX-16-Mono

The Starlight Xpress Trius SX-16 offers 4,194,304 pixels of resolution. Each pixel is 7.4 x 7.4 uM in size. It features exceptionally low dark signal so no dark frames are necessary for most deep sky objects. The new 'Trius' version also adds a triple USB hub and Argon filled CCD chamber.

The Trius SX-16 is a departure from the normal SX line of Sony CCD based cameras. As Sony do not manufacture a large mono chip, we researched the available devices and decided that the Kodak KAI4022M was the best option for a new mono camera. To reduce the negative effects of the greater Kodak dark signal, we have used a two stage Peltier cooler for a 10 degree reduction in the CCD temperature, and a new high-speed USB2 interface circuit to 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. We think that the result is a highly satisfactory mono camera which overcomes the lack of suitable Sony mono devices.

MAJOR FEATURES

  • Large, high resolution Kodak CCD chip, with 4,194,304 x 7.4uM square pixels in a 15.15 x 15.15mm array.
  • Low dark signal - Dark frames not necessary for most of the brighter deep sky objects.
  • Triple output powered USB hub built-in for guider and wheel control etc.
  • Dual stage high performance cooler with -40C delta T
  • Dry Argon-filled CCD chamber for efficient cooling.
  • Anti-blooming with minimal effect on linearity and no lost active area.
  • Built-in super high speed USB 2.0 interface for approx. 2.5 second downloads.
  • High sensitivity, 55% QE at peak (green light).
  • Compact and lightweight - only 75mm in diameter x 100mm long - less than 500 grams load on the 'scope!
