TRIUS PRO-35 USB Hub CCD Camera System (Mono)
- Large, high resolution Kodak CCD chip, with 10,838,016 x 9uM square pixels in a 36.3 x 24.2mm array.
- Low dark signal – Dark frames not necessary for most of the brighter deep sky objects.
- Anti-blooming with minimal effect on linearity and no lost active area.
- Built-in super high speed USB 2.0 interface for approx. 7 second downloads.
- High sensitivity, approx. 51% QE at peak (green light), 31% at H alpha.
- Back focal distance 17mm +/-1mm.
- Built-in three port USB hub, compatible with many USB accessories (Lodestar, SX filter wheel etc)
- Single USB cable control for all features – get rid of that dangerous cable tangle!
- Only ONE computer needed to control all of the devices and functions
- Very low power consumption. Less than 1.5 amps at 12v DC – 18VA at 110v or 240v AC
- Compact and lightweight – only 118mm in diameter x 102mm long – less than 850 grams load on the telescope.
- 72 x 1mm input thread, compatible with Takahashi FSQ106 etc.
The Trius SX35 and SX36 cameras are the largest in the SX line of Truesense CCD based imagers. We have used an improved two stage Peltier cooler for efficient CCD cooling, and a high-speed USB2 interface circuit for a short 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. The camera shown on this page is the SX36, as both versions have a closely similar appearance.
