Major features:

  • Large, high resolution Truesense CCD chip, with 16,085,120 x 7.4uM 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. 10 second downloads.
  • High sensitivity, approx. 52% QE at peak (green light), 31% at H alpha.
  • Back focal distance 17mm +/-1mm.

Response

 

  • Built-in 3 port powered USB hub.
  • 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 1.0 amps at 12v DC - 12VA 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 SX-36 camera is one of the largest in the SX line of Truesense CCD based imagers. We have used a 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.
