Details

This is a discontinued item. We suggest the H9 version intead.

 

  • Large, high resolution Kodak CCD chip, with 8,300,000 x 5.4uM square pixels in a 17.96 x 13.52mm array.
  • Very good H-alpha sensitivity (48% QE at 656nM).
  • Low dark signal - Dark frames not necessary for most of the brighter deep sky objects.
  • Anti-blooming with minimal effect on linearity.
  • High sensitivity, 56% QE at peak (540nM - green light).
  • Fused quartz optical window for good thermal and optical performance.
  • Fast, low vibration electric shutter. Latency less than 0.05 seconds.
  • Fast, low vibration electric shutter. Latency less than 0.05 seconds.
  • Fully user adjustable chip alignment for perfect focus across the entire field.
  • Built-in super high speed USB 2.0 interface for approx. 4.5 second downloads.
  • Built-in autoguider interface and output - compatible with the optional dedicated external guide camera.
  • Built-in dual serial ports for accessory control - directly drive filter wheels, GOTO 'scopes 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 1.0 amps at 12v DC - 12VA at 110v or 240v AC.
  • Compact and lightweight - only 75mm in diameter x 70mm long - less than 500 grams load on the 'scope!

 

The SXVR-H18 is another new departure from the normal SX line of Sony CCD based cameras. Until now, it was difficult for us to manufacture a camera based on a 'full frame' CCD, as such cameras need a mechanical shutter to avoid image smearing during download. We have now designed a highly miniaturised and reliable shutter that is small enough to fit inside the CCD chamber, and so here is our first full-frame camera!

To reduce the negative effects of the greater Kodak dark signal, we have used a two stage Peltier cooler for an extra 10 degree reduction in the CCD temperature, and a multicoated fused quartz optical window for reduced dewing and better UV/IR transmission. The fast 4.5 second download time 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 with excellent sensitivity and resolution.
