SXVR-H814 QE Comparison of H814/H814C with H9
Truly the next revolution in Cooled CCD Cameras from Starlight Xpress.
The SXVR-H814 uses the very latest and certainly the best CCD to be released by Sony since we started designing and producing cameras around Sony CCDs in 1991. It has a remarkable Quantum Efficiency of 77% which was previously unheard of in an interline sensor; but with all of the wonderful benefits of an interline CCD, especially from Sony such as incredibly low thermal noise and very fast electronic shutter (no need for mechanical shutters).

The CCD is available in both single-shot colour and mono, so you can have the ability to capture striking colour images with a single exposure or take full advantage of the versatility of using the monochrome version for scientific applications, such as photometry and narrow band imaging etc.

Key Features of the SXVR-H814 series CCD Camera

• Exceptionally High QE • Incredibly low noise (thermal and readout) • Compact and light-weight
• Remarkably Low Power consumption • Outstanding build quality • Fast downloads

Efficient Cooling System
The cooling system is designed for the most efficient cooling possible in a compact package. The CCDs are Peltier cooled, with the extracted heat being removed by air drawn through holes in the cooler plate, and then expelled out the rear of the camera by the fan. The whole body is used as a heatsink for the heat generated during the cooling process.
Fused Silica Window
Unlike less expensive cameras, we fit a specially manufactured fused silica window, with a 7 layer antireflective coating to all of our SXVR Cameras. This offers exceptional strength and heat transfer characteristics to ensure there is less chance of dewing of the front window during humid weather.
Unique Tilted Camera Front
This unique feature of the camera design allows the front plate of the camera to be tilted to ensure that the CCD and the focal plane are parallel to each other. This enables the user to adjust for any collimation issues with the optical train to ensure pinpoint stars across the field.
To assist with the excellent cooling design of the camera housing and the unique tilted front design of the cameras, we have introduced a ‘Silver-Impregnated O-Ring’ to not only act as a light seal for the camera but also to allow heat
to conduct through the front of the camera to the rest of the optical train, helping to gently warm it, assisting to reduce the formation of condensation.
Rear Camera Panel
The SXVR Camera provides multiple inputs and outputs. The RJ11 Guider Port output is opto-isolated and will drive any standard active-low guider input via the RJ11 'telephone' lead provided. The ‘SXV Autoguider Port’ is an 18 way latching high density connector, which provides both power and control signals for the dedicated external guide camera (not supplied). It also carries two RS232 serial ports for external device control. If the serial ports are not required, the guide camera may be connected directly to this socket, otherwise a small 'port divider' box can be connected in-line and presents the two serial outputs on standard 9 pin 'D' plugs.
HyperStar Perfect
The SXVR range of cameras is perfectly suited to the HyperStar system designed by Starizona. The round and light-weight body (400g (>1lb)) is smaller than the central obstruction on even the Celestron C6 so none of the aperture of the telescope will be obscured.
