Back-illuminated CMOS

Back-illuminated sensors have always been synonymous with high sensitivity and high quantum efficiency. Back-illuminated imaging architecture orients the metal wiring behind the photo-cathode layer, reducing the light reflection caused by passing through the wiring layer. Back-illuminated CCDs have been widely used in professional astronomical research, but the substantially high costs have kept them away from amateur astronomy. The new QHY183C back-illuminated CMOS camera not only gives the same high sensitivity as a back-illuminated CCD, but also has readout noise as low as 1 electron. It is an outstandingly good value for the money with dream performance.

Sony's Image Sensor Exmor R is the back-illuminated CMOS image sensor with improved sensitivity and noise reduction - the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation
With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor's light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens, and this has also been an important issue in the miniaturization of pixels and widening optical angle response. 
A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate. 
However, compared to conventional front-illuminated structures, back-illuminated structures commonly causes problems such as noise, dark current, defective pixels and color mixture that lead to image degradation and also cause a decrease in the signal-to-noise ratio. 
To overcome this Sony has newly developed a unique photo-diode structure and on-chip lens optimized for back-illuminated structures, that achieves a higher sensitivity and a lower random noise without light by reducing noise, dark current and defect pixels compared to the conventional front-illuminated structure. Additionally, Sony's advanced technologies such as high-precision alignment have addressed any color mixture problems.

20 Mega Pixels

Twenty mega pixels, 2.4 micrometers pixel size makes the most out of the fine detail available to your telescope. Full resolution real-time output at 15 frames per second, highly suitable for EAA (Electronically Assisted Astronomy) real-time deep space observation and lucky imaging photography. By short-time exposure and massive superpositioning (stacking), you can make use of a large telescopes' advantage of high resolution, reducing the influence of atmospheric seeing. Short-time exposures can also lower the requirement for tracking accuracy, giving a higher probability of capturing a good image without fancy guiding equipment.

Glow Suppression Function

With the elaborate and heroic effort made by QHYCCD team, the incredible innovation of CMOS glow suppression function largely diminishes the effects of amplifier glow in long exposures.
