The QHY5III462C has "Super High Conversion Gain" capability.  By using a lower capacitance, a small amount of charge can be converted to a high voltage resulting in higher sensitivity in low-light conditions. The readout noise of the QHY5III462C is as low as 0.5e-.  The following pictures demonstrate the low light improvement over the 290 sensor.  The QHY5III462C image is on the left and the QHY5III290C image on the right.  The low light conditions and exposures are identical for each image.  This image shows the QHY5III462C has higher sensitivity and SNR than the QHY5III290C in the same conditions.cameras:

The QHY5III462C comes with two free 1.25-inch filters. The IR850 filter is a long wavelength pass filter that allows wavelengths > 850nm to pass through. The UV/IR filter passes visible light and blocks the NIR. With these two filters you can capture both RGB color images and NIR monochrome images with the same camera. At NIR wavelengths, the RGB filters become transparent and the camera behaves like a monochrome IR camera.

Sony's new sHCG (Super High Conversion Gain) technology produces a higher voltage from fewer photons resulting in greater sensitivity even at very low levels of light. With sHCG technology, even in visible light, the QHY5III462C has higher sensitivity than the back-illuminated IMX290 based cameras.

The QHY5III462C pixel size and array is essentially the same as the popular QHY5III290 camera but the new QHY5III462 model offers two very significant improvements over its predecessor:  Extended NIR QE (with NIR monochrome imaging capability) and sHCG or Super High Conversion Gain.

The QHY5III462C uses Sony's latest generation IMX462 back-illuminated sensor with extended red and near infrared response. It has nearly double the red and NIR sensitivity as previous generation BSI sensors and even greater sensitivity compared to front illuminated sensors. Because the RGB filters become transparent at NIR wavelengths, the camera captures RGB color images in visible light and monochrome images in NIR.

To produce the highest detail with the greatest dynamic range, many planetary imagers prefer to capture hundreds or thousands of images in as short a time as possible and then process the results into one final combined image. This requires high sensitivity for short exposures and low read noise for combining multiple images. The QHY5III462C will output 135 frames per second at full resolution. With its exceptionally high QE and extraordinarily low (0.5e-) read noise, it is the perfect camera for planetary imaging.

The IMX462 sensor is the newest "6th Generation" sensor from Sony.  With each successive generation, Sony has made significant improvements in sensor sensitivity.  In the 6th generation of sensors, back-illuminated technology is enhanced with physically deeper photo sites allowing the capture of longer wavelength photons in the red and near infrared portion of the spectrum.  The back-illuminated structure of the pixel also allows more photons, include these longer wavelength photons, to be captures in less time.  This greatly improves the sensitivity of the pixel to near infrared in the 800 - 1000nm range which is approximately doubled when compared to cameras using the back-illuminated 290 sensor.
