The most significant parameter of any camera is its resolution. In the case of the QHY600, the resolution amounts to 61.17mp with an effective pixel area of 9576x6388. In the case of astrophotography which is obviously low lighting conditions, high end resolution is a major component that will determine how well objects that are both wide in their angular size and/or low surface brightness are able to display their detail in each frame.

The latest Sony sensor comes equipped with an native 16-bit A/D (Analog-to-Digital) capability, enabling it to produce output with true 16 bit depth and a total of 65,536 levels. This represents a significant advancement compared to sensors using 12-bit or 14-bit A/D converters, furthermore making them the preferred choice for scientific applications where subtle details and measurements need to be obtained and suberb sample resolution.

Mainly exclusive the 16bit AD sensors, the system gain is less than 1 electron per A/D (e-/ADU) resulting in a more linear and clean quantum efficiency rate to digital value data. This results in less error and read noise, thus creating a higher signal to noise ratio, a major plus for scientific research.

Due to poorly made sensor circuitry, amp glow can occur as an affect caused by excess heat in certain parts of the sensor. This can particularly be a problem in longer exposures making post processing more difficult. The QHY600 Pro camera is zero amp glow!

The QHY600 Pro I Scientific Camera is equipped with dual stage TEC cooling to ensure the sensor reaches and maintains ambient temperature to reduce risk of excess noise appearing in frames.

As is typical in more mainstream DSLR cameras, the RAW image output is not entirely unprocessed and may still show some indications of noise reduction and hot pixel removal. While this may seem like a benefit at first, the problem that can arouse is legitimate stars being removed and mistaken for hot pixels. In the case of the QHY600, only True Raw Image Output is generated from the original signal, and also subsequents edits will happen post processing.

Any lack of photon capture will result in data not being processed by the sensor, thus not showing up in the frames. To minimize this circumstance, back illuminated sensors also abbreviated as BSI, remove the obstruction typically above the photosensitive layer of the sensor of the wiring and reverses the placement. As a result, the percentage of photons that get captured, charged and processed through the data transfer increases providing a more true detailed image frame.

The ratio of photons vs electrons produced through charge is often referred to as Quantum Efficiency. Aside from resolution, this represents probably the second most important benchmark for any sensors since it indicates how much "bang for the buck" a sensor will generate relative to light capture. In return, this ratio will determine how well dimmer objects can be captured. In the case of deep sky observation, this is especially paramount.
