The ZWO ASI678MC camera is a camera which adopts Sony’s latest generation sensor IMX678 with excellent near infrared response. With the advantages of large full well capacity, high dynamic range and low readout noise, this color camera has been tested and found to have perfect performance in planetary imaging, solar and lunar imaging.
Thanks to the back-illuminated sensor structure and advanced pixel technology, the camera has very low readout noise and has an ultra-high sensitivity. Especially in low light conditions, the camera performs very well and is able to capture very clear images of celestial objects.
The ZWO ASI678MC camera can be considered as an upgrade of the ZWO ASI178MC. It adopts the latest SONY IMX678 sensor with advanced STARVIS 2 technology. Compared to the ASI178MC, this camera features lower readout noise and higher sensitivity. The dark current noise is greatly decreased and the performance of near infrared is greatly improved. The ASI678MC exhibits zero amp glow, no matter how long the exposure and how high the gain value. Since it is implemented directly at the hardware level, it does not require software control.
The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain. This allows the camera to maintain the same high dynamic range as it does at low gain. When the gain is 80, the HCG mode is automatically turned on. The readout noise is as low as 1.0e, and the dynamic range can still reach a level close to 12bit.
The ZWO ASI678MC camera has much lower dark current noises than the ASI178, it has better image signal-to-noise ratios. If we compare the dark frames captured with these two cameras, it can be easily found that the frame from ASI678 has much less noise and looks much smoother.
