The ASI678MC is the upgraded camera from the ASI178MC. Compared to the ASI178MC, the ASI687MC has lower read noise, lower dark noise and no amp glow.

No Amp Glow

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, i dose not require software control

Clear in low light

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.

HCG Mode

The 678MC 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.
