The ZWO ASI 678MC is a professional colour planetary camera containing the Sony STARVIS 2 IMX678 CMOS backlit colour sensor which has a diagonal of 1/1.8" and a resolution of 8.29 MP with 2.0µm pixels. The 678MC can be considered a successor to the ASI 178MC, with zero amp glow, lower dark current noise and lower read noise.

 

 

The sensor has a maximum QE up to 83%. This high sensitivity across the visible and near IR light spectrum and very low readout noise make it ideal for high resolution planetary imaging.  


 

The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 47.5fps (12bit, normal mode) at full resolution (8.29 Megapixels). Frame rate can be limited by the power of the computer and the writing speed of your hard disk. For higher performance it is suggested to use Solid State Drives. 

The ASI678MC has a HCG mode which effectively reduces readout noise at high gain settings while preserving the same wide dynamic range that you would get at low gain. From 80 gain and higher, HCG mode will automatically activate, giving a read noise as low as 1.0e- with a dynamic range of 12 stops.


 

The ASI678MC has built-in anti-amp glow circuitry which is implemented directly at the hardware level.
