The ZWO ASI 385MC is a colour planetary camera containing the Sony IMX385 CMOS industrial colour sensor which has a diagonal of 1/1.9" and a resolution of 2.12 MPx. The sensor has 3.75µm pixels and good near-IR sensitivity.

 

 

The sensor has a maximum QE up to 80% at 530nm. This high sensitivity across the visible light spectrum, low readout noise and high frame rate of 120fps make it ideal for planetary and solar imaging.

The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 57.5fps (12bit, normal mode) or 82.5fps (10bit, high speed mode) at full resolution (8.2 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 ASI385MC 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 60 gain and higher, HCG mode will automatically activate, giving a read noise as low as 0.7e-.

Sony is introducing SNR1s [lx] as an index used to quantitatively evaluate picture quality at low illumination. SNR1s [lx] is an acronym consisting of “SNR” (Signal-to-Noise Ratio), “1” (represents that the signal level when noise = 1 is 1), and “s” (for Security). The lower this value is, the greater the image quality will be at low illumination. The ASI385MC has an extremely low SNR1s value of 0.13lx.
