ZWO ASI664MC [COLOUR]

The ZWO ASI 664MC is a professional colour planetary camera containing the Sony STARVIS 2 IMX664 CMOS backlit colour sensor which has a diagonal of 1/1.8" and a resolution of 4.15 MP with 2.9µm pixels. The 664MC can be considered an iteration of the ASI 662MC, with zero amp glow, greater sensor size and higher resolution.

The sensor has a maximum QE up to 91%. This high sensitivity across the visible and near IR light spectrum and very low readout noise make it ideal for high resolution solar and planetary imaging. The ASI664MC has a large full well depth of 36.5ke- and incredibly low read noise of 0.46e-.

The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 95fps (12bit, normal mode) at full resolution (4.15 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 ASI664MC 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 252 gain and higher, HCG mode will automatically activate, giving a read noise lower than 1.0e- with a dynamic range close to 11-bit.

The ASI664MC has built-in anti-amp glow circuitry which is implemented directly at the hardware level. The camera also includes an AR-coated protective window (21mm diameter, 1.1mm thick) over the sensor, improving the performance in UV and NIR wavelengths.
