New Planetary Camera from ZWO
ZWO ASI664MC is a remarkable new planetary CMOS camera. The 1/1.8″ Sony IMX664 sensor features a small pixel size of 2.4µm pixel and a high resolution of 2704 x 1536 (4.15Mp). In high-speed mode the frame rate reaches 95 fps, while the read-out noise remains at a low level, as low as 0.46e!
Starvis 2 Technology
If you’re not familiar with SONY STARVIS technology it offers the ZWO ASI664MC outstanding image quality and image performance.
High Transmission Speed
This camera has a USB 3.0 Interface, along with the built-in 256MB DDR# cache, ensuring high-speed, smooth, and stable data transmission.
ZWO ASI664MC vs ZWO ASI662MC
ZWO ASI664MC can be considered as an iteration of the ASI662MC. With the great improvement in sensor size and resolution, it provides a larger FOV and results in high-quality images containing more details.
Zero Amp Glow
ZWO ASI664MC adopts no-glow circuitry to avoid annoying amp glow being produced and ensure the image quality no matter how long the exposure and how high the gain value is.
(NOTE: This feature is implemented directly at the hardware level, it does not require software control.)
Low readout noise, high dynamic range
The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain and keep the dynamic range at the same level as it does at low gain. At 252 and above the HCG is automatically turned on; the dynamic range is close to 11bit; the readout noise can be lower than 1.0e.
QE noise and readout are very important parameters to measure the camera’s performance. Higher QE and lower readout noise are necessary to improve the image signal-to-noise ratio. according to our estimation, the QE peak value of the ZWO ASI664MC is about 91%
The ASI664MC adopts an AR-coated filter as a protective window (Diameter: 21mm, Thickness: 1,1mm). It improved the camera’s performance in UV and NIR wavelengths.
