The ZWO ASI664MC color camera is among the latest offerings from ZWO providing an excellent option for planetary, lunar and solar imaging.
The ZWO ASI664MC utilizes Sony’s STARVIS 2 technology which helps produce exceptional image quality through its back illuminated sensor design. The increased sensitivity to near infrared (NIR) offers heightened performance in low light for an enhanced astroimaging experience.
The 4.15MP Sony IMX664 sensor includes a small pixel size of 2.9um, a large full well capacity of 36.5Ke, and 12bit ADC for highly detailed images with excellent dynamic range. The low readout noise of 0.46e and high peak QE of 91% provides an excellent signal to noise ratio within the frames captured.
The camera offers a DDR3 memory buffer which provides an extra 256MB of internal memory which significantly reduces buffer speeds during image transfer, allowing for high-speed imaging in a smooth, seamless manner.
The onboard USB3.0 comes furnished with a large bandwidth, fully supporting the high frame rate of 95MP at full 4.15MP. The ASI664MC can be connected directly to the auto guide port of a mount through the ST4 port for guiding capabilities.
The camera incorporates an anti-reflective (AR) coated protective window which serves to improve Ultraviolet (UV) and Near-Infrared (NIR) performance, allowing the ZWO ASI664 to capture a broader spectrum of light with greater precision.
The camera also offers 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.
