ZWO ASI678MM Camera

The ZWO ASI678MM camera is among the latest offerings from ZWO providing an excellent mono camera option for planetary, lunar and solar imaging. It utilizes the latest Sony IMX678 sensor with 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.

ZWO ASI678MM CameraThe ZWO ASI678MM camera’s Sony IMX664 sensor offers 4K resolution, 3840 x 2160-pixel array, small pixel size of 2.0um, a large full well capacity of 11.27Ke, and 12bit ADC for highly detailed images with excellent dynamic range. The low readout noise of 0.6e and high peak QE of 83% 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 design of the camera also offers the significant advantage of zero-amp glow.

The onboard USB3.0 comes furnished with a generous 5Gb bandwidth, fully supporting the high frame rate. The camera can be connected directly to the auto guide port of a mount through the ST4 port for guiding capabilities.

The ZWO ASI678MM camera also incorporates an anti-reflective (AR) coated protective window which serves to improve Ultraviolet (UV) and Near-Infrared (NIR) performance, allowing the camera 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.
