ZWO ASI676MC 12.6 MP CMOS Color Astronomy Camera # ASI676MC

• One of the biggest benefits of ASI676MC's square format is it makes the whole mosaic construction process much easier by eliminating the need to consider the difference between the long and wide sides of the format during mosaic stitching. Not only that, the square format also makes the ASI676MC more compatible with various types of lenses such as fisheye lenses and wide-angle lenses. Thus, ASI676MC is more suitable for tasks such as meteor recording and full sky surveillance.
• ASI676MC exhibits lower readout noise and dark current, along with significantly enhanced sensitivity in the near-infrared spectrum.
• ASI676MC does not have any amp glow, no matter how long the exposure and how high the gain value you set. Note: This technology is implemented directly at the hardware level, it does not require software control.
• The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission.
• The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain. This allows the camera to maintain the same high dynamic range as it does at low gain. When the gain is 180, the HCG mode is automatically turned on. The readout noise is as low as 0.56e, and the dynamic range can still reach a level close to 11stops.
• The QE curve and readout noise are very important parameters to measure the camera's performance. Higher OE and lower readout noise are necessary to improve the image signal-to-noise ratio.
• The ASI676MC's lower dark current noise means that the image signal-to-noise ratio is also higher, especially when photographing dark objects, it produces images with better sharpness.
• ASI676MC is equipped with an UV/IR-cut coated window in front of the sensor, with a diameter of 21mm and a thickness of 1.1mm. It effectively reduces infrared interference and improves image quality.
