ZWO ASI676MM Standout Features


Why Choose the ASI676MM?
All-Sky Camera!


Utilizing an ultra-wide fisheye lens, you can capture the entire night sky in a single frame, horizon to horizon. Making it perfect for monitoring meteors, aurora, cloud coverage and sky conditions in real time. The ASI676 MM is versatile enough for traditional astrophotography and even safe solar imaging when paired with the proper solar filters!
See What the Eye Can’t!


STARVIS sensor technology was developed by Sony and far surpasses the sensitivity of the human eye. STARVIS 2 is an advancement, supporting an even higher dynamic range! Exhibiting lower readout noise and dark current, along with enhanced sensitivity in the near-infrared spectrum.
Why Square Format?


The biggest benefit of the ASI676MM is the square format sensor with a large 12MP resolution! Square sensors make mosaic constructions much easier by removing the need to consider differences between all sides of the sensor. They also allow for various compatibility such as fisheye lenses and wide-angle lenses.


Zero Amp Glow
The ASI676MM is engineered to deliver a perfectly clean image, completely free of amp glow, no matter how long your exposure runs or how high you push the gain. This isn’t a software trick or post-processing workaround; the amp-glow free performance is built directly into the camera’s hardware, ensuring consistently pristine frames and worry-free imaging even during the most demanding low-light sessions!


Buffer for Smooth, Reliable Imaging
With a high-speed USB 3.0 interface and a built-in 256MB DDR3 buffer, the camera delivers fast, stable, and reliable data transfer even during long exposures or high-frame-rate captures. This onboard memory helps prevent dropped frames and ensures your imaging workflow stays smooth and uninterrupted, no matter how demanding the session gets.


Clean Images at Any Gain in HGC Mode
The camera features an automatic HCG (High Conversion Gain) mode that kicks in at gain 180, reducing readout noise while keeping dynamic range high. Even at strong gain settings, the read noise drops to just 0.56e and the camera still delivers nearly 11 stops of dynamic range, giving you clean, detailed images without sacrificing performance.


Quantum Efficiency
Quantum efficiency (QE) and readout noise are key measures of a camera’s performance. With an impressive QE of 83% and ultra-low readout noise, this camera delivers a significantly improved signal-to-noise ratio, producing brighter, cleaner, and more detailed images.


Dark Current Noise
The ASI676MM'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.


Coated Window
The ASI676MM camera features an AR-coated protective filter in front of the sensor, with a diameter of 21 mm and a thickness of 1.1 mm. It protects the sensor from external damage while enhancing light transmission from the near-ultraviolet to the near-infrared spectrum.
