ZWO ASI676MM USB3.0 Mono Astronomy Camera - ASI676MM

The ZWO ASI676MM is an all-sky camera featuring a unique square 1/1.6-inch image sensor and a super high resolution of 12MP! It is perfectly suited for meteor recording and full sky surveillance. The square format facilitates easier composition, making mosaic stitch simpler and more efficient, and the high resolution brings you clear details of the Sun and our Moon. With this camera, you may start your marvelous journey to explore the boundless night sky.

Why Square Format?

One of the biggest benefits of ASI676MM'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 ASI676MM more compatible with various types of lenses such as fisheye lenses and wide-angle lenses. Thus, ASI676MM is more suitable for tasks such as meteor recording and full sky surveillance.

Sony STARVIS 2

STARVIS is a sensor technology developed by Sony that surpasses the sensitivity of the human eye. STARVIS 2 is an advancement of STARVIS technology, supporting an even higher dynamic range.  With this technology, ASI676MM exhibits lower readout noise and dark current, along with significantly enhanced sensitivity in the near-infrared spectrum.

No Amp Glow!

ASI676MM 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.

More Highlights of the ZWO ASI676MM...

• 256MB DDR3 - The built-in 256MB DDR3 cache and USB 3.0 transmission interface ensures stable and secure data transmission.

• HCG Mode - The ASI676MM reduces readout noise at high gain with a built-in HCG mode, allowing the camera to maintain the same high dynamic range as it does at low gain.  When gain is 180 the HCG mode automatically turns on.  When the readout noise is as low as 0.56e the dynamic range can still reach a level close to 11 stops.

• Quantum Peak - 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.

• Dark Current Noise - Lower dark current (and better signal-to-noise ratio) produces images with better sharpness, especially when photographing dark objects.

• AR 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.
