All-sky Camera

Introducing the ASI676MC/MM , the 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.

ASI676MC / MM Highlights

Why Square Format?

One of the biggest benefits of ASI676MC/MM'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/MM more compatible with various types of lenses such as fisheye lenses and wide-angle lenses. Thus, ASI676MC/MM is more suitable for tasks such as meteor recording and full sky surveillance.

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, ASI676MC/MMexhibits lower readout noise and dark current, along with significantly enhanced sensitivity in the near-infrared spectrum.

256MB DDR3

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.

No Amp Glow

ASI676MC/MM 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.

HCG Mode

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 11 stops.

Quantum Efficiency

The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and lower readout noise are necessary to improve the image signal-to-noise ratio.

Dark Current Noise

The ASI676MC/MM'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

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.

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.

Isabella F. ★★★★★

The square sensor really makes a difference for meteor trails—I captured a full night of activity without any cropping issues. The 12MP resolution is sharp enough that I can clearly pick out faint streaks in the final stacked images, which honestly blew me away for the price.

Riley B. ★★★★★

The square sensor is a game-changer for covering more sky in each frame, and the 12MP resolution captures meteors with surprising clarity. Even faint streaks show up crisp in my initial tests.

Emily ★★★★★

The square sensor is a game-changer for meteor work—that 12MP resolution catches so much more sky detail than my old wide-angle lens setup. First clear night out and the star trails came out razor sharp, even with the moonlight washing things out a bit. Setup took me about twenty minutes and it's be
