Introducing the ASI676MC, 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.
Why Square Format?
One of the biggest benefits of AS1676MC'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 AS1676MC 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.
Starvis 2 Technology
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 exhibits lower readout noise and dark current, along with significantly enhanced
sensitivity in the near-infrared spectrum.
No Amp Glow
AS1676MC does not have any amp glow, no matter
how long the exposure and how high the gain value
you set.
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.
Higher QE Lower Readout Noise
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.
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. According to our estimation, the QE peak value of ASl676MC is about 83%.
Dark Current Noise
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.
IR-Cut Coated Window
ASI676MC is equipped with an 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.
