ZWO ASI676MC: The Square Sensor for All-Sky and Planets
The ASI676MC stands out with its square sensor: the Sony IMX676 Starvis 2 delivers 3552 x 3552 pixels, totaling 12.6 megapixels. This square format is ideal for all-sky monitoring with a fisheye lens, for meteor recording, and for mosaics, where no image direction is lost.
At the same time, this is a full-fledged planetary camera: the small 2.0-micrometer pixels already sample fine details at f/8 and slower, often making a Barlow lens unnecessary. The back-illuminated sensor is completely free of amplifier glow.






From meteors to the moon
With a fisheye or wide-angle lens, the camera records the complete sky for meteors, fireballs, and time-lapses. For continuous operation, the low readout noise of 0.56 electrons counts: clean images, night after night.
On a telescope, the square field provides generous framing for high-resolution moon and planet shots.

Starvis 2 performance
The Starvis 2 generation combines high sensitivity, including in the near-infrared, with 31 frames per second at full resolution: sufficient for lucky imaging and real-time display.
Weighing 126 grams and featuring a USB 3.0 connection, the camera easily integrates into any setup, from a rooftop observatory to a travel kit.

For whom yes, for whom no
Hello how to combine all-sky monitoring, meteor hunting, or high-resolution planetary imaging in one camera.
Not If you're looking for a rectangular widefield format for deep-sky, then choose a camera with a classic sensor size.
