ASI678MM

Monochrome Planetary Camera with High Near-Infrared Sensitivity

ASI678MM incorporates Sony's latest generation sensor IMX678 with outstanding near-infrared response. Featuring large full well capacity, high dynamic range, and low readout noise, this camera has demonstrated impeccable performance in planetary imaging, as well as solar and lunar imaging. 

Clear in Low Light

Thanks to the back-illuminated 4K CMOS image sensor, this camera has excellent sensitivity in the near-infrared spectrum. When matching with an 850nm IR-Pass filter or an 890mm methane filter, it can capture great infrared images of Jupiter and Saturn.

No Amp Glow

ASI678MC/MM does not have any amp glow, no matter how long the exposure and high the gain value you set. (Note: This technology is implemented directly at the hardware level; it does not require software control.) 

IR-Cut Coated Window

ASI676MC/MM 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. 

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 even higher dynamic range.

Featuring this technology, the ASI678MM astronomical camera exhibits lower readout noise and dark current, along with significantly enhanced sensitivity in the near-infrared spectrum. 

High Conversion Gain (HCG) Mode

The camera has a built-in High Conversion Gain (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 set to 182, the HCG mode is automatically turned on. The readout noise is as low as 0.8e, and the dynamic range can still reach a level close to 11 stops. 

Dark Current Noise

ASI676MC/MM has much lower dark current noise than ASI178, bringing it better image signal-to-noise ratios. If we compare the dark frames captured with these two cameras, it can be easily found that the frame for ASI678 has much less noise and looks much smoother.
