Description
With the ability to capture light in the near-infrared portion of the spectrum, and the super high sensitivity combined with ultra-low readout noise, this camera is considered as the highly improved version of ASI290MC. It will offer great performance for planetary, solar and lunar imaging.
IMX462 sensor
The format of the IMX462 sensor is 1/2.8”. The sensor length and width are 5.6mm*3.2mm and the diagonal is 6.46mm. The resolution is 1936*1096.>
HCG mode
The cameras has a built-in HCG mode which can effectively reduce the readout noise at high gain and keep the same wide dynamic range as you would expect at low gain. When the gain is 80, the HCG mode will automatically turn on. This results in the read noise being as low as 0.47e- while the dynamic range still can reach close to 12 stops.
QE curve
ASI462 has very high QE value at 800-1000nm wavelength (almost 2 times higher than that of ASI290MC). The sensitivity in near-infrared light region ranks first among all ASI planetary cameras.
ASI462MC vs ASI290MC (see photo comparison)
In general, ASI462MC and ASI290MC share very similar characteristics but ASI462MC has some benefits in its favour in terms of lower readout noise and higher QE value.
USB 3.0 Port & ST4 Port
USB 3.0 Port: Providing 5Gb bandwidth to let ASI462 run at 136.1fps (10bit, high speed mode) or 63.9fps (12bit, normal mode) at full resolution(2.1Mega).
ST4 Port: Can be used to connect with auto guide port of mount for guiding.
