Astrophotography Performance

ASI224MC has a 1/3″ and 1.2M pixels sensor IMX224 with SONY Exmor and NIR Technology. Extremely low read noise (1.5 e) and high sensitivity especially in IR range. Read Noise of ASI224 less than 1e which can compare with sCMOS or EMCCD sensors. Very suitable for astronomy planetary and small DSO imaging.

High QE

Relative QE Curve, we estimate the Peak Value should between 75%-80%.

PCB Version1.3 (include Anti-amp glow function)

Most sensor will have amp-glow problem only if you do long-time exposure capture, such as longer than 1s.

We apply “amp glow reduction technology” to our ASI224MC and ASI224MC-C camera, it is a hardware modification to reduce the amp-glow of the sensor, not every sensor can benefit from this modification, but it is obvious for ASI224MC, so this upgrade is for ASI224MC  and ASI224MC-C only .

We made this change since April 2016, which means the current unit (ASI224MC and ASI224MC-C) we produce all equiped with the newest PCB version —V1.3.

USB 3.0 PORT AND ST4

USB 3.0 Port: can provide 5Gb bandwidth to let ASI224 run at 64fps (12bit, normal mode) or 150 fps (10bit, high speed mode)  at full resolution(1.2Mega).

ST4 Port: can be used connect with auto guide port of mount, for guiding.
