ZWO ASI 533MC PRO [COLOUR]
The ZWO ASI 533MC PRO is a cooled camera with great performance for a very competitive price.
The ZWO ASI 553MC contains the Sony IMX533 CMOS colour sensor which has a diagonal of 15.99mm and a resolution of 9 MPx. The Sony back-illuminated sensor technology improves sensitivity and reduces the noise for the best performance.
The ZWO PRO cameras incorporate a 256MB DDR3 memory buffer that improves data transfer reliability and it minimizes amp-glow caused by slow data transfer speeds.
A higher QE means more of the light is converted into signal. The ASI 533MC has a maximum QE of 80%.
The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 20fps at full resolution.
The USB 2.0 Hub allows to connect 2 USB controlled accessories such as a filter wheel, a guiding camera or an electronic focuser, reducing the amount of cables that run directly from your computer.
The thermo electric cooling system allows a ΔT of 40°CC below ambient. The cooling system requires an external power supply of 12V at 3-5A with a 2.1×5.5mm connector (positive tip). The ASI 533MC can be powered with a standard lead battery or a DC source between 9-15V.
The dark current of the ASI533MC is extremely low, based on our test results.
Traditional CMOS sensors emit a weak infrared light and quite often it is seen in the corner of uncalibrated images. This is called "amp glow". The ASI533MC PRO uses a zero amp glow circuitry which eliminates the problem, even when using high gain and a long exposure.
With amp glow – exposure of 300 seconds:
