Whether you are stepping into astrophotography for the first time or seeking to upgrade your existing camera, the ZWO ASI533MC Pro provides the performance and reliability you need to capture the deep sky in all its glory.
All ASI cooled cameras require an external power source. We advise using a 12V 3~5A DC adapter (2.1 x 5.5mm, center positive), an 11V-14V lithium battery, or the ASIAIR for powering the camera. Please note that utilizing a power supply outside of this specified voltage range can cause irreversible damage to the camera.
The ASI533MC Pro uses a 1 inch square backside illuminated CMOS sensor with 9 megapixels at a pixel size of 3.76μm. Its square design provides a large field of view with symmetrical composition that enhances the aesthetic appeal of your astrophotographies.
This camera offers high quantum efficiency to capture great details even in low light conditions, making it ideal for deep sky imaging.
Integrated with a powerful two-stage TEC cooling system, the ASI533MC Pro can reduce the CMOS sensor temperature by up to 35°C below ambient, significantly reducing the dark current. Thereby, the improvement in signal to noise ratio (SNR) will result in clearer, sharper images of the deep sky, even with long exposures of hundreds of seconds.
The camera includes many ports for convenient connection of additional equipment like a filter wheel, a guide camera or a motorized focuser.
The ASI533MC Pro, already featuring a low dark current, demonstrates even further reduced dark current when cooling is utilized. Check the diagram below to view the significant reductions achieved with the cooling system.
Based on the calculations, the peak quantum efficiency of the ASI533MC Pro is greater than 80%
Setting the gain value to 100 activates the HCG high gain mode. This adjustment significantly lowers the readout noise without fundamentally altering the dynamic range, making this gain value the most used amongst the astrophotographers.
