More information

  • Whether you are stepping into astrophotography for the first time or seeking to upgrade your existing camera, the ZWO ASI533MM Pro monochrome camera provides the performance and reliability you need to capture the deep sky in all its glory.

    Disclaimer

    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.

    Sensor Design

    The ASI533MM 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.

    Cooling System

    ZWO ASI TEC cooling

    Integrated with a powerful two-stage TEC cooling system, the ASI533MM 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.

    Versatile Connectivity

    The camera includes many ports for convenient connection of additional equipment like a filter wheel, a guide camera or a motorized focuser.

    • 1x USB3.0 for high speed data transfer
    • 2x USB2.0 ports for additional equipment
    • 1x 12V 2.1 x 5.5mm power port to power the camera

    Low Dark Current

    The ASI533MM 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.

    Quantum Efficiency

    Based on the calculations, the peak quantum efficiency of the ASI533MM Pro is greater than 91%

    ZWO ASI533MM-P Quantum Efficiency

    Low Read Noise, High Dynamic Range

    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.
