The Chinese company ZWO (Zhen Wang Optical) offers a range of astronomical cameras with amazing quality, performance and price The ASI533MM model is equipped with a 1-inch, 9-megapixel monochrome sensor (3008 x 3008 pixels), which This makes it ideal for deep sky imaging Cooling below ambient temperature (35 °C) is achieved by means of a Peltier module and a silent fan, which significantly reduces thermal noise.

In terms of sensitivity, the ASI533 stands out for its high-performance Sony IMX533 CMOS sensor, capable of achieving a maximum sensitivity of 91% thanks to Exmor R back-illuminated technology. This maximum sensitivity approaches 60% in the Hydrogen Alpha line (at 656 nm, the emission range of many nebulae). Its low read noise and lack of pre-amplification are also noteworthy. In the "Pro" version, This camera has a 256 MB buffer, which significantly increases the sensor's reading speed.

In planetary imaging, it reaches a resolution of 3008 x 3008 pixels at 20 frames per second and a 14-bit color depth. The acquisition speed reaches 216 frames per second at a resolution of 320 x 240 pixels at 14 bits. The ASI1533MM-Pro features an M42 female input thread. Several cables and adapters are included for various configurations (see the "Documentation" section).

Software

As with all ZWO cameras, The main and most complete control software is ASIStudio which can be downloaded for free from the ZWO website . ZWO also offers a free SDK (Software Development Kit), which allows many programs, both free and paid, to be natively compatible with ZWO cameras: Prism, NINA, FireCapture, MaximDL, SharpCap, PHD2, AllSkEye, and others. We recommend consulting the specific documentation for these programs to determine their compatibility or visiting the ZWO website for a complete list.

ZWO also offers a unified ASCOM controller to control all your accessories via the ASCOM/Alpaca platform. This controller can be downloaded for free from the ZWO website.

For Linux and Mac users, there are free Indi or Indigo drivers available on their respective websites. Control is achieved via KStars/Ekos software (on Linux) and CloudMakers' AstroImager/AstroTelescope software (on Mac). Finally, ZWO cameras can be accessed using video drivers such as DirectShow or TWAIN.
