The ZWO ASI533MC-Pro is a high-performance cooled color astronomy camera ideal for capturing deep-sky objects, as well as high-resolution images of the Moon, Sun, and planets. Its square-format sensor, advanced cooling system, and innovative design make it a versatile tool for astrophotographers of all levels.

Key Features

• Square 1” Sony IMX533 Sensor
  Equipped with a 9-megapixel back-illuminated CMOS sensor with 3008x3008 resolution and 3.76µm pixels, the camera is perfect for framing symmetric celestial objects like star clusters and nebulae.

• Enhanced Image Quality
  The back-illuminated design improves sensitivity and reduces noise, with a high quantum efficiency (QE) of 80% and low read noise of just 1.0e. The sensor’s 50,000e full well capacity ensures bright stars remain sharp without saturation.

• Zero Amp Glow
  Features advanced circuitry to completely eliminate amp glow, even during long exposures at high gain, resulting in cleaner, more accurate images.

• Efficient TEC Cooling and Anti-Dew Heater
  A two-stage TEC cooling system reduces sensor temperature by up to 35°C below ambient, minimizing noise. The heat generated by the cooler also prevents dew formation on the camera window.

• Fast Data Transfer
  Includes a 256MB DDR3 memory buffer for stable data transfer and reduced amp glow. The USB3.0 port supports fast data rates of 20 fps at full resolution.

• Dynamic Range and Low-Noise Performance
  Offers a dynamic range of up to 14 stops, with optimal performance at a gain setting of 100. This makes it well-suited for electronically assisted astronomy (EAA) and traditional astrophotography.

Compact and User-Friendly Design

The ASI533MC-Pro is ideal for both deep-sky imaging and solar-system photography. Its compact size, powerful cooling, and versatile square sensor make it a perfect choice for astrophotographers seeking excellent performance and reliability in a streamlined package.

Traditional equatorial mounts often require heavy counterweights, making it challenging to balance the right ascension (RA) and declination (DEC) axes. They are cumbersome to transport and store, causing significant inconvenience for amateur astrophotographers during outdoor sessions. Additionally, some strain wave gear mounts have limited functionality, insufficient payload capacity, and lack stability during use. Addressing these issues, ZWO has developed the ASI Mount series, which eliminates the need for counterweights.

The AM3 weighs only 3.9 kg and supports payloads ranging from 8 kg to 13 kg. While portability is crucial, ZWO prioritizes stability to ensure a reliable user experience. The optimized internal structure incorporates harmonic drive reducers and timing belts, delivering precise control and an impressive 300:1 reduction ratio. The mount is versatile, functioning as either an equatorial or an alt-azimuth mount, and can be controlled via Wi-Fi, Bluetooth, or a handheld controller.

Key Features

Portability and Stability
The optimized internal structure, featuring harmonic drive reducers and timing belts, ensures precise control and stability, achieving a remarkable 300:1 reduction ratio.

Custom Strain Wave Gears
ZWO developed specialized strain wave gears tailored to astrophotography needs, offering extremely low periodic error and high torque. Each mount undergoes factory testing and comes with a unique PE curve to guarantee quality.

Lightweight Design
At just 3.9 kg, the AM3 strikes a balance between portability and stability, prioritizing dependable performance over extreme weight reduction.

8 kg to 13 kg Payload Capacity
Without Counterweights: Supports up to 8 kg.
With Counterweights: Supports up to 13 kg.
(Counterweights should be mounted on a bar no longer than 20 cm.)

Dual Modes: Equatorial and Alt-Azimuth
