ZWO ASI533MC Pro DSO camera

Posted on Sunday, April 21, 2024 by RICHARD HARRIS, Executive Editor

The ASI533MC PRO camera integrates Sony's advanced IMX533, a 1-inch square, 9.07MP back-illuminated CMOS image sensor, specifically designed for high-definition, low-noise imaging. It boasts a pixel size of 3.76 microns and can capture up to 20 frames per second in 14-bit mode. The low read-out noise, comparable to SCMOS or EMCCD sensors, makes it highly effective for capturing detailed astronomical images.

ZWO ASI533MC Pro DSO camera key features:

  • High Definition Imaging: 9.07MP resolution with a 3.76 µm pixel size.
  • Fast Frame Rate: Up to 20 frames per second in 14-bit mode.
  • Low Noise Performance: Read-out noise as low as 1.0e.

 

 

 

 


55mm back focus length

Sony's back-illuminated technology in the ASI533MC PRO significantly enhances sensitivity and reduces noise, crucial for astrophotography. This design minimizes the degradation of sensitivity due to obstructions like metal wiring and transistors, which are moved to the reverse side of the silicon substrate. The unique photo-diode structure and on-chip lens optimized for back-illumination contribute to superior image quality.

Optical Design:

  • Back-Illuminated Sensor: Enhances light gathering and improves noise reduction.
  • Optimized Pixel Structure: Increases sensitivity and reduces random noise.
  • Advanced Optical Components: Custom photo-diode structure and on-chip lens for sharper images.

 


ZWO ASI533MC PRO USB 3.0

The ASI533MC PRO is equipped with a USB 3.0 interface, ensuring quick data transfer rates, and includes 256MB DDR3 memory for stable downloading of frames. This camera is designed to be powered by an external DC 12V @3A~5A power supply, and it supports various power options including compatible lithium batteries. It is crucial to use the correct voltage to prevent damage to the camera.

  • USB 3.0 Interface: For high-speed data transfer.
  • External Power Supply: Requires DC 12V @3A~5A, compatible with lithium batteries.
  • Memory Support: 256MB DDR3 for efficient frame handling.Z
