ZWO ASI183MM USB3.0 Monochrome Camera: Unleashing Sensitivity and Speed in Astrophotography

Cutting-edge Sensor Technology: Featuring the Sony IMX183CLK-J CMOS sensor, this camera delivers exceptional sensitivity and quality. With a diagonal of 15.86 mm and approximately 20.48 million effective pixels, it offers a high resolution of 2.4 μm square pixels.
High Sensitivity and Dynamic Range: Achieves an astounding peak Quantum Efficiency (QE) of 84%. This, combined with a large full well capacity of 15000e, low read noise of 1.6e at 30dB, and a dynamic range of 12 stops at Gain=0, ensures top-notch astrophotography performance.
Versatile Imaging Capabilities: Ideal for a wide range of applications including solar (white light) and lunar imaging, electronically assisted astronomy (EAA), and planetary imaging. Capable of high frame rates up to 19fps at full resolution (5496×3672) in both 10-bit and 12-bit ADC modes.
Advanced Back-Illuminated Sensor Design: Employs Sony’s Exmor R technology for exceptional deep-sky imaging performance. The back-illuminated structure significantly enhances light collection efficiency.
High Frame Rate Options: Offers various FPS settings for different resolutions, ensuring fast and efficient imaging in various conditions and applications.
Effective Light Utilization: The high QE ensures that a substantial percentage of incoming light is effectively used, enhancing image quality, especially in visible spectrum ranges.
USB 3.0 and ST4 Ports: Equipped with a USB 3.0 port for rapid data transfer up to 5Gb/s, enabling smooth and fast frame rates. Also includes an ST4 port for easy auto-guiding connection with mounts.
User Feedback and Recommendations: Based on user feedback, the IMX183 sensor exhibits grid pattern noise during Ha solar imaging. It is advised to use flat frames for calibration. For Ha solar imaging, the ASI1600 or ASI174 mono cameras are recommended.
Note on QE and Solar Imaging: While the QE remains over 60% in the Ha channel, users are advised to be aware of the sensor's characteristics in specific imaging conditions.
