Editor’s Review
Introduction
The ZWO ASI174MM Monochrome CMOS Astronomy Camera – USB 3.0 Camera Sensor is a cutting-edge imaging camera designed specifically for astronomy enthusiasts. With its Sony Exmor IMX174 2.35MP sensor and Pregius global shutter technology, this camera offers exceptional image quality for capturing solar, lunar, planetary, and deep sky object images. In this review, we will explore the features and performance of this camera in detail.
Sony IMX174 CMOS Sensor
The standout feature of the ASI174MM is its Sony IMX174 monochrome CMOS sensor. This type 1/1.2″ Sony CMOS image sensor features a 5.86¬µm unit pixel in a 1936 x 1216 array, providing high resolution images with incredible detail.
Pregius Global Shutter Technology
The Sony IMX174 CMOS sensor incorporates Pregius global shutter technology, which allows for simultaneous scanning of all pixels. This global shutter function is crucial for capturing images of moving objects, as it eliminates focal plane distortion. When conducting solar or lunar imaging, factors such as bad seeing, wind, or movement can distort the image if the readout speed is not quick enough. The ASI174MM’s global shutter function ensures that such distortions are avoided, resulting in improved image quality.
Sony Exmor Technology
The ASI174MM utilizes Sony Exmor technology, which employs column-parallel A/D conversion for high-speed processing, low noise, and low power dissipation. This technology enhances the camera’s performance, allowing for high frame rates and accurate image capture. Additionally, the camera offers the ROI (Region of Interest) mode, which enables users to capture up to 16 areas within the effective pixels. This feature further enhances the camera’s versatility and allows for even higher frame rates.
High Quantum Efficiency
The ASI174MM boasts a high quantum efficiency (QE), estimated to have a peak value of approximately 77%. This means that the camera is highly efficient at capturing photons, resulting in more accurate and detailed images. The high QE is particularly beneficial when capturing dim or faint celestial objects, as it maximizes the camera’s sensitivity to light.
Compact Design and Back Focus Length
With its compact design, the ASI174MM is lightweight and easy to handle. The camera measures only 62mm (diameter) x 36mm (length), allowing for easy integration into various telescope setups. Additionally, after removing the T2 11mm ring, the back focus length is reduced to a mere 6.5mm. This minimal back focus length ensures compatibility with a wide range of telescopes and accessories, making the camera highly versatile.
Drivers and Softwares
ZWO provides the latest camera drivers and a wide range of DSO and Planetary capture software on their website. It is important to install the newest driver and software to ensure optimal performance when using the ASI174MM. These tools and resources enhance the camera’s usability and allow users to fully unlock its potential.
Conclusion
The ZWO ASI174MM Monochrome CMOS Astronomy Camera – USB 3.0 Camera Sensor is a powerful imaging tool for astronomy enthusiasts. With its Sony IMX174 CMOS sensor, Pregius global shutter technology, and Sony Exmor technology, this camera delivers exceptional image quality, allowing users to capture stunning solar, lunar, planetary, and deep sky object images. Its high quantum efficiency, compact design, and compatibility with various telescopes make it a versatile and reliable choice for astrophotography. With the added convenience of readily available drivers and software, the ASI174MM camera is a must-have for any serious astronomer.
