ZWO ASI585MC Pro review by Trevor Jones
Trevor Jones delves into the ZWO ASI585MC Pro, a cooled astronomy camera celebrated for its high-quality images and affordability. Despite its smaller sensor and 12-bit ADC, which might limit the field of view and dynamic range compared to DSLRs, Jones highlights the camera's high sensitivity and ability to capture 50 frames per second, making it ideal for planetary imaging and live stacking. He shares his initial experiences with the camera, capturing images of the Sharpless 112 nebula and the Crescent nebula.
Jones acknowledges some challenges, such as noticeable gradients and potential calibration issues, especially when shooting during a full moon and in city lights. However, he expresses excitement about the camera's potential for deep-sky astrophotography. He plans to use further processing tools to enhance image details.
When discussing the Crescent nebula, Jones praises the camera's performance but notes some odd artifacts and brightening events in the subframes. Despite these anomalies, he achieves a great image and encourages other users to share their experiences with the camera.
Overall, Jones believes the ZWO ASI585MC Pro is a promising option for astrophotographers seeking an affordable and dedicated astronomy camera. Watch the full video below.
