Visit ZWO ASI585MC Pro<\/strong> is a cooled color camera designed to meet the needs of astrophotographers looking for a high-performance, versatile solution for photographing deep-sky objects. Based on the Sony IMX585 4K CMOS sensor<\/strong>, it combines excellent sensitivity, high resolution, and low noise. Its particularly attractive price point makes it an affordable yet high-performance solution for both beginners and those looking to advance in Deep-Sky Astrophotography<\/strong>.<\/p>\n At the heart of the ASI585MC Pro is a Sony CMOS sensor in the 1\/1.2 inch<\/strong>, with pixels as small as 2.9 \u03bcm<\/strong>. This design provides a resolution of 3840 x 2160 pixels<\/strong>, for a total of 8.29 megapixels<\/strong>. This high resolution allows for the capture of a great deal of detail and is particularly well-suited for imaging galaxies, nebulae, star clusters, and other deep-sky objects.<\/p>\n The technology STARVIS 2<\/strong> further enhances the sensor's performance. Thanks to its back-illuminated structure, the Sony IMX585 offers excellent light sensitivity and effectively captures faint signals from celestial objects. As a result, the camera maintains a very high level of detail, even when photographing dim targets.<\/p>\n The ASI585MC Pro isn't limited to deep-sky astrophotography. In high-speed mode, it can reach up to 47 frames per second at full resolution<\/strong>. This high frame rate is particularly useful for capturing images of the Sun, the Moon, and the planets, where taking a large number of images allows you to select the best ones and minimize the impact of atmospheric turbulence.<\/p>\n This versatility makes the ASI585MC Pro a true versatile astronomical camera<\/strong>, capable of switching from long-exposure imaging of deep-sky objects to the rapid image acquisition required for planetary astrophotography.<\/p>\n The sensor's back-illuminated structure also improves its ability to accumulate electrons. Despite its small pixels of 2.9 \u03bcm<\/strong>, the ASI585MC Pro achieves a full-well capacity of 40 ke-<\/strong>, which is nearly three times that of the previous-generation IMX485 sensor.<\/p>\n A high full-well capacity allows the sensor to collect more light before reaching saturation. This helps preserve detail in bright areas, limit overexposure, and achieve a best signal-to-noise ratio<\/strong>, especially when the image contains both very bright regions and particularly dim areas at the same time.<\/p>\n One of the major advantages of the ASI585MC Pro is its built-in technology Zero Amp Glow<\/strong>. Unlike some CMOS cameras, the sensor does not exhibit the characteristic glow that can appear in dark areas during long exposures.<\/p>\n This function is implemented directly in the hardware level<\/strong> and therefore requires no specific software control. It produces exceptionally clean dark frames and makes it easier to process astrophotographs, regardless of the exposure time or gain level used.<\/p>\n For long exposures, the ASI585MC Pro features a two-stage TEC cooling system<\/strong>. This allows the temperature of the CMOS sensor to be lowered by more than 35 \u00b0C above room temperature<\/strong>. By lowering the sensor temperature, the system limits the current of darkness <\/strong>and thermal noise, which results in cleaner images during long exposures.<\/p>\n A Delta T value of 35 \u00b0C was measured at an ambient temperature of 30 \u00b0C. Actual performance may vary depending on operating conditions and ambient temperature.<\/p>\n The ASI585MC Pro also includes a HCG (High Conversion Gain) mode<\/strong> which effectively reduces read noise as gain increases, while maintaining a wide dynamic range. When the gain reaches 252<\/strong>, HCG mode is activated automatically.<\/p>\n At this level, the dynamic range remains close to 11 bits<\/strong>, while the operating noise can drop to as low as 0.7 e-<\/strong>. This combination is particularly useful for bringing out fine details in deep-sky objects while maintaining good control over the bright areas.<\/p>\n Thanks to its Sony IMX585 4K sensor<\/strong>, its TEC cooling system, its technology Zero Amp Glow<\/strong>, its quiet operation, and its speed of up to 47 frames per second<\/strong>, the ZWO ASI585MC Pro is a particularly comprehensive solution for astrophotography. Its excellent sensitivity makes it ideal for deep sky<\/strong>, while its fast shooting speed and versatility also allow it to photograph the Moon, the Sun, and the planets.<\/p>\nHigh-resolution Sony IMX585 4K sensor<\/h3>\n
