ZWO ASI585MM USB3.0 Monochrome Astronomy Camera
A Highly Sensitive Monochrome Astronomy Camera from ZWO!
As one of the latest monochrome planetary cameras from ZWO, this ASI585MM is perfect for those looking to take their short exposure astrophotography to the next level. The outstanding sensitivity offered by this camera opens the doors to stunning images of Jupiter, Saturn, our Moon, and plenty more. Using the method of Electronically Assisted Astrophotography (EAA), you can even capture small, distant objects, such as galaxies, enabling you to explore deep space. Packed with qualities like incredible low light performance, large resolution, and fast transmission speeds, this feature-rich ASI585MM is sure to impress!
Fitted with STARVIS 2 technology from Sony, the onboard Sony IMX585 sensor offers a wider dynamic range and exceptional near-infrared sensitivity for sharp, crisp images. Also, this sensor features a back illuminated design for superb signal collection as well as a low readout noise. The result? Stunning images with a high signal-to-noise ratio! In addition to outstanding sensor performance, this camera comes equipped with quality of life improvements to help you elevate your nights under the stars, such as a DDR3 memory buffer, a reliable USB 3.0 port, and zero amp glow. With these top-of-the-line aspects, the ASI585MM Monochrome Astronomy camera from ZWO is a must have!
A High Performance, Professional Camera for Astrophotography
Let's Dig into the Data!
What sets one astrophotography camera apart from another? How is performance measured? Camera and sensor manufacturers provide certain interconnected specifications that give insight into the performance of a camera. These measurements include quantum efficiency, read noise, full well depth, gain, dark current, and dynamic range. While the graphs provided by the manufacturer may be confusing or intimidating, don't fret! Our team has put together a breakdown of these complicated topics to help you make sense of them. Take a look at the article here: Understanding ZWO Camera Charts and Graphs, and feel more confident making the right choice for your astrophotography needs!
Sony IMX585 CMOS Sensor
Assembled with the Sony IMX585 sensor, enjoy capturing stunning 4K images thanks to the 3840x2160 resolution. This total of 8.29 megapixels and small 2.9 µm pixel size is wonderful for collecting intricate details on our solar system neighbors. In the absence of a Bayer Matrix, the monochrome design of this camera utilizes every pixel well, making it much more effective at signal collection than its color counterpart, the ASI585MC. This efficacy in signal conversion can be seen with the rated 91% peak QE value. Additional qualities include a low readout noise of 0.7e for crisp, clean images, and a 40Ke full well capacity for beautiful gradients within the captured frames. The exceptional performance offered by this sensor can be credited to the STARVIS 2 technology, a breakthrough innovation from Sony.
Electronic Highlights
Enhancing performance even further, ZWO has equipped this ASI585MM camera with specialized hardware. The sensor itself features a backlit design, meaning the necessary wires and transistors are fixed behind the sensor as opposed to in front of it. This greatly improves signal collection without obstructions in the way of the pixel wells, increasing the signal to noise ratio within your captured frames. As planetary imaging and EEA involve collecting a large amount of data in a short amount of time, it’s vital to have a system in place to streamline data transfer. Understanding this, this ASI585MM is housed with a 256MB DDR3 memory buffer to ensure smooth, consistent data transmission to your computer without lag, even at the max frame rate of 46.9 FPS. Additionally, careful wiring within this astronomy camera eliminates amp glow, delivering cleaner, more detailed images!
USB 3.0 and ST4 Guide Port
On the body of this ASI585MM, you’ll find two means of connection: a USB 3.0 port and an ST4 guide port. The USB 3.0 port features a wide 5Gb bandwidth for fast, reliable data transmission. This interface allows you to collect data at the maximum frame rate of 46.9 FPS in full 8.29MP resolution! If you’re wishing to utilize this camera’s high sensitivity for guiding, easily do so with this USB 3.0 port, or connect it directly to your mount via the ST4 port.
