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 IMX183CLK-J CMOS Sensor
The sensor the ZWO ASI183MM utilizes is the 20.18-megapixel Sony IMX183CLK-J. As opposed to its color counterpart, the ASI183MC, the monochrome design of the ASI183MM does not have a Bayer pattern to filter the incoming light into its corresponding color value. As a result, this monochrome sensor converts every photon collected into signal, greatly improving its sensitivity. This can be seen in the higher peak QE value of 84% as opposed to the ASI183MC’s peak QE value of 80%. The large 5496×3672 resolution coupled with the small pixel size of 2.4um delivers excellent performance in its resolution of detail. Aiding in contrast and allowing for 12 stops of dynamic range is the full well capacity of 15Ke and 12bit ADC.
Electronic Highlights
In typical CMOS sensors, the metal wiring within the sensor sits on top of the pixel wells, reducing the amount of light entering the pixels. The innovative craftsmanship of the Sony IMX183CLK-J increases photon collection significantly. Adopting a back illuminated sensor design, the ASI183MM has the wiring behind the pixels for maximum light collection. This increase in light gathering ability allows for an improvement in signal to noise ratio for higher quality photos.
USB 3.0 and ST4 Guide Port
Two types of connection ports are available on the ASI183MM for great versatility. While engaging in high speed imaging, a reliable mode of data transportation is necessary in order to reduce buffer time and preserve the frames captured. The large 5Gb bandwidth USB3.0 port allows the ASI183MM to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode) at full resolution. Wanting to utilize this highly sensitive camera for guiding? Connect your camera to your telescope mount through the ST4 port, or directly to your computer with the USB3.0 port!
