High-Resolution Sony IMX183 Sensor – Ideal for Planetary and Lunar Imaging
At the heart of the ZWO ASI183MM is the Sony IMX183 monochrome sensor, featuring a 5496 x 3672 pixel arraythat captures fine details with remarkable clarity. The small 2.4-micron pixels allow for incredibly high sampling rates, making this an excellent choice for high-resolution planetary imaging.
Whether you’re capturing the intricate surface of Jupiter’s swirling cloud bands, Saturn’s ring divisions, or the rugged craters of the Moon, the ASI183MM’s resolution ensures that no detail is lost. This pixel size also provides excellent sampling for short focal length telescopes, making the camera a great match for a wide range of optical systems.
Fast Frame Rates for Lucky Imaging
For planetary, solar, and lunar imaging, high-speed capture is essential. The ASI183MM excels in high-frame-rate imaging, allowing you to take advantage of short exposures and freeze atmospheric turbulence using lucky imaging techniques.
- 19 fps at full 20MP resolution (5496 x 3672)
- 41 fps at 10-bit mode (5496 x 3672)
- 308.17 fps at 320 x 240 resolution
These speeds allow you to collect thousands of frames in a matter of seconds, dramatically improving the final stacked image. Combined with its low read noise, the ASI183MM delivers exceptionally clean planetary and lunar images, even in challenging seeing conditions.
Outstanding Sensitivity and Quantum Efficiency
The back-illuminated Sony IMX183 sensor offers an impressive peak quantum efficiency (QE) of 84%, meaning a significant portion of incoming light is converted into useful image data. This results in brighter, more detailed planetary and lunar images, even with short exposures.
For solar imaging, this level of sensitivity ensures that fine details such as granulation, prominences, and sunspot structures are captured with clarity, particularly when using specialized filters like hydrogen-alpha or calcium-K.
Ultra-Low Read Noise for Maximum Image Clarity
One of the standout features of the ASI183MM is its ultra-low read noise, which reaches as low as 1.6e in high-gain mode. This is critical for high-speed planetary imaging, as it ensures that fine details remain visible without excessive graininess.
Low noise performance is especially beneficial when working with high-magnification imaging, where every subtle detail matters. Whether you're capturing the delicate bands of Saturn or the wisps of detail in Mars' surface features, the ASI183MM allows you to push your images further.
Optimized for Solar Imaging
The ASI183MM is an excellent choice for solar photographers, providing the high frame rates and sensitivity needed to capture solar prominences, granulation, and sunspots with stunning detail.
The combination of:
-
High-speed data transfer (ensuring smooth, flicker-free video)
- Small pixels for high-resolution imaging
- High quantum efficiency for capturing faint solar features
makes this camera an outstanding option for both white-light and hydrogen-alpha solar imaging.
Deep-Sky Capabilities as a Secondary Feature
While optimized for planetary and solar work, the ZWO ASI183MM is also capable of deep-sky imaging with the right setup. The small pixel size makes it best suited for short focal length telescopes, where it can capture fine details in galaxies, nebulae, and star clusters.
For those interested in narrowband imaging, the monochrome sensor allows for precise Ha, OIII, and SII imaging, bringing out contrast and detail in faint deep-sky objects. Unlike its cooled counterpart, the ASI183MM is better suited for short and medium-exposure deep-sky imaging rather than extreme long-exposure work.
If deep-sky imaging is your primary focus, you may want to consider the ASI183MM Pro version, which includes built-in TEC cooling for better thermal noise management.
Zero Amp Glow for Cleaner Images
One common issue with some CMOS sensors is amp glow, which appears as an unwanted brightness in the corners of long-exposure images. The ASI183MM eliminates amp glow completely, ensuring cleaner images without the need for complex calibration.
This is especially beneficial when shooting lunar and planetary video sequences, as it ensures a uniform backgroundacross all frames.
USB 3.0 High-Speed Data Transfer
To handle the high data rates required for planetary imaging, the ZWO ASI183MM is equipped with a USB 3.0 interface. This allows for lightning-fast frame capture, reducing lag and ensuring smooth recording of high-speed sequences.
The camera also features a built-in 256MB DDR3 memory buffer, which helps prevent data loss during high-speed imaging sessions.
Who Should Buy the ZWO ASI183MM?
This camera is a top choice for planetary, lunar, and solar astrophotographers who want a high-resolution, high-speed monochrome CMOS sensor that delivers exceptional detail and sensitivity.
Best Suited For:
-
Lunar imaging – Capture craters, rilles, and maria in stunning high resolution.
-
Planetary imaging – Resolve fine cloud bands on Jupiter, Saturn’s Cassini Division, or Martian surface features.
-
Solar imaging – Record solar prominences, sunspots, and granulation in high-speed video.
-
Deep-sky imaging (secondary) – Best suited for wide-field setups or short-exposure narrowband imaging.
Less Ideal For:
-
Extreme long-exposure deep-sky imaging – Consider the ASI183MM Pro (cooled version) for better thermal management.
-
Users preferring a color camera – This is a monochrome sensor, meaning LRGB or narrowband filters are needed for color imaging.
Final Thoughts
The ZWO ASI183MM is a powerful, high-resolution monochrome camera that excels in planetary, lunar, and solar imaging. With small 2.4-micron pixels, high-speed USB 3.0, ultra-low noise, and superior quantum efficiency, this camera is the perfect tool for capturing breathtaking detail in the solar system.
While it offers some secondary deep-sky capabilities, its real strength lies in high-frame-rate planetary and solar imaging, where it delivers unmatched clarity and precision.
If you're serious about capturing the finest details in the Moon, planets, or Sun, the ASI183MM is the camera that will take your imaging to the next level.
ZWO has all their information available for download on their website in a perfectly laid out section. Check it out here for software and drivers and here for manuals and guides.
One of the coolest gadgets, and a neccessity according to a majority of ZWO users, is the ASIair Plus. It is an all-in-one wireless camera solution.
