The ASI183MM Pro is a cooled monochrome camera featuring a Sony IMX183 sensor with a resolution of 5496 × 3672 pixels and a pixel pitch of 2.4 µm, making it suitable for high-resolution imaging at short focal lengths. It allows for filter-based image acquisition, requiring careful calibration of amp-glow and verification of the risk of oversampling at long focal lengths.

The ASI183MM Pro is a cooled monochrome camera whose Sony IMX183 sensor offers 5496 × 3672 pixels on a 13.2 × 8.8 mm area. Its unique feature lies in its small 2.4 µm pixels: they allow for fine sampling without requiring a long focal length. It is therefore worth considering for use with a short, well-corrected telescope when seeking to preserve detail in the structures of nebulae or in small objects within the field of view.
About 20 megapixels at this format don’t provide the same field of view as a large sensor. Before making your choice, simulate the framing using the actual focal length, including the teleconverter. At long focal lengths, these pixels can lead to oversampling: tracking demands increase without necessarily revealing more detail amid turbulence. Precise focusing and consistent tracking are therefore just as important as resolution. This model stands out for the fineness of its pixel pitch, not for a universal promise of superior resolution.
Without a color filter array, the sensor is used for luminance acquisitions or behind selected filters. A color image requires separate series of exposures and their combination, for example in RGB or with a selection of narrowband filters suitable for emission nebulae. Allow sufficient time per channel and plan for the installation of a filter wheel if your project requires it. The built-in USB 2.0 hub allows you to connect accessories, while the main USB 3.0 connection transfers images to the acquisition system.
The advertised maximum capacity is 15,000 electrons, and the conversion is performed using 12 bits. Bright stars can therefore require shorter exposure times than the faint extensions of the target alone would suggest. Readout noise depends on the gain; ZWO quotes 1.6 electrons at 30 dB. The buffer and internal processing limit amp-glow, but this model is not advertised as being free of this glow. Take dark frames with the same exposure time, temperature, and settings as your images to calibrate this signal consistently.
Active cooling helps control thermal noise during long exposures. The product datasheet specifies a temperature difference of 35 °C below ambient; it is important to maintain a control margin rather than systematically aiming for the lowest possible temperature. ZWO requires an external power supply of 11 to 14 V, even when cooling is not in use, and recommends a suitable 12 V power supply. Do not rely solely on the USB cable.
The advertised frame rate reaches 19 frames per second at full resolution, with higher frame rates in a reduced window. This also makes it suitable for lunar imaging, but the camera is primarily intended for finely sampled deep-sky imaging. An important point for another application: ZWO notes a possible grid pattern in H-alpha solar imaging and recommends using flat-field images. It is therefore not the simplest choice for this specialty; furthermore, all solar imaging requires appropriate and properly installed solar filters.

The ZWO ASI183MM Pro is designed for deep-sky photography using long exposures: nebulae, galaxies, and clusters. Its cooling system (40 °C below ambient temperature) keeps thermal noise very low during exposures lasting several minutes. With its 2.4 µm pixels, it works well with instruments with focal lengths of approximately 250 to 500 mm (1 to 2″ per pixel). In monochrome mode, it can be used with LRGB or narrowband filters (Hα, OIII, SII) and remains effective under urban skies.
The Sony IMX183 packs 20.2 Mpx onto a 1″ sensor thanks to very small 2.4 µm pixels: plenty of detail at short focal lengths (camera lenses, small eyepieces). On the other hand, the well capacity is modest (15 ke⁻), and bright stars saturate more quickly.
The cooling system requires an external 12 V DC power supply; 3 A is recommended (5.5 × 2.1 mm connector, center positive). It is not included with the camera: we recommend the'Pegasus Astro 12 V 10 A power supply (2.1 mm plug). In the field, a Pegasus Astro unit like the Pocket Powerbox Advance It also powers the mount and the heating elements from a single source. Without a 12-volt power supply, the camera operates via the USB cable, but without cooling.
The camera's back focus is 17.5 mm (6.5 mm without the removable 11 mm T2 extension ring). Mounts: 2″ and M42 × 0.75. If using a corrector or reducer that requires 55 mm, make up the difference with extension rings, taking into account the filter wheel or filter drawer, if present.
For color photography with the ZWO ASI183MM Pro, you need a filter wheel: for this sensor, the ZWO EFW 8 × 1.25″ Filter Wheel is suitable. When it comes to filters, we recommend the Antlia line: the Antlia LRGB-V Pro Kit for galaxies and clusters, and filters Antlia Hα Pro 3 nm, OIII Pro 3 nm and SII Pro 3 nm For narrow-band nebulae, choose the 1.25″ mounted version.
With a ZWO OAG Optical Splitter and a small guidance camera like the ZWO ASI220MM Mini, you guide through the main telescope. A guide scope such as the'Askar 32 mm is the simplest alternative.
Yes: A built-in USB 2.0 hub allows you to connect a filter wheel, a guide camera, or a focuser directly to the camera, reducing the number of cables running to the computer.
The monochrome version is more sensitive and produces better results in narrowband, but it requires a filter wheel. The color version, the ZWO ASI183MC Pro, produces a color image in a single exposure.

Here are a few accessories we've selected for this model, depending on your needs.
Select the 2-inch mounted unit. Check the mounting and the height of the filter mounts.
SHO 3 nm 2-inch set, mounted. Check the focal ratio and the height of the filter mounts.
7 × 2-inch wheel. Check the height of the filter mounts, the connections, and the draft.
The ZWO setup shown here, which includes a 2-inch wheel, requires a 5-mm M42 tilt plate (sold separately) and a 1-mm M42 spacer. Check the parts you receive, the connections, the focus, and the prism; guide camera sold separately.
ZWO 12 V / 5 A power supply—optional if you don't already have a suitable power source. Check the connector, polarity, and the power requirements for your setup.
Optional ZWO 8-position filter wheel, as an alternative to the 2-inch filter wheel. It accommodates either mounted 1.25-inch filters or unmounted 31-mm filters, to be selected separately; the recommended 2-inch filter sets do not fit in this wheel. Check the M42 threads, the filter dimensions, the focal length, and vignetting based on your optics.
