Monochrome astronomical camera for astronomical imaging and compatible mounts.
The monochrome version captures light without a color matrix. To create a color image, plan to take images with the appropriate filters and combine them during processing. It also allows you to work with narrowband filters depending on the target. For short-exposure acquisitions, the effective frame rate depends on the readout mode, the selected area, and the actual data throughput of the computer. Pixel size must be considered in relation to the focal length and turbulence conditions. Before assembly, check the thread, the distance between the sensor and the adapter, and the space occupied by the filters or the optical splitter. The sensor alone does not determine the final field of view: the instrument, the focal length, and any reducers also play a role. Take your calibration images using settings consistent with those used for observations. An astronomical camera provides no protection for solar observation: any use on the Sun requires a filter specifically designed for the instrument and installed correctly.
Documentation and Compatibility: ZWO official data sheet.
The ZWO ASI183MM is designed for planetary, lunar, and solar imaging (the Sun only with a suitable filter) using «lucky imaging»: you capture footage for a few minutes at up to 19 frames per second, then stack the best frames. With 2.4 µm pixels, aim for an F/D ratio of approximately f/7 to f/12 when imaging planets, using a Barlow lens if necessary. It is also suitable for electronic-assisted astronomy (EAA): short exposures stacked in real time on bright deep-sky objects.
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.
No: It is powered by its USB cable. No external power source is required.
The camera's back focus is 6.5 mm or 17.5 mm, depending on the adapter. Mounts: 2", 1.25", and M42 × 0.75.
